One-line model description A CSDMS data component used to fetch and cache NASA Shuttle Radar Topography Mission (SRTM) land elevation data using the OpenTopography REST API.
Extended model description Topography is a Python library to fetch and cache NASA Shuttle Radar Topography Mission (SRTM) land elevation data using the OpenTopography REST API.

The Topography library provides access to the following global raster datasets:

  • SRTM GL3 (90m)
  • SRTM GL1 (30m)
  • SRTM GL1 (Ellipsoidal)

The library includes an API and CLI that accept the dataset type, a latitude-longiture 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.

Memory requirements Data are downloaded directly to a file, so memory use is minimal. Optionally, the data can be loaded into a Python session, in which case, memory use scales with the size of the data.
