STAC is a specification for the handling of geospatial assets. It has emerged from the efforts of several companies and organizations in the geospatial domain. In a previous article, we gave you an overview of STAC and our new storage capabilities, explaining the specification and its benefits in a nutshell. As a next step, we've published a Jupyter notebook where we further explain why we brought STAC to UP42 storage, enabling STAC-compatible endpoints for all geospatial assets in storage. The notebook, a part of a series of notebooks on the topic, will show you how to overcome common data management challenges with real-world examples.
We will first explore the API entry points and then go into the following use cases:
- Getting to the entry point for the asset service. This will inform us about the available asset catalog and which standards it conforms to
- Listing STAC collections
- Inspecting STAC items or listing a specific STAC item
- Using a unified interface to search for assets across collections
- Searching for assets that intersect a given AOI
- Visualizing the collection
- Doing complex searches for assets
- Extracting the assets ID for downloading
STAC offers an efficient and natural way to search catalogs of geospatial assets. The current implementation on top of UP42 storage provides a large degree of flexibility, making it easy to access assets using a multitude of search options. All assets are provided as hypermedia, making it simple to manipulate. Go ahead and try the UP42 Spatial Asset Service API by accessing the notebook here.
