Enables you to Open almost every existing Raster (Grid) File Format.
Open, View and Calculate Files is free, so you can test your Results.
Saving a File requires SaveFile Tickets that can be bought within the app.
You can save *.asc and *.tif files. Don’t hesitate to contact us for more features.

Projections are supported but not needed if all files use the same Projection. Just place a *.prj File next to your Raster File. Use the name of your file or use one file per folder.
