stactools-nrcan-spot-ortho

A subpackage of stactools for working with orthorectified SPOT 4 and 5 data over Canada.

This subpackage converts the Geobase Index shapefile, that describes the orthorectified SPOT 4 and 5 image extents, to a STAC catalog.

Usage:

stac nrcan-spot-ortho convert-index [index location] [root_href]

The root href can be a local or S3 path. The default catalog type is pystac.CatalogType.ABSOLUTE_PUBLISHED.

The STAC catalog created contains assets with hrefs pointing to zipped imagery on the Geobase FTP. These can be be downloaded, unzipped and converted to COGs with:

stac nrcan-spot-ortho cogify-assets [catalog path] -d [COG directory]

By default the COGs will be written into the same directory's as their respective STAC items, and will not overwrite existing COGs (use --overwrite to do so). The STAC will be updated with the COG assets during this process.

A complete orthorectified SPOT 4 and 5 STAC, including COGs, can be found here.
