The GIS Hero App is a GIS tool that makes it easy for you to download aerial imagery (i.e., NAIP, 1-m) and raster elevation data (i.e., NED, 1/9th arc seconds; roughly about 9-m pixels) and associated terrain derivatives quickly, easily, and inexpensively.
In the background:
- We fetch the individual imagery and elevation tiles from US Government Archives.
- We clip the data to your data to your specified area of interest.
- We calculate terrain and/or imagery derivatives.
- We project your data to WGS84 Web Mercator, Auxiliary Sphere.
