Finally, got it to work! I was able to find the islands, placed an airfield where Wheeler should be, created the terrain, and was able to fly around in AH. A little disappointed in the elevation accuracy, but expected that. Now for the hard work: fixing the minor inaccuracies of the island shapes, improving the terrain elevations, placing more objects and airfields, etc. But, at least I got this far. Thanks to all who responded!
