For the fourth consecutive year, Saildrone and the National Oceanic and Atmospheric Administration (NOAA) are sailing a fleet of uncrewed surface vehicles (USVs) into hurricanes to better understand how these storms develop, track and intensify.

Saildrone Explorer USVs are 23 ft long and carry a payload of sensors to measure air, surface and water temperature as well as humidity, barometric pressure, wind speed and direction, salinity and wave height. To withstand major hurricane conditions—winds over 110 mph and waves that exceed 50 ft—they have a shorter and stronger “hurricane wing,” similar to a reefed sail on a sailboat.

Saildrone USVs sail autonomously along prescribed routes, which Saildrone Pilots define according to weather conditions and to meet mission objectives. Saildrone’s science partners in the mission at NOAA’s Atlantic Oceanographic & Meteorological Laboratory (AOML) and Pacific Marine Environmental Laboratory (PMEL) will work closely with Saildrone Mission Control to guide the saildrones into oncoming hurricanes.

As the final group of saildrones was readied for deployment, Tropical Storm Debby was forming in the Gulf of Mexico. Just days after SD-1057 was deployed, the USV sailed through the eye of Hurricane Debby hours before the storm made landfall in Florida. Powered solely by renewable wind and solar energy, the Saildrone fleet will stay at sea for the duration of the mission, which will last through October 2024.

As Hurricane Beryl moved across the Caribbean, the National Oceanic and Atmospheric Administration (NOAA) has partnered with Saildrone to deploy seven hurricane-tracking saildrones in strategic locations.  

These unmanned surface vessels (USVs) are equipped with a specialized “hurricane wing” to withstand extreme wind conditions. The USVs are gathering real-time data on key atmospheric and oceanic parameters such as wind speeds, wave heights, temperature, pressure and salinity​. 

Hurricane Beryl 

Hurricane Beryl impacted Jamaica, the Cayman Islands and the Yucatan Peninsula. Residents were urged to complete preparations to protect life and property as the storm progressed. 

Two saildrones were deployed in the Gulf of Mexico, launched from St. Petersburg, Florida, and Port Aransas, Texas, and five more in the Atlantic Ocean and Caribbean Sea, launched from Jacksonville, Florida, and the U.S. Virgin Islands. These systems provide critical data to improve the understanding and prediction of tropical cyclone intensity changes, particularly rapid intensification — where hurricane wind speeds increase dramatically in a short period​. 

To enhance these efforts, Rutgers University deployed underwater gliders that work in tandem with saildrones. These gliders measure temperature and salinity at various depths, offering a detailed picture of the ocean’s conditions before, during and after a hurricane.  

The collaboration aims to provide high-resolution, coordinated measurements from the ocean surface to the atmosphere, enhancing situational awareness for forecasters and improving the accuracy of hurricane intensity forecasts.

Advanced Technologies  

Equipped with a “hurricane wing,” Saildrone’s USVs can collect continuous data in harsh storm conditions, providing real-time insights into the physical interactions between the ocean and atmosphere. Underwater gliders, deployed by Rutgers, aid in measuring subsurface ocean conditions, which are critical for understanding how variations in temperature and salinity affect hurricane strength. 

The information gathered by these technologies is extremely valuable for enhancing predictive models, ultimately helping to improve disaster preparedness and response. The partnership between Saildrone, NOAA and Rutgers University represents a significant step forward in the use of uncrewed systems for environmental monitoring.

This hurricane and future storms this hurricane season, have the potential to become supercharged as sea surface temperatures have clocked record high temperatures.

Idalia is the ninth named storm to form in the Atlantic in 2023.

In late May, the National Oceanic and Atmospheric Administration (NOAA) predicted that there would be 12 to 17 named storms this year. However, on Aug. 10, NOAA revised its estimate to 14 to 21 storms.

There were 14 named storms last year, after two extremely busy Atlantic hurricane seasons in which forecasters ran out of names and had to resort to backup lists, reported The New York Times.

Dozens Stranded in Tundra

Several vehicles in Rock Springs, Wyoming, were stranded after being led by their map apps or vehicle navigation systems to an unmaintained county road in a blizzard. Several calls were made to the Sweetwater County Sheriff’s Office about stranded vehicles stuck after they were directed to the detour when Interstate 80 was closed due to winter conditions. Similar incidents were reported by other counties, resulting in discussions between the Wyoming Department of Transportation and the companies that develop navigation software.

UAVs contain Western Technology

A Ukrainian intelligence assessment obtained by CNN and CBS reported an Iranian UAV downed in Ukraine contained technology from companies in the United States and other western countries. The White House has since launched an investigation as to how the technology — including semiconductors, GPS modules and engines — were obtained by Iran. The components removed from an Iranian Shahed-136 UAV totaled 52, 40 of which were manufactured by 13 different U.S. companies. The remaining components were manufactured by other western companies and by companies based in Japan, Taiwan and China.

Machine learning helps monitor hurricanes

Researchers may now be able to monitor climate-induced natural hazards by combining satellite technology with machine learning. Researchers were able to use machine learning to study hurricanes that made landfall over the Gulf of Mexico in a series of recent experiments. C.K. Shum, the co-author of the study and a professor at the Byrd Polar Research Center, uses geodesy to study global climate change phenomena. Using geodetic data gathered from satellites, Shum tested whether a mix of remote sensing and machine learning analytics could accurately monitor weather phenomena. Accurate measurements could help improve hurricane forecasting.

The power of TikTok is real

TikTok changed Jeff Foulk’s life when his daughter posted about his free marine navigation app, Argo, when they attended a boat show in Chicago. Foulk was promoting Argo with little success, until his daughter shared with the social media platform his struggle as the owner of a small business. Since then, the app has been downloaded more than 200,000 times and remains at the top of the charts for boat navigation apps. Argo was launched more than four years ago and, until now, had only 100,000 total downloads. Now that Argo is viral, Foulk wants to launch a premium subscription.

Since Nov. 26, NASA’s Cyclone Global Navigation Satellite System (CYGNSS) team has not been able to make contact with one of the eight CYGNSS spacecraft, FM06.

The team is still working to acquire a signal and establish a connection.

The other seven spacecraft continue to operate normally and have been collecting science measurements since the FM06 anomaly.

CYGNSS is a constellation of eight small satellites taking measurements of ocean surface winds in and near the eye of the storm throughout the lifecycle of tropical cyclones, typhoons and hurricanes.

If the team isn’t able to reestablish contact, loss of the FM06 satellite would primarily affect the constellation’s spatial coverage. However, the CYGNSS constellation can continue to meet its scientific requirements and objectives.

CYGNSS was launched Dec. 15, 2016, and completed its prime mission science objectives on March 19, 2019. It has been operating in extended mission status since then.

The surveying profession has experienced a plethora of advancing technology over the past two decades and it does not look like there will be a slowdown any time soon. From robotic total stations to laser scanning to the use of multiple GNSS constellations, the profession is constantly adapting these emerging technologies into a useful tool for daily applications. For most practicing surveyors, it is a challenge to keep up with not just the hardware of these advancements, but also with software, which is being developed in parallel. Have you tried to open and draw a simple figure in any of the industry standard CAD programs lately?

The complexity of these programs, while advancing the capability of many technical professions, forces even the casual user to maintain a regular habit of software education and training. While it may seem primitive to say that a practitioner is a “practicing” surveyor, on-the-job training never stops. Just when the profession thinks there are no more significant advancements, something comes out of left field that truly blindsides us. (See the adoption of UAVS by the surveying profession compared to the public sector…) What do I think will be one of the next “big things” to revolutionize surveying? The technology is already here, and we need to seriously get on board with adoption before we miss another opportunity to highlight the expertise of the profession.

VIRTUAL REALITY and AUGMENTED REALITY (VR & AR)

First, we need to know that virtual reality (VR) and augmented reality (AR) are different, even though many people use these terms interchangeably. The differences are as follows:

Virtual Reality (VR)

• VR is a virtual world generated by computers and programming.
• VR is a closed environment that is fully immersive.
• VR requires a device (specialized glasses and/or a headset).
• Users in the VR experience are limited by the programming and their computer’s abilities.
• The VR experience may be based upon real-world conditions but is a fictional setting.
• Users of VR can travel and experience conditions in real and fictitious places.
• VR can allow users to have experiences that are not physically possible in the real world.
• VR is 75% virtual + 25% real (industry “rule of thumb”)

Augmented Reality (AR)

• AR is typically based on actual physical places.
• AR is an open environment that is partly immersive.
• In AR, the user controls the environment.
• AR combines virtual elements and experiences with real world conditions.
• Experiences in AR can be accessed by computer, tablet, and smartphones.
• AR is useful for product visualization and evaluation.
• AR is 75% real + 25% virtual (industry “rule of thumb”)

It is important to know these difference between the two technologies in order to implement the correct one for the task at hand. However, both will play an important in surveying for generations to come.

USES OF VIRTUAL REALITY TECHNOLOGY FOR SURVEYING

One of the surveyor’s biggest responsibilities is to complete an accurate site conditions model by topographic methods. Once the topographic survey is completed, site designers will utilize this information to create a unique project that works with the existing site conditions. Advances in CAD software and technology allow engineers and architects to design in 3D and blend the new site with the existing conditions, drainage, and utilities. These designs can be further refined into virtual reality models to give the project’s stakeholders a better indication of what the final product will be when construction is completed.

The key takeaway here is that the surveyor is responsible for delivering the existing conditions model. A model that accurately represents the subject site but in digital form enables the design of the project to be more efficient and realistic to meet the client’s expectation. Surveyers, however, will not use virtual reality as much as augmented reality, for many good reasons.

USES OF AUGMENTED REALITY TECHNOLOGY FOR SURVEYING

AR is still in its infancy. Because surveyors have an interest in the existing and proposed conditions of sites, the use of AR becomes an important tool for the future. Merging proposed information with existing site conditions can become the norm, but like many emerging technologies, the profession will need to learn how to embrace it.

To get a better idea of how the technology works and why surveyors need to consider using it, let us look at an application that showcases AR: Pokémon Go. Yes, the smartphone game app that took the world by storm in 2016 and captivated many “trainers” to search the streets for Ultra Balls and characters. (There are still more than 100 million active players worldwide.) Players of all ages have continued to search for elusive items and characters in a high-tech scavenger hunt that is constantly changing, and all based upon the real world around us. By merging a real-time view with game entities at random geographic locations, players move about our world using one of the best examples of AR.

How does this apply to the surveying profession? Surveyors could utilize AR in everyday tasks but that would require having a fully developed 3D design model that could merge with the existing conditions in their visual device. There are a variety of devices for utilizing AR, including smartphones and tablets. Many of the new data collectors running Windows and Android operating systems can also be used for incorporating AR into the field operation. Here are some examples of AR how can be utilized for surveying tasks:

• While construction staking, AR can be used to assist with structure and improvement location. A quick visual check can help confirm staking calculations are consistent with engineering design.
• Use AR to visually check installed improvements, including curbs, utility structures, and paving. Any deviation from the proposed design should be quite evident.
• When establishing property corners, AR will help the field crew quickly determine whether the calculated location is accessible. This can be used for staking out pre-calculated boundary points and/or proposed lot corners in a new subdivision.

Here are a few ideas as to how surveyors could utilize AR in everyday tasks in the future:

• As public utilities are becoming more available within GIS shape files with geographic locations, they could be utilized with AR to help visually establish locations in the field. Mainline utilities and service lines would become easier to physically verify using AR.
• Another GIS shapefile entity, the parcel line layer, could be used to help the surveyor understand where the property owner believes the line(s) to be as opposed to the actual monumented location.
• All reference monuments and benchmarks established by public agencies using geographic location information could enhance the “treasure hunt” of confirming local datum points.

SURVEYING USING AR TO PROTECT THE PUBLIC

Geospatial information has revolutionized our world, so using AR to help when trouble strikes can potentially be a lifesaver. Recently, an oceanfront condominium in Florida collapsed due to structural failure. While the age of the structure precluded it from having any digital geographic location data, any new similar development could be measured and recorded to assist with future emergency needs. Almost all new development has digital surveying, engineering, and architecture and must use local horizontal and vertical datums. Using the proposed information and verifying with post-construction record drawings, the digital record can be created.

It doesn’t take a design flaw to create a public hazard. For instance, a gas leak could render any building, such as the Florida condo, susceptible to catastrophic damage. By having a digital model of the underground structure, emergency crews could use AR to help locate potential open spaces in the building. As is the case with installing fire suppression systems and emergency exits, the cost to create a digital model of a completed building will be well worth it to save lives.

Underground utility corridors within cities, campuses, or manufacturing facilities could also utilize geospatial locations to establish a digital map for future use with AR. It will take time and significant cost to map existing facilities, yet it should be required for new sites to provide this information for emergencies and for use when designing expansions within the site. Having this utility information to use with AR during the design phase could lead to identifying potential problems before construction starts.

Another reason to plan for future safety is how much uncertainty we face in today’s society. At press time, we are coming up on the 20^th anniversary of 9/11. We also just watched Haiti suffer another devastating earthquake. The 2021 hurricane season has also been very active, so that danger looms large, too. Disasters happen all the time with little to no warning. Our world is much more advanced than we were at the turn of the century, so we can use these advancements to map our infrastructure. Let us hope we never need to use the digital information for another disaster akin of 9/11. Instead, let us use it to ensure that we can get to someone in a remote spot if necessary.

THE ROAD TO FUTURE MAPPING AND AUTOMATION

As previously discussed, establishing a digital twin of our world could help provide a better map for establishing parcel ownership, reducing construction conflicts, and offering better planning tools for future expansion. Will it be completed within my lifetime? No, and I doubt it will be done within the next couple of generations after me.

We can, however, get a significant start on capturing the necessary information to begin the process of digitization. Technology has exceeded my expectations just within the past decade, so I can only hope that more advancements will help with building this digital beast. More architects and engineers are utilizing BIM (building information modeling) for 3D design and collaboration. Most municipalities and counties have built some form of GIS that uses one of the standard geographic datums. Surveyors have fully embraced GNSS technology so state plane and national geographic coordinate systems have become the norm. In addition, we are seeing a wide number of consultants use autonomous vehicles (aerial, hydro, and terrestrial) with photogrammetry, LiDAR, and SLAM remote sensing. Another bit of good news is that computing power is higher than ever and that storage space is cheap for all this data. We should also include how 5G has expanded our reach and, with cloud storage, we can work from just about anywhere. We can do so much more than most of us ever dreamed of, so we need to leverage that into creating a digital entity that can be helpful.

HOW TO IMPLEMENT THE LATEST TECHNOLOGY

Augmented reality is one of many new technologies surveyors need to introduce into their toolbox. Many of you may be asking where to begin; my answer, depending on your age, may offend you.

Hire a Gen Zer. Really.

As a Gen Xer, I have come to realize my limitations on technology and being able to fully implement it. The Z generation, while lacking the experience of us wily old guys, see things much differently. The smartphone/tablet/computer, and even the latest data collectors, are designed with them in mind. They grew up playing computer games based in virtual reality, developed excellent hand-eye coordination, and find efficient ways of getting things done. Our surveying world is almost completely digital (when is the last time a client only wanted paper copies of a plat?), so now is the time to make the leap and ditch the drafting table. We have as much to learn from them as they do from us. Together, we can get the surveying profession ready for the next generations. It has been a great profession for us, so let us hand it off to the Z generation. They will (eventually) be glad we did.

How can I help you if I don’t know where you are?

Hurricane Harvey hits. The storm was worsening. Winds were sustained at over 120 mph. Landfall of Hurricane Harvey was expected in 48 hours. Worse, the storm was forecast to stall once overland creating the single worst rain event in United States history.

Texas Governor Greg Abbott  encouraged people to evacuate, especially those in low lying areas. Mayor Turner had only hours to decide the possible fate of millions. Making the call not to evacuate a category 4 hurricane approaching the city could be political suicide. Consider the fallout after Hurricane Katrina. The models clearly showed the extent of flooding and how many people would be trapped in their cars on flooded roads.

“You cannot put 6.5 million people on the road,” said Houston Mayor Sylvester Turner. The mayor’s ultimate decision not to issue an evacuation declaration was based on geospatial models, and as devastating as they were, it showed a better outcome if everyone stocked up, stayed put, and helped each other out after the storm. At least by staying home we will know where people are after the storm.

Gov. Abbott fully mobilized the National Guard and another 30 state agencies responded to the crisis. U.S. Federal Emergency Management Agency (FEMA) calls to action went out to the Coast Guard and volunteer organizations. Small boats, raised axel trucks and Vietnam-era looking personnel carriers were brought in for support, along with helicopters, drones and search and rescue airplanes.

First responders were issued full body waders and foul weather gear. Thousands of hypothermia blankets were stockpiled and cargo trucks carrying food, water and cots headed south. Volunteers from the Cajun Navy, Team Rubicon, the Red Cross, Open Street Maps, Samaritan’s Purse and others positioned their able-bodied forces along the periphery of the storm’s path ready to move in as soon as given the word.

Thursday afternoon the winds and rains began getting increasingly worse. Darkness fell and by 10 p.m. the eye of the storm had made landfall. Rivers and streams began overflowing due in part to the storm surge moving waters upstream. Streets no longer drained the waters. The flooding continued to rise.

Tremendous thermodynamic forces. Hurricanes aren’t a single, solid storm, though they may look like it from satellite imagery. They are enormous atmospheric depressions like a hole formed in the sky and air masses from thousands of miles around rush in to fill the void. These converging air masses create immense thermodynamic forces extending outward from a central vortex in long sweeping radial bands like blades of an enormous turbine.

A hurricane is the cumulative fury of these destructive forces storm after storm after in rapid succession. Winds increase and decrease as the radial bands pass overhead becoming stronger and more constant as the eye approaches. Every plank, nail and screw is tested. Immense gusts like giant hammers breaks away loose thing. Strains of timber and steel shriek in the wind. In seconds sounds of groaning trees and the air fills with flying debris. Rain comes down in torrents.

But in between these spiral bands it slows, sometimes stopping all together, even sunshine or moonlight might break through, but to believe the storm is over would be wrong — maybe dead wrong. Another band will sweep in with gusting, howling wind, thick, heavy clouds and dark skies, and rain, more and more rain, and the rising waters turning into gushing floods. Moments of endless terror turn into hours, the waters rising higher ever higher.

Finally, 49 inches of rain and three days later the storm ended moving offshore. Its destruction shut down the fourth largest city in the United States.

“…Texans have suffered a great hardship, their warmth and resiliency is truly inspiring,” said Gov. Abbott. The overwhelming willingness of people and organizations to help once the storm passed brought its own challenges. A convergence of rescue and recovery teams began.

Leaders needed. It was obvious a coordinated effort needed to happen. Volunteers and organizations needed to work in unison. FEMA had to establish that order. The coordination center was formed, not unlike other disasters, but this time another dimension was added to it. FEMA was aware of social media’s ability to positively impact rescue operations tapping into briefly during Superstorm Sandy, the last large scale disaster to hit the United States, but FEMA lacked the necessary skills and expertise to capitalize on the technology.

It is times like these that the greatest of all resources is realized. When asked what is the greatest asset, the answers most often given are manpower, money, equipment or supplies; however, even if there are plenty of the above, it is quickly realized the greatest resource is leadership. In times of crises, normal authority is laid aside and given to those who can bring order to the chaos.

Christopher Vaughn, the geospatial information officer for FEMA, and Adrian Gardner, the chief information officer for FEMA, were those individuals stepping up to the task at hand. They understood getting better data faster and putting it into geospatial context held the answer. Once done that would be the foundational layer. All the other elements could then be added, like imagery, lots and lots of imagery, both before and after; and then overlay crowdsourced data.

Vaughn, working with his counterparts in the Department of Homeland Security, brought in Homeland Infrastructure Foundation Level Data (HIFLD) layers, along with the Civil Air Patrol and DigitalGlobe’s Open Data Program. Launched in 2017, the program provides before and after imagery. Vaughn understood that the citizen-as-a-censor model provided raw, real-time and relevant information. It had to be tapped into to get control of the rescue operations.

Sophia Liu, Ph.D., an Innovation Specialist and expert in crowdsource efforts was brought in from the United States Geographic Survey (USGS). Liu was the key to unlocking the crowd. She shared her greatest challenge was the misconceptions around the use of social media and an apprehension to using it without proper approvals from public relations. It took some convincing to change these mindsets.

What helped tip the scales in her favor was Hurricane Irma coming right on the heels of Hurricane Harvey and then Hurricane Maria. The disasters were coming in way too fast and the detractors were drowned out by the need for information. Once they saw the value of crowdsourcing, there was little resistance.

Challenges in Puerto Rico. The results spoke for themselves. In Puerto Rico, within only a few weeks of Hurricane Maria’s devastation, 1.4 million homes were analyzed for damage and 24,000 miles of roads were digitized through volunteer groups like GIS Corps and OpenStreetMaps.

One of the greatest challenges in Puerto Rico was the lack of street addresses. That is more common than one might realize. In many parts of the world there is no established address system and locations are more or less oriented to significant landmarks. It is difficult for Americans to understand, but in other cultures generations of families grow up in the same neighborhoods. Everyone knows everyone else. Location is personal. In the case of disasters this poses a huge challenge, especially when roads and landmarks are destroyed, and people have evacuated.

The company What3Words (W3W) is tackling this issue. W3W works uses a pixelated Earth system of 3 meter by 3 meter squares. Each grid can be defined by a set of three words. As I write this I am sitting in bump.cans.dome.

W3W does away with traditional numerical latitude and longitude. It works in any language, in fact, eight countries have partnered with W3W as either the nation’s official addressing system or an alternate system, and the United Nations has it among their disaster reporting tools. Art Kalinski, the former writer of this column wrote an article last year about W3W, what3words: The geospatial advancement of the year?

In Puerto Rico, since there aren’t addresses except in urban areas, the remainder of the island had to be geospatially configured to communicate “where” something was located. Digitizing Puerto Rico is a huge geospatial effort that would take years through normal government protocols and cost millions of dollars.

Instead, by enlisting the support of the crowd, it was accomplished in weeks, proving the power if crowdsourcing operations.

Crowdsourcing to the rescue. The power of the crowd was unlocked even more by using geoforms for filling out damage reports like bridge assessments, damaged roads, debris removal, etc. This allowed navigation apps to route around impassable areas saving time and ultimately lives. No more sending a rescue vehicle out only to find it can’t access the area because a tree is down, a bridge is collapsed, or flood waters are too high. Those delivering food could do so to where the people were.

Interactive, real-time, geospatial, command and control forever changed dispatching. Instead of waiting for teams to return before retasking them with new assignments dispatching could be of done on the fly as survivors were identified. The nearest rescue craft with available space could be routed to the exact location.

GIS allowed dispatchers to see where all the rescue teams were and how many survivors they had onboard and how many more they could take on. Data about each survivor was recorded allowing preparations for the arrival of anyone with special needs and the person’s information could immediately show up on a notification board that they had been found and rescued, important for family and friends to know.

The information also helps with forecasting needs of shelters and the reporting of numbers to those in operational authority.

Daily coordination calls were conducted over a variety of platforms with all interested and active participants. Important information was posted on a shared cloud drive. Slack, the peer to peer online collaboration platform was used so FEMA and the various groups were able to collaborate and keep the three different hurricane rescue operations segregated.

Recovery continues. The recovery efforts continue in Houston, Florida, Puerto Rico and the Virgin Islands. In efforts to increase the attention GIS played in mitigating damage from these disasters and the value of crowdsourced information FEMA hosted several events. The final event was held on Saturday, October 21, 2017. It was information about the situation on the ground in the multiple locations and the ongoing operations. It was also a celebration of the successes achieved during these crises; and, a tinge of sadness marked the event bringing to a close to some great working relationships.

If you are interested, there are still ways to get involved no matter what your skillset or expertise. If you have a desire to help, there are opportunities either on scene in the theater of operation, or remotely working from your computer at home. Check with the organizations mentioned below. Even a couple hours of your time can help.

What GIS offers next. GIS in the future of disaster response will make greater use of emerging technologies. Drones will fly preprogrammed paths ahead of a disaster if given enough time, and the imagery and the drone’s flight path will be stored. Then, immediately after the event passes drones will fly the same programmed path capturing imagery with the exact oblique and nadir angles as the original dataset.

Change detection analysis can then be used to find the exact locations of change. This method will become increasingly valuable using high resolution 3D imagery point clouds and used in a change detection system.

Geospatial artificial intelligence systems will identify the areas of greatest damage and assist by directing other resources such as mobile data signals to direct rescue operations towards possible survivors even using the last reported mobile data signal. It can direct human analysts to those specific areas that are inconclusive or require manual verification. This will increase analysis from several weeks to several days.

That is in the future, the near future, perhaps next year’s hurricane season, or tornado season, or snowstorms this winter.

This year, in total, there were 10 Atlantic hurricanes resulting in 431 deaths and an estimated $3.17 billion in damage; which by comparison, is 1/10th the number of casualties from Hurricane Katrina yet nearly twice the level of damage. It just so happens, I went through Hurricane Katrina living along the coast in Bay Saint Louis, Missouri, at the time where the eye the storm passed over. I tried to evacuate but being caught in a 13 hour traffic jam I was unable to outrun the storm. I personally experienced a category 4 hurricane. You may have picked that up in the opening of this article. Those experiences were very real. You might have also picked up my meteorological background from my days in the U.S Navy as a weather analyst.

By the end of 2017, more than hurricanes had inflicted damage. Wildfires in the western U.S. killed another 36 people and destroyed 6,000 buildings. Now, with winter upon us, there will be snowstorms, and GIS will help with those recovery efforts as well.

We are lucky to live in this day and age. Whether you are on the helping end of a disaster aiding in rescue and recovery, or on the receiving end being aided, GIS is supercharging the rescue efforts.
