Welcome

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.

Land Usage

Still working on seeing how useful information can be extracted from the Global Land Survey. GLS 2000 seems to have the best coverage for Malaysia.

Rivers

The following .img file contains rivers which are calculated to exist based on topographic information as derived from http://hydrosheds.cr.usgs.gov

Whole of South East Asia (15 arc-second resolution, approx 500m) http://three15.org/topo/Rivers/90100010.img

SRTM v4

These series of topographic maps were compiled to be fairly compatible with the Malfreemaps road maps. It is basically bigger and more cluttered than Antyong's edition.
* Topographic lines below 100m are included
* I think it is more detailed, although only marginally so
* There are more tiles (this is because I can't get cgpsmapper to create .img files larger than 16Mb).
I guess it won't suit the typical road user - I've made it for people who just want all the detail possible and are not concerned with maps size and clutter.

SRTM v2

This is a compilation of publicly available topographic data compiled into a format compatible with most Garmin GPS receivers.

Coverage

The East Malaysia map covers the whole of Sabah, Sarawak, Labuan and Brunei and a small portion of Kalimantan (approximately N0.75 E109.5 - N7.55 E119.5)
The West Malaysia map covers the whole of Peninsular Malaysia and Singapore with a bit of Thailand and Sumatra (approximately N1.1 E99.5 - N6.8 E104.4)
