How to get elevation data on a map?
Click the “Help” link at the top of the page for detailed instructions on how to find and download data. There is a separate site for The National Map Services.
What are the different types of elevation datasets?
The 3D Elevation Program (3DEP) products and services available through The National Map consist of standard digital elevation models (DEMs) at various horizontal resolutions, and elevation source (lidar) and associated datasets. In 2020, Digital Elevation Models were migrated to a new data delivery format called Cloud Optimized Geotiff.
What kind of elevation data does the USGS use?
The National Elevation Dataset (NED) is the primary elevation data product produced and distributed by the USGS National 3D Elevation Program (3DEP). The NED provides seamless raster elevation data of the conterminous United States, Alaska, Hawaii, and the island territories.
Where can I find seamless elevation data for the United States?
This specification documents the requirements and standards used to produce the seamless elevation layers for The National Map of the United States. Seamless elevation data are available for the conterminous United States, Hawaii, Alaska, and the U.S. territories, in three different resolutions—1/3-arc-second, 1-arc-second, and 2-arc-second.
Can a legacy software read an elevation file?
Legacy software can read the file with no additional modifications because the underlying file format is a geotiff. Standard elevation products are available in the following resolutions and formats: Where can I get global elevation data? What is Lidar data and where can I download it?
Where can I get USGS 3D elevation data?
The USGS 3D Elevation Program (3DEP) is excited to announce the availability of a new way to access and process lidar point cloud data from the 3DEP repository. The USGS 3D Elevation Program (3DEP) announces the availability of a new dynamic map service.
