I knew that the iPhone had an app called "Dude, Where's My Car?" which let someone use GPS to tag a specific location and then later use Google Maps to guide them back to the GPS mark, but when I did some searching I couldn't find a WinMo version. So I made one.
This version isn't as sexy as the iPhone app, but it's free, and you can store up to 3 different locations and even name them if you'd like. When you want to locate one, you just click the respective Find button and you will be provided an arrow or compass direction (N, NW, S, SW, E, SE, W, NE) and approximate distance to your destination which will change as you continue to move.
I did some testing and got rid of whatever bugs I could find and everything seems to work. Since I find it useful to have, I wanted to pass it on to the community in case they might be interested as well.
If you find any problems with it, let me know, otherwise enjoy.
I finally got around to adding arrow guidance to accompany compass directions for finding a destination. The arrows are a bit finicky, but its partially due to the quality of the gps fix and the amount of fluctuation in the coordinates it gets. I find that the best way to work with it is to travel in one direction for a short distance steadily until a steady arrow appears. Once that happens, turn in the direction of the arrow and keep walking in the direction it had indicated until it changes to reflect the direction you turned. I.e. if you are walking straight and right arrow appears, turn right and keep walking straight until the right arrow changes to an up arrow.
I also updated the source code package for anyone interested in modifying the code. As before, I just ask that you keep its open nature going (GNU style) and if you post a new version of the software with arrows, or a better GPS interface (that uses triangulation as an option), etc. that you link the new software back to this thread and you let me know about it so I can check it out
As requested, I have attached the source code for the project developed with Visual Studio 08. It's not super clean since I put it together kind of rapidly, but it is decently commented. Anyone is welcome to modify this code and use it for your own personal development. Enjoy and let me know if you have any questions.
Attached a screenshot from my visual studio emulator. It should look the same as on the phone but with longer decimal values for the GPS coords.
Also attached the .cab files for the .NET framework that people were having issues with. I don't know if those will resolve the problems or not, but I developed the phone using the 3.5 compact framework. If you have that, a GPS chip on your phone, and WinMo 6 it should work for you.
