This dataset contains 7.1 million high-resolution ( 1m) satellite images released under CC-BY 4.0 license and made available via AWS's Open Data Registry. Static SpatioTemporal Asset Catalogs (STAC) are made up of a large number of JSON files containing GeoJSON Features annotated with metadata (STAC Items) that describe the images. Due to this storage structure, static STACs are difficult to query and, therefore, explore. For example, searching for all of the images that intersect an area of interest would require reading every single STAC Item--potentially gigabytes of data. Aggregating metadata (e.g., cloud cover, temporal coverage) would be similarly laborious. These use cases can also be onerous with a dynamic STAC API because they would require paging over results which can be slow and susceptible to request failure, rate-limiting, etc. Enter STAC GeoParquet ! Packaging STAC Items in GeoParquet format makes these tasks trivial by providing a cloud-friendly, queryable representation of a STAC Collection. tldr; Parquet is a columnar storage file format optimized for efficient storage and retrieval (querying) of large datasets GeoParquet adds interoperable geospatial types STAC GeoParquet specifies how to map STAC Items into GeoParquet format STAC GeoParquet enables efficient bulk-acc","default_branch":null,"files":null,"tree":[],"storefront":"/r/bmcandr","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/bmcandr/satellogic-earthview-stac-parquet/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
