Basically determining mean values for temperature (raster), elevation (raster) for fauna observations (point buffers). Converting everything to vector and using desktop solutions proved impracticable for datasets covering the extent of Canada.

Hi,

I personally see PostGIS Raster from a developer's point of view (too
close to code problems). But taking some distance, I collaborate in
two use cases right now in my company:

- Geospatial database in the cloud. We have a big raster coverage (~
50GB) in several GeoTIFF files (~ 5-6 GB each one). We want to serve
them through a WMS interface using a cloud architecture with
PostgreSQL/PostGIS/PostGIS Raster storage. We may execute gdal2tiles
against each file and store tiles in PostGIS Raster (just a
possibility). Starting project.

- Vector/raster intersection. We want to cross public cadastral
information with a base layer of raster data (orthophotos, DEMs...) to
provide some value over the cadastral information. Useful for farmers.
Ongoing project.

More ideas welcome :-)

Best regards,
