Python library to get elevation data
pyhigh is a Python package for accessing elevation data, which is retrieved from a USGS dataset. The package uses caching to avoid unecessary downloads from the USGS dataset, but please respect their download policies.
> pip install pyhigh
pyhigh Python package includes a command-line tool of the same name to retreive the elevation at a particular latitude and longitude:
> pyhigh --lat 36.52011 --lon -118.671 1884
As necessary, files will be download from a USGS dataset and cache in the folder
pyhigh/pyhigh/.cache. To clear this cache, use the
> pyhigh --clean
get_elevation function returns the elevation, in meters, at the given latitude and longitude.
>>> from pyhigh import get_elevation >>> get_elevation(lat=36.52011, lon=-118.671) 1884
It is also possible to request a bunch elevations for a bunch of latitudes and longitudes at once. The result returned is a NumPy array of elevations.
>>> from pyhigh import get_elevation_batch >>> get_elevation_batch([(36.52011, -118.671), ... (36.62011, -118.771)]) array([1884., 2438.])
This is more efficient than individual calls to
get_elevation because elevation reads are pooled together to avoid reading the same
*.hgt file multiple times.
pyhigh cache of
*.hgt files can be cleared with the API function
>>> from pyhigh import clear_cache >>> clear_cache()
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
