Sentinel-1 RTC Geometry Footprint Incorrect Over Antimeridian #465

Description

@alexgleith

Some items, like this one, have incorrect geometry and bbox values.

https://planetarycomputer.microsoft.com/api/stac/v1/collections/sentinel-1-rtc/items/S1A_IW_GRDH_1SDV_20240120T173231_20240120T173300_052193_064F2B_rtc

The bbox is:

[-181.35806879548392,
 -17.964499988214673,
 -178.6353346846058,
 -15.810469709413946]

and the geometry is:

{'type': 'Polygon',
 'coordinates': [[[-178.9158366078743, -17.392467454843494],
   [-178.6353346846058, -16.21938807791095],
   [-179.4155417444812, -16.041120376553458],
   [-179.43106638466193, -16.10408838729522],
   [-180.22893359283418, -15.918458849489095],
   [-180.24357930907945, -15.976289613558276],
   [-180.9446388233092, -15.810469709413946],
   [-181.35806879548392, -17.428073423615142],
   [-179.0617565335933, -17.964499988214673],
   [-178.9158366078743, -17.392467454843494]]]}

Note that for this to be valid, the bbox should hold values that are within the range -180 - 180 and the geometry should be split across the antimeridian (so it's a multi-polygon).

For a good example of this, see this Item.
