Hi, I have a large hi res globe which I've built showing 250 odd kms of river with 30cm resolution terrain and 20cm imagery - I've been asked to mod the texture so that it shows an increase in the level of the river. For small areas I typically create a contour polygon at the new water elevation and use that as a line which is baked onto the image in a 3rd party software package , this is then used in photoshop as a reference line which I can create a false texture fill inside. This process works great for small areas , unfortunately for 80 gigs of imagery I cannot manually go through each tile and photoshop a new texture for the river edge in the time allowed. I can create a georeferenced image of the new river on it's own at a higher resolution than the base image and build the globe - but then I end up with a hard edge between the base image and the new river texture - is it possible to use the osg to feather the edge of the higher res image into the existing image so that there is a smoothed edge?? I can post up some images to give you an idea of what I'm getting at if this helps. ...
Thank you!
