Ensure proper handling of geometries passed in that cross the antimeridian #261

Open bitner opened 7 months ago

j08lue commented 7 months ago

On the NASA IMPACT VEDA project, we are submitting STAC queries against STAC-FastAPI with the PgSTAC backend (details in our infra project: https://github.com/NASA-IMPACT/veda-backend).

Some of the queries fail, in particular with a complex MultiPolygon for Alaska and we have a suspicion that it has to do with parts of that MultiPolygon crossing the antimeridian.

It is only a suspicion for now, though, and we need to make some tests to get to the real cause of the issue.

Please see the details on the upstream issue description:

EDIT: to close the circle on this - the issue turned out to be request payload limitation, not antimeridian.

Just swinging by to drop a shameless plug for https://github.com/gadomski/antimeridian/ to correct geometries on the way in.
