How to download 30 Meter SRTM elevation data?
30-Meter SRTM Tile Downloader This interface attempts to ease the pain of downloading 30-meter resolution elevation data from the Shuttle Radar Topography Mission. Click on yellow tilesto download their corresponding data.
Is there a public API for SRTM 30m?
The Open Topo Data public API lets you query SRTM 30m for free: The public API uses Version 3 of SRTM for both resolutions.
Where can I download SRTM files in Python?
Download the files from USGS into ./data/srtm30m. Before downloading you’ll need to register an account at earthdata.nasa.gov. Using these credentials for downloading is a little tricky, but luckily Earthdata provide download scripts in multiple different languages, the Python ones worked well for me.
What kind of coverage does SRTM data have?
SRTM has coverage from -60 to 60 degrees latitude. The dataset is released in 1 degree tiles. Ocean areas covered by a tile have an elevation of 0m. Open Topo Data will return null for locations not covered by a tile.
How tall is SRTM in meters and arc?
The Shuttle Radar Topography Mission (SRTM) obtained 90 meter (3 arc-second) resolution data on a near-global scale (between 56 degrees South and 60 degrees North latitude) and 30 meter (1 arc-second) resolution over United States, providing a valuable global topographic dataset.
How often does SRTM collect land surface data?
SRTM successfully collected radar data over 80% of the Earth’s land surface between 60° north and 56° south latitude with data points posted every 1 arc-second (approximately 30 meters). The level of processing and the resolution of the data will vary by SRTM data set.
What was the goal of SRTM version 3.0?
The primary goal of version 3.0 was elimination of voids in the NASA SRTM DEM. This was achieved by filling the voids with elevation data primarily from the ASTER GDEM2 (Global Digital Elevation Model Version 2) and secondarily from the USGS GMTED2010 elevation model or the USGS National Elevation Dataset (NED).
What is the resolution of SRTM void filled data?
The resolution for SRTM Void Filled data is 1 arc-second for the United States and 3 arc-seconds for global coverage.
Which is the best SRTM GL1 Elevation Dataset?
SRTM GL1 (30m Ellipsoidal) is a version of the popular Shuttle Radar Topography Mission dataset where elevation values are WGS84 ellipsoidal height as opposed to the standard orthometric, or geoid-referenced, elevation. OpenTopography constructed this dataset by subtracting the EGM96 geoid model from the standard SRTM GL1 data.
