While playing with the free version of Google Earth I started a list of enhancements that I’d like to see in the product. The desired outcome is to make it easier to use Google Earth as a spatial data delivery platform, without impacting on the collective end user experience.
Andrew’s writeup on Google Earth is excellent. Part 1 looks at KML and many improvements that would make using it much easier. Part 2 looks at Network Links, which at least for me has been the most confusing part of Google Earth. I guess I just don’t grab the logic of how it works, but I’m sure as time goes on Keyhole will improve it. I’m looking forward to Part 3 which should arrive later on WMS in Google Earth.
