PostGISRaster --- PostGIS Raster driver

The fact that PostGIS raster provides you with SQL functions to render rasters in known image formats gives you a lot of optoins for rendering them. Create a table with a raster column. If no projection algorithm is specified, NearestNeighbor is used by default.

Also available are VS project files. This will always read the current database.

You can get rid of that folder. Is the syntax incorrect?

Note If you omit the name of the schema and use demelevation instead of public. For teh spatial idnexes to work properly you'll need to drop those and replace with convex hull based index. To optimize query performance for the raster table, create a spatial index on the raster column. Sign up using Email and Password. Table of Contents 5.
