I think you should reconsider your wants ; I'd phrase it as wanting to exclude a path where any elevation > Xm. You really don't care what the highest point is, at all. > So if there is a method to exclude the > drawing of a path when any point is above the constant value it can > solve my problem. There is, but you have to write it. For each path you are thinking about drawing, get the elevations from the elevation service. Check through those elevations for > X ; if found, discard on move on to next path. If not found, draw path, and move on to next path. Note that there are limits on how fast and how many requests you can make. > In fact, I'm looking for a method to find where the path cross a part > of land. Looking for non-zero elevations will work in many cases, but its not infallible.
