This is a Python package designed for terrain data fetching.
To install the package, simply use pip: $ pip install pyterrain
Pyterrain itself does not provide terrain data. Instead, it retrieves data from an external source. In order to download this data, you first need to register for an API key at nextzen.org. An example of the key format would be Dto0r88DQuaQizoxcQSxxx.
Once your API key is set up, you can proceed to download DEM data as follows:
bbox = 116.972979,36.387619, 117.208694,36.172087 # This represents the Mount Taishan of China
terrain = Terrain("Dto0r88DQuaQizoxcQSxxx") # Insert your API key
xs, ys, elevation = terrain.fetch(bbox=bbox, quiet=False, coord="lonlat", zoom=10)In case the download isn't completed due to connectivity issues, please retry the process.
