The ASCII Grid format is supported for import and export, and is always represented as a single 16-bit signed raster layer. It is likely that floating point grid files will not work.
If a ``.prj'' file is in the same directory as the grid file, and has the same basename as the grid file it will be read to obtain projection information. Currently the only recognized projection is UTM. All other files will be imported with a MAPUNITS string of ``METRE''.
Is is not possible to LINK to Grid files as they are ASCII encoded.
Export of Arc/Info ASCII Grid files is supported. These files are exported with a type of "GRD".
All grid files are written out as a single 16 bit signed raster layer. Grid files should be read into Arc/Info with the ASCIIGRID command.
No other data types can be exported to a grid file. Georeferencing coordinates are written to the file, but the georeferencing system is not. That is, .prj files are not produced.
