http://www.gdal.org/frmt_various.html#WLD Google("tfw tif") should yield lots of examples Being new to GIS you will probably need to study a bit :-) This is a decent general introduction http://www.colorado.edu/geography/gcraft/contents.html Here is a gentle intro to 'projections' http://www.colorado.edu/geography/gcraft/notes/mapproj/mapproj.html Here is an overview of a popular OpenSource programing implementation of the GIS 'raster' data model. eg maps and 'photos' http://www.gdal.org/gdal_datamodel.html HTH Norman
