I noticed this after i installed a landlcass update of Phoenix i made with landclass assistant. It surrounds the entire state of Arizona. I have seen it on flights to Ca and Mex. Any Ideas. Its the straightest river ive ever seen hehehttp://www.fsworldonline.com/~rgrayal/signature.jpg

It's because you chose an area of 256x256. Use 257x257 instead. Otherwise, you can recalculate the x and y cell. The formula is degrees / (cells - 1), not degrees / cells. That'll fix it.Cheers, Christian

Actually, I've had a new .inf file out since mid-June which corrects this. It is available here at Avsim. While the other response is correct, the formula is dependent on the .raw file size used.... I use 256x256 for my .raw file size in Landclass Assistant... DL the new .inf file, and place it in your Landclass Assistant program folder...-John
