PostGIS Cookbook - Second Edition

Warping and resampling rasters

In the previous recipe, we processed a MODIS raster to extract only those subdatasets that are of interest, in a more suitable order. Once done with the extraction, we imported the MODIS raster into its own table.

Here, we make use of the warping capabilities provided in PostGIS. This ranges from simply transforming the MODIS raster to a more suitable projection, to creating an overview by resampling the pixel size.
