Publishing files to a SpatioTemporal Asset Catalog¶
The SpatioTemporal Asset Catalog (STAC) specification provides an easy approach for describing geospatial assets. STAC is typically implemented for imagery and other raster data.
pygeoapi implements STAC as an geospatial file browser through the FileSystem provider, supporting any level of file/directory nesting/hierarchy.
Configuring STAC in pygeoapi is done by simply pointing the
data provider property
to the given directory and specifying allowed file types:
my-stac-resource: type: stac-collection ... providers: - type: stac name: FileSystem data: /Users/tomkralidis/Dev/data/gdps file_types: - .grib2
fiona are required for describing geospatial files.
pygeometa metadata control files¶
pygeoapi’s STAC filesystem fuctionality supports pygeometa MCF files residing
in the same directory as data files. If an MCF file is found, it will be used
as part of generating the STAC item metadata (e.g. a file named
having an associated
birds.yml file). If no MCF file is found, then
pygeometa will generate the STAC item metadata from configuration and by
reading the data’s properties.
