Imagine you are a city official who wants to ensure all future infrastructure and urban development in your city is climate- and disaster-sensitive. The first step is to understand the natural hazards of today and tomorrow—flood, storm surge, sea level rise, etc.—and how they could impact your city. Thanks to higher-resolution geospatial datasets released this week by the U.S. Government, you will now be able to have a better understanding of the risks your city faces and how to manage them.
These newly available Digital Elevation Models (DEMs) were developed by the U.S. Government and detail the surface of the earth in 3D. By illustrating the geography and topography of an area, they enable users to quantify the potential destructive impact of water-related hazards. As a city official, you will be able to base your analyses on 3D maps showing the natural terrain and elevation of your city, which determine the path of the water.
