Hey gang, Glad it worked for you Bruce & Mike. Wow Bruce 500 point markers, that took a few minutes.   Scott & Perry Navigate to your lot. zoom in so you can see lot boundary lines. Place about 100 + markers over your lot or area. Chief extrapolates the contours better with more points. Then export the waypoints. Then import the gpx file into chief using the gps import function. Rebuild terrain and presto!    Here is a file that I made about 220 or so points. It is in Steamboat CO.     waypoints (1).zip
