I'm trying to find out what the formula would be to convert the X, Y of an image to the Easting and Northing coordinates.
I've downloaded some of the raster maps from OS UK web site and I'm looking at adding the miniscale tif file to one of my applications. I've been given a number of coordinates in the easting northing format and I need to convert this to an x y of the image so I can place a label or image on top of the mini scale tif file.
I've been searching online quite a bit but everything seems to point towards applications like ArcGIS and other GIS software. However I'd quite like to make this a simple project, so I'd like to avoid embedding 3rd party sources within the application.
Does any body have any good starter guides or examples on this, or what the forumla would be to work out the x y from the easting and northing I have?
