[postgis-devel] Is it planned that overview rasters of PostGIS rasters can be registered outside the database instead of inside

[Regina Obe]

Pascal,

 

Not to my knowledge.  Are you proposing that raster2pgsql would generate the
overviews outside of the database and then register what it generated?

The issue I see with that is then it would need to decide what format to
store these overviews because the postgis raster format can’t exist outside
of the database.

A more common request is referencing overviews that are already built.  Many
external raster already have such a functionality.  I think that’s a bit
more involved though.

 

Thanks,

Regina

Dear PostGIS-Developer

With the raster2pgsql tool also overviews of the rasters can be loaded into
the database. It should be possible to register these overviews outside the
database instead of loading them into the database. The problem is that
rasters with high resolutions (2m, 0.1m) need a lot of space for the
overviews. Is there any development ongoing or planned in this regard?

 

Kind regards
