Topography is a Python library for fetchin … Topography is a Python library for fetching and caching land elevation data using the OpenTopography REST API. Topography provides access to the following global raster datasets:</br></br>* SRTMGL3 (SRTM GL3 90m)</br>* SRTMGL1 (SRTM GL1 30m)</br>* SRTMGL1_E (SRTM GL1 Ellipsoidal 30m)</br>* AW3D30 (ALOS World 3D 30m)</br>* AW3D30_E (ALOS World 3D Ellipsoidal, 30m)</br>* SRTM15Plus (Global Bathymetry SRTM15+ V2.1)</br>* NASADEM (NASADEM Global DEM)</br>* COP30 (Copernicus Global DSM 30m)</br>* COP90 (Copernicus Global DSM 90m)</br>* EU_DTM (DTM 30m)</br>* GEDI_L3 (DTM 1000m)</br>* GEBCOIceTopo (Global Bathymetry 500m)</br>* GEBCOSubIceTopo (Global Bathymetry 500m)</br>* CA_MRDEM_DSM (DSM 30m)</br>* CA_MRDEM_DTM (DTM 30m)</br></br>as well as these USGS 3DEP raster datasets:</br></br>* USGS30m</br>* USGS10m</br>* USGS1m </br></br>The library includes an API, CLI, and BMI that accept the dataset type, a latitude-longitude bounding box, and the output file format. Data are downloaded from OpenTopography and cached locally. The cache is checked before downloading new data. Data from a cached file can optionally be loaded into an xarray DataArray using the experimental open_rasterio method.</br></br>More information on Topography can found in its documentation: https://bmi-topography.readthedocs.io.on: https://bmi-topography.readthedocs.io. +
