...as opposed to keeping the rasters as locally stored GEOTIFFs?
I have a large project that will require making available approximetely 50,000, 10mb GEOTIFFs as WMS to an OpenLayers based web map. Only 1 WMS will be displayed at any given time so performance is a non-issue. Considering MapServer and GeoServer for this application.
I would like to know what are the advantages and disadvantages of storing this type of data. Will updating a PostGIS database when the raster data changes be more difficult, rather than replacing a single (or series of) raster files. WMS load times drastically improved with PostGIS?
