----------------------------------------
Summary: Implement RS_Intersects(raster, geom)
Key: SEDONA-321
URL: https://issues.apache.org/jira/browse/SEDONA-321
Project: Apache Sedona
Issue Type: New Feature
Reporter: Kristin Cowalcijk
RS_Intersects(raster, geom) Returns true if the envelope of the raster
intersects the given geometry. If the geometry does not have a defined SRID, it
is considered to be in the same CRS with the raster. If the geometry has a
defined SRID, the geometry will be transformed to the CRS of the raster before
the intersection test.
{{RS_Intersects}} is for easier fetching rasters in the region of interest from
a dataframe containing rasters in various coordinate reference systems.
{{RS_Intersects}} is deliberately defined differently from [ST_Intersects in
PostGIS|https://postgis.net/docs/RT_ST_Intersects.html] for the following
reasons:
# {{RS_Intersects}} performs implicit CRS transformations, which has a
different semantics from {{ST_Intersects}} in PostGIS
# {{RS_Intersects}} uses the envelope of rasters rather than the convex hull.
We may switch to use convex hull once we find an easy way to compute the
footprint of grid coverage using GeoTools.
