Description
The FetchSRTM tool downloads SRTM and NED terrain data. The tool allows the user to batch download larger areas, then saves and decompresses the data to a user defined location.
The tool can be downloaded at https://www.pathloss.net/fssetup.exe
How To use the tool
- Click Set directory to set the location of the downloaded files. This is the location where the program will decompress and save the files
- Enter the bounding coordinates of the area of interest. The graphic below shows an example of how to read the bounding coordinates from the Pathloss Network grid. The coordinates are entered as whole numbers (no decimal or minutes and seconds) Be sure to use negative values in the western and southern hemispheres.
- Select the Data type you want to download. The USGS 1/3" NED files are large and can a long time to download
- Click Fetch to start the download.
- If you have selected 1" SRTM as the data type, you will be prompted to enter your Earthdata login credentials. A cookie will be stored and subsequent downloads will not require the login. The FetchSRTM tool does not store your Earthdata user name or password.
- The download will begin and download progress is displayed. Previously downloaded data will not be overwritten, these files are skipped.
- The files will be automatically unzipped and saved in the directory that was selected.
- NED 1/3" files are large and can take considerable time to download.
- NLCD files require post processing and can take a considerable amount of time to download and convert.
