Ticket #1440 (closed enhancement: fixed)
[raster] Support for reading offline band data
|Reported by:||dustymugs||Owned by:||dustymugs|
Add functionality to load offline bands so that the PostGIS raster functions can be used. The data will be read-only instead of read-write due to several issues:
1. filesystem privileges: will the user account that the postgres process have write access to the raster file and containing directory?
2. offline raster format: does the format of the offline raster permit direct modification of a band value or is an intermediary format required?
Once read-only access is complete, the out_db column of raster_columns view will be reintroduced. In the new iteration of the out_db column, it will be an array of booleans where each element indicates that the band's data is offline.
