Aggregate methods for Raster Data in django.contrib.gis.db.models

[Juan Escamilla]

Dear All,

I'm working with raster data in Postgis using Django models as the connector.

I've found that the lookups for raster are not efficient (uses ST_Polygon for making the intersection).

Also, I need to aggregate some data or extract the value in a x,y, coordinate.

Do you have any ideas for improving these features. I have some code (Aggregates) that may be useful for you.

Thank you for reading

Best wishes,

Juan.

p.s. I'm working with the stable branch in github    '1.11.dev20160704203858'
