Re: [gdal-dev] Gdal GeoTIFFs in MapInfo

Problems: 1) MapInfo can't handle compressed overviews ( *--config COMPRESS_OVERVIEW DEFLATE*) - I can easily get past this one by not compressing them. 2) However, my next problem is that MapInfo can't read the projection information from within the file. Is GDAL capable of creating a TAB file? Not currently. It can read them, and it is used in a few drivers such as GTiff. Writing is done only in the MapInfo TAB driver for the vector part. The writing of .tab for raster files would only be a matter of implementing it... 3) Finally, while MapInfo will happily open my small subset sample (above issues not withstanding), it won't load my full image (about 2GB).

Re: [gdal-dev] Gdal GeoTIFFs in MapInfo
Hi Even, Well, I don't know MapInfo limits with raster files. Perhaps is it just big raster dimensions that cause problem, or tiling, or .. ? I guess it's size. I've tried with no compression, no tiles, and both no compression or tiling, all fail. So I guess a MapInfo thing then.

Re: [gdal-dev] Gdal GeoTIFFs in MapInfo
What about using a world file for the projection info? It is an Esri thing, but maybe MapInfo will recognize it. Just add a -co TFW=YES to the gdal_translate command.

Just add a -co TFW=YES to the gdal_translate command. I may remember wrong and I do not have Mapinfo at hands now, but I bet that it at least used to be so that you first _import_ GeoTIFFs with Mapinfo and it creates a tab file. Later you can _open_ the tab. If that fails it may mean that Mapinfo does not recognize the projection of the GeoTIFF. -Jukka Rahkonen- ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
