Abstract
As a part of its AI4Earth initiative, Microsoft has created a Planetary Computer (PC) for hosting and processing open geospatial data. In addition to publishing a wide range of datasets, including Sentinel-2, MODIS, and more, the PC provides a powerful API and compute system based on open-source geospatial tools and using STAC metadata for data query, discovery, and access. In this talk, we present the latest in open geospatial data access, discovery, processing, and visualization using a variety of datasets from the Planetary Computer. We demonstrate use of the odc-stac package, which leverages the power of the OpenDataCube computing platform without the need for a database backend, and how odc-stac can load, mosaic, and transform geospatial assets into xarray datasets. We dive into other data interoperability tasks, including scaling processing with Dask and leveraging a variety of cloud-native formats. Along the way, we provide recommendations for data providers and curators on how to ensure their data can be used in a rich, interoperable way by the latest in geospatial processing tools.
