[postgis-users] POSTGIS DTED...

[Nick Ton]

Thanks Vincent,

I think for our low budget development we will have to take
your advice and store the DTED data externally, and do the
projection ourselves.

Is there's any push or interest for development of
raster storage and query capabilities in PostGIS?
It would seem that many data format are based on
raster format (i.e. meteorological, satellite, etc.),
and so would benefit from an open source SDE
that would support such capabilities.

I would be happy to spend some free time to support
such an effort, but I am not sure how to begin.

Thanks Again,
Nick

Nick,

Postgis has no native raster image storage capabilities.
Though there are some workarounds, like having a polygon of the raster
extent 
in a database, and a record with a link to the file name. Or to a blob with 
your image data, but then you should take care of projections, etc. etc. 
yourself.
For more info try to search this mailing list ( 
http://postgis.refractions.net/support.php ); the question you asked has 
certainly been asked before.

Regards,
Vincent Schut.
