PostGIS Raster driver: Error reading Arc/Info ASCII and Binary Grid files loaded in PostGIS Raster

[jorgearevalo]

AAIGrid (ASCII): A user reported a problem. Nodata values are filled with zeros when trying to read a PostGIS Raster file with GDAL 1.7.3 released 2010/11/10 (OLD version of PostGIS Raster driver with that release).

AIG (Binary): Another user reported a different problem. When trying to execute gdal_translate (GDAL 1.7.2 from debian experimental, OLD version of PostGIS Raster driver with that release) over a .adf file loaded in PostGIS Raster, he got this error:

"ERROR 1: Can't get georeference coordinates from database (...) ERROR 1: Sorry, but couldn't create the structure to read the raster on memory, aborting."

Little patch to fix wktraster driver

About the second bug (AIG one): The problem is the driver tries to read 2 fields of raster_columns table that have changed their names (pixelsize_x and pixelsize_y now are scale_x, scale_y). So, there are 2 possible solutions:

• Recommended solution: Use a trunk GDAL version up to r20912 (new version of PostGIS Raster driver on that release)

• Apply the change in the attached patch (gdal-1.7.2-wktraster.patch) to the original 1.7.2 sources

About the first bug, doesn't happen with the new version of the driver (included in GDAL trunk on r20912).

I can't reproduce this bug. I think it works with the changes suggested in comments. I close the ticket.
