Global geographic elevation data made easy. elevation provides easy download, cache and access of the global datasets SRTMGL1 30m Global 1 arc second V003 elaborated by NASA and NGA and SRTM 90m Digital Elevation Database v4.1 elaborated by CGIAR-CSI.
Install the latest version of elevation from the Python Package Index:
$ pip install elevation
The following dependencies need to be installed and working:
The following command runs some basic checks and reports common issues:
$ eio selfcheck
Identify the geographic bounds of the area of interest and fetch the DEM with the eio command.
For example to clip the SRTMGL1 30m DEM of the area of Rome, around 42N 12.5W, to the Rome-DEM.tif file:
$ eio clip -o Rome-DEM.tif --bounds 12 41.5 13 42.5
The --bounds option must be given as left bottom right top similarly to the rio command form rasterio.
The first time an area is accessed elevation downloads the data tiles from the USGS or CGIAR-CSI servers and caches them in GeoTiff compressed formats, subsequent accesses to the same and nearby areas are much faster.
It is possible to pre-populate the cache for an area, for example to seed the SRTM3 90m DEM of Italy execute:
$ eio seed --product SRTM3 --bounds 6.6 36.6 18.6 47.1
Every command have a corresponding API function in the elevation module:
import elevation # clip the SRTMGL1 30m DEM of the area around Rome and save it to Rome-DEM.tif elevation.clip(bounds=(12, 41.5, 13, 42.5), output='Rome-DEM.tif') # seed the SRTM3 90m DEM of Italy elevation.seed(product='SRTM3', bounds=(6.6 36.6 18.6 47.1))
