Of course, the advantage of the TNM viewer is that you can preview the USGS Topo Map before you download it. Unless you want topo maps in Alaska, they are based on 1:100,000 and 1:24,000 scales. How to Download Historical USGS Topographic Maps with TopoView One of the neatest things ...
Recognizing the promise LiDAR holds, five years ago the United States Geological Survey (USGS) rolled out its3D Elevation Program (3DEP). The program was established by the USGS due to the growing national need for standards-based 3D representations of natural and constructed above-ground features...
By clicking on the record, you will be able to see the extent of the Sentinel scene that you want to download. To download the image, all you have to do is select the “Download” button on the right. As we are working with large data sets, you will have to be patient with downlo...
I'm downloading Lidar data from MnTOPO (http://arcgis.dnr.state.mn.us/maps/mntopo/) and want to use it to create Civil 3D sections. The Lidar data is in UTM meters and my CAD drawing is in Minnesota state plane feet. I can create surfaces using the Lidar DEM files, but I'm ...
A popular year-round tool,slope angle shadingis a visual overlay that uses a color scheme to identify slope steepness based on USGS elevation data sets, including high-resolution LIDAR data from the 3DEP program where available. Each color corresponds to a different slope angle range. For exampl...
Third parties can include mapping agencies worldwide -USGSin the USA,Ordnance Surveyin the UK,ESAin Europe and so on. These third-parties typically provide highly-accurate DEMs collected using LiDar technology. It's important to check how recently was the data collected and how has the target ...

Their maps usually use elevations from multiple sources, including the USGS and commercial satellite data. While not openly publicized, inside sources hint that Google Maps elevations are heavily dependent LiDAR readings, measured from space with a pulsed laser that can penetrate tree cover. Are We ...
