I'm working on a project dealing with topography at a regional scale (Cincinnati region). I have imported the terrain from Google Earth. My problem is that the file size (multiple files actually as I have had to break it down into different sections) is gigantic and slow.
My question is, is there any way of either reducing detail in the terrain or reduce overlap of terrain cuts, or some other method to improve performance with the terrain? I need to eventually combine them all into a single file and it is looking impossible at the moment if I can't reduce the terrain detail.
Thanks!
