About the `"raw_polygon"` field in metadata files #11

Closed bourcierj closed 10 months ago

bourcierj commented 1 year ago

Hello, AFAIK, there are some fields in the metadata files that are not documented, such as the "raw_polygon" field.

Is this supposed to be the polygon enclosing the image, with geospatial coordinates ? What is the syntax of the value of this field ? Is it possible to convert it to a GeoJSON ?

Thanks

I've checked for myself and this is indeed the footprint of the whole image. Coord system is WGS84 and syntax is WKT, which can be easily read by shapely.
