    I can reproject them to mercator type as long as the curvature is not too great so that would be easier nearer the equator. It would not be exact (as its doing a limited power curve fit) but it would be darn close. I was asking because I tried to stitch them together as is but they would not line up exactly due to the projection and again its harder nearer the poles. So I thought before I go off and try to get them squared up into vertical and horizontal grids it might be easier to ask if you have that capability. Once its square then its easy to get the grids to match and I can see that your software is definitely doing georeffing so I can tell that its an exact match under those grid lines. Id like to see this map stitched into one large array so ill take a pop at it. Its a bit tricky but I think it can be done. Its just awesome. God knows how many hours you must have been at it.

    I have software at work that can reproject raster images, so my plan is eventually to reproject all of the maps into Plate Carree/Geographic projections and create a KML file so that they can be viewed in Google Earth as overlays. I'd like to see what you come up with too though.
    There will be some mismatches along map seams; When I start a map that overlaps another that has already been made I simply rubbersheet in the existing info and match it up quick and dirty. So there can be a little bit of error in those areas.

    That sounds very cool. I will do that shortly. My HDD decided to HDD heaven today so I am running this box now in a life support / resuscitation unit with a freshly bought HDD from the PC shop. Once im up and zipping again ill produce a short movie of it.

    Given that my little app can stretch any image in any way (to a small degree) then even if there are a few small mismatches then I can get it to warp them back in line again. The grid would then be out but hey I expect the text is going to look interesting when its warped anyway.

    Are you working in Illustrator? If so, you can at least export the line work as a dxf and then import that into ArcGIS. Edit the line work to map to an Earth projection. With a little editing it could easily become a full fledged alternate world GIS. That would be cool! Setting up a .tfw file would not be difficult at that point either. Heck, If I had the Lizartech plug in I would MrSid it for the compression. After that reprojecting becomes second nature.
