Looks like they don’t provide the data from that service just the extents. To get the data, they have the product view https://viewer.nationalmap.gov/basic/#productGroupSearch
that links to files for download Or you can access them directly via gdal with something like gdalinfo /vsizip//vsicurl/https://prd-tnm.s3.amazonaws.com/StagedProducts/Elevation/1/GridFloat/USGS_NED_1_n35w117_GridFloat.zip/usgs_ned_1_n35w117_gridfloat.flt Mike -- Michael Smith US Army Corps of Engineers Remote Sensing/GIS Center From: Carl Godkin <cgod...@gmail.com> Date: Thursday, June 4, 2020 at 10:28 AM To: <michael.smith.e...@gmail.com> Cc: <gdal-dev@lists.osgeo.org> Subject: Re: [gdal-dev] Using GDAL WMS with USGS 3DEPElevationIndex Hi Michael, Thanks a lot for your reply. I managed to come up with something sort of like that by using gdal_translate to a WMS service description file and then using that. But I don't see how to get elevations from there. Have you figured that out? I know how to get imagery, but I'm interested in elevation values.

Starting here: https://index.nationalmap.gov/arcgis/rest/services/3DEPElevationIndex/MapServer it would seem to be possible but I just cannot get anything back other than solid white images. Most of the help from that page leads off to ArcGIS-land which I don't have or want to use. And Googling for 3DEP leads only to more government sites that aren't helpful. If you have some experience with this (or a related public elevation data source), would you please send an example "gdal_translate" command line? I'd really like to figure out how to download terrain (as perhaps a GeoTIFF with floating point elevations) for an arbitrary CONUS lat/lon range.
