The Grid Builder dialog is invoked from a starting waypoint – select a waypoint on the map, right-click, and click Grid Builder. Since this feature sounded a lot like the Project Waypoint command in ExpertGPS, I used that dialog as the starting point for designing the Grid Builder dialog. He can then connect some of those points into routes for his GPS to guide him through the forest and ensure that he stays on track when he’s on his timber cruise. What Dennis needs is a way to create a grid of waypoints at regular intervals. They can then extrapolate the counts they collect on their survey walk to estimate the total board-feet of timber in the parcel. Rather than count every tree in a parcel, foresters typically create a grid of regularly-spaced points, a “fishnet grid”, that covers the tract, and then walk a line that visits a percentage of these points (say 10%). I’ve been exchanging emails with Dennis G., an ExpertGPS user who is using the software to prepare “timber cruises” on tracts of forest land.
