Brent-- Maybe this would work for you...
1. Overlay a higher-res aerial photo of the area onto Google Earth 2. Build a model of the berm using Sketchup and place it on Google Earth 3. Overlay some landscape photos of the site onto some "background fences" built with Sketchup 4. Take some screenshots. (I used something like this to depict some fence diagrams of lithology in Google Earth.) --Roger Rayle-- [email protected] On Wed, Mar 2, 2011 at 4:13 PM, Brent Fraser <[email protected]>wrote: > To all, > > A friend of mine needs to submit a picture (rendering?) showing how a > proposed berm would look at a shooting range.
