GeoTiff is a Python library for accessing data and metadata from a GeoTIFF file through an API or a BMI.
The bmi-geotiff library accepts a filepath or an URL to a GeoTIFF file. Data are loaded into an xarray DataArray using the experimental open_rasterio method. The API is wrapped with a Basic Model Interface (BMI), which provides a standard set of functions for coupling with data or models that also expose a BMI.
Classroom organization This lab includes examples of using the GeoTiff data component in a Jupyter Notebook, in a shell script, and in a Python program. Try editing these examples to download, open, and display data from other GeoTIFF files.
Learning objectives Skills
