    * polygonize with GDAL or GRASS, that generates some internal structure for those libraries, and you turn that into a WKT form of polygon. That can be passed to PostGIS, and you don't need to link to liblwgeom.[[BR]][[BR]]
  1. Best practice for band referencing: having a band parameter (index?) or always use RT_Band()[[BR]][[BR]]-e.g. SELECT RT_AsTIFF(RT_Band(raster,2),60) FROM coverandtemp[[BR]][[BR]]SELECT RT_AsTIFF(RT_Band(raster,2),RT_Band(raster,1),60) FROM coverandtemp[[BR]]or[[BR]]SELECT RT_AsTIFF(raster,2,60) FROM coverandtemp[[BR]][[BR]]Pierre: Having a band parameter (or a list of band) for each function trying to access a band would be preferable to avoid useless memcopy of band data.[[BR]][[BR]]

    * Describe key terms: canonical format, serialized format, transfer format (WKB), in-db raster, out-db raster, etc. This should help people to grasp the WKT Raster key elements quickly, and help them to decide which document/RFC to read in details.[[BR]][[BR]]
