Great Britian Ordance Survey Raster Maps

May 12, 2012 at 5:10 PM

Visual studio VB 2010 MapWinGis ocx.   I want to load and find location (Lat/Lon) on Great Britian Ordance Survey Raster Maps.  The map ars suplied with a .tif file (raster) .tfw (world file) .tab (table file).   Any sample code or information on how to load these.
I can load the raster file ok but how do I set it up to read the projection which appear to be in the .tab file.

Sample .tfw file
1.000000000000000
0.000000000000000
0.000000000000000
-1.000000000000000
335000.500000000000000
309999.500000000000000

Sample .tab file

!table
!version 300
!charset WindowsLatin1
