Topic: It appears your asset store page is misleading
I almost bought Real World Terrain because I was under the impression that you have heightmap resolutions of .25 meters, due to the way its written on the Asset Store.
Here on your webpage it is a lot clearer that those are actually just satellite images, and Bing is your best heightmap resolution at 10 meters.
Elevation Heightmaps:
Bing Maps resolution of max 10 meter per pixel.
SRTM v4.1 resolution of 90 meters per pixel.
Satellite images resolution of max 0.25 meter per pixel.
The indentation doesn't come across on the Asset store. I would suggest moving that last line to a totally different part of the description so you don't have people angry that their heightmaps aren't good enough.
Unless I'm mistaken and you really DO have .25 meter heightmap resolution, in which case I'll buy immidiately.
Take care
