---------------------------------------
Summary: Add raster type to Sedona
Key: SEDONA-251
URL: https://issues.apache.org/jira/browse/SEDONA-251
Project: Apache Sedona
Issue Type: Improvement
Reporter: Martin Andersson
Adding a raster type would enable a lot of use cases.
A raster has grid values, an evelope, a coorinate referens system and other
metadata.
The current raster functions operate on arrays of doubles. The metadata is kept
in separate columns created by the custom data source for geotiff. That is
making rasters unnecessary hard to work with. A raster type would close the gap
between Sedona and other raster SQL implementations like Postgis.
