Ahah! You have to add the raster table name then to the command. The Rasterlite documentation should be updated to reflect this example as it now misleadingly does not. See below... Thank you much! Examples: - Accessing a rasterlite DB with a single raster table : $ gdalinfo rasterlited

Hello all, After evaluating the Rasterlite driver and database, I've found it to be able to support everything I need except store projections for multiple rasters. I've seen hints of a Rasterlite2 driver in the works, but as of yet it's not available. I would prefer to stick with sqlite3 rather

2014-11-06 Thread Jeff McKenna
Hi all, I've successfully used the OSM driver[1] to convert from the OSM pbf binary format into another (in my case Postgres/PostGIS, and testing with Japan dataset). The time to do this is much much faster than other tools such as osm2pgsql (once I learned the "PG_USE_COPY YES" parameter th
