|LabDescription=<p>GeoTiff is a Python library for accessing data and metadata from a GeoTIFF file through an API or a BMI.</p>
<p>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.</p>
<p>More information on GeoTiff can found in its documentation: https://bmi-geotiff.readthedocs.io.</p>

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
Use an application programming interface (API) for a Python library
Use a Basic Model Interface (BMI)
Key concepts
Access data through a data component
Understand the difference between an API and a BMI, as well as their relative strengths
