There is a wealth of freely available geographical data (especially topographic data) on the internet, mostly derived from satellite missions. Using freely available software, this data can be compiled into forms readily usable by consumer GPS receivers such as those created by Garmin.
I created this web-site initially to share a topographic map of Malaysia (based on SRTM v2) which I compiled for my own Garmin GPSr for use during a short mountain climbing trip to Sarawak.
I intend to create an updated version of this map based on SRTM v4 and to expand its coverage to include the whole of South East Asia. I'm also working on seeing if any useful maps can be created from hydrological and land use satellite data.
This site is dedicated to people who enjoy the great outdoors.
