[postgis-users] A PostGIS-Raster data proposal

[Guido Lemoine]

My little bit:

- I came across the JasPer package at 
http://www.ece.uvic.ca/~mdadams/jasper/
  recently (JPEG-2000 codec in C) . I have only had a brief look at it. 
It is mentioned
  there that it is included in GDAL. The site states it is Open Source, 
but the license
  does not look familiar.

- I use JAI (Java Advanced Imaging), which can read and write JPEG2000. 
JAI contains
  all the operators for image subsampling, ROI extraction etc.

But for the moment, I am happy with storing metadata in Postgis and do 
the specific
processing externally (using JAI and JDBC) with image data on disk. 
Still, I like the
pgraster idea, as it is probably useful in the JAI/JDBC context as well.
