I'll give the source to this app to anyone who wants it. Just give me a couple days to tweak a few things and clean it up.
I made some changes to it yesterday. Right now, you can load grids for any zone you have an in-game map for. It will show all the grids and cycle through them one at a time highlighting the selected one.
I'm going to add in a query to check for spawns along a selected grid, and give me the option to delete a complete grid if there are no spawns on it. I believe that will remove a considerable about of redundant grids.
I'm thinking about adding in some logic to merge waypoints and renumbering them automagically.
Here's one I found in Akanon that has over 600 waypoints. They're so close together, it looks like one solid line.
