Thanks for the quick reply Greg. I did read somewhere that Google has severe restrictions on the use of their maps but the Google map is the only accurate on-line map that I can find. > The notion that OSM's map is 15 years old is odd, as the project is only > about 6 years old. It could be that OSM contains data from your local > government I'm sure that's true. The Local Government office were still handing out old maps to tourists two years ago. They must have exhausted their supply of old maps and now they have a stock of new maps but they're not as complete as the Google map.

That looked like a complicated task as well but I might have another look at it. > As for easting and northing: viking can use "web mercator", which isn't > really mercator, but is what google and other webmaps (including osm) > use for tiles.

I installed proj4 but I couldn't relate what I wanted to do with the application's instructions. Perhaps proj and proj4 are not one and the same? > Do you know the datum and projection of your local map? No, but suppose I had a screen grab of the Google map, how would I proceed? By the way, the Bird's Eye map looks to be about the same vintage as the Open Street map. -- Regards, Phil ------------------------------------------------------------------------------ Everyone hates slow websites.
