Is there anyone who can help with creating a map for this purpose? It will have to be something more than just a Garmin map file -- I'm thinking maybe something drawn in Illustrator or something similar. Contour lines should be included, and shading of the terrain would also be useful.
I can provide tracklog data for the trails, although we might need to collect further data for some of the geophysical features (like the lake, although this can be obtained from googlemaps).
I personally congrats you for your effort in tracking trails for lakes, forest etc. As you know, some of the garmin users use garmin PND (like you I guess) as a guide for climbing mountain and hiking.
For this purpose, we also welcome your tracklog (we map more than just for drivers.. hahaha) and probably, who know, your effort will be used by many people who wants to feel malaysian forest/lakes adventures or as a benchmark should any illegal logging happens in that areas without noticed by the relevent auth...
