ASTER GDEM Thailand v1.02

This is an update of ASTER-GDEM Thailand v1.00. The main changes are compatibility with more recent versions of Mapsource and incorporation of GSHHS v2 (coastlines) and HydroSHEDS rivers.

Coverage: The whole of Thailand (tiles bordering Malaysia can be obtained from the Malaysia map) and Cambodia; most of Laos and Vietnam (excluding the Northern most parts); portions of Myanmar (up to Mandalay as the north-western most tile covered). Includes these cities: Rangoon, Phnom Penh, Hanoi, Ho Chi Minh city and Vientiane, and Bangkok, of course.

Approx: N4-21 E96-108

This was updated 31 May 2010: Removal of Sumatra and addition of the Vietnam 'bulge'

ASTER GDEM Malaysia v1.02

This is an update of ASTER-GDEM Malaysia v1.01. The main changes are compatibility with more recent versions of Mapsource and incorporation of GSHHS v2 (coastlines) and HydroSHEDS rivers.

I believe this is the most detailed freely available topographic map of Malaysia available. It is best used combined with other (road) maps.

Coverage: The whole of Malaysia, Singapore and Brunei

SRTM South East Asia v4.02

This is an update of SRTM South East Asia v4. The main changes are compatibility with more recent versions of Mapsource and incorporation of GSHHS v2 (coastlines).

ASTER GDEM UK and Ireland v1.00

Coverage: UK and Ireland; and a bit of France

ASTER GDEM Thailand v1.00

Made a discovery which enabled me to automate the map compilation process hence I managed to produce this map quite painlessly

Coverage: The whole of Thailand; most of Laos and Cambodia; portions of China, Myanmar, Vietnam, Malaysia and Indonesia. Includes these cities: Rangoon, Phnom Penh, Hanoi, Ho Chi Minh city and Vientiane, and Bangkok, of course. Approx: N4 E96 to N21 E108.

Thailand is coming very soon

Managed to figure out a way of making the map as a batch. So I managed to compile all 161 tiles of the up and coming Thailand map with very little user intervention but a lot of computing time - seven days just to vectorise the data, for example. This Thailand map also includes substantial bits of the surrounding the countries - for example it includes these cities: Rangoon, Phnom Penh, Hanoi, Ho Chi Minh city and Vientiane.

It's huge - 1Gb.

SRTM South East Asia v4

Have been inspired by Malfreemaps' recent push into covering ASEAN countries. Hope this map will support it.

In order to expand coverage to an entire region, I have had to compromise on detail. Contour lines are only at 50m intervals. I choose not to use the ASTER GDEM as detail is not so crucial and furthermore, there are some distorted patches in the ASTER GDEM.

Coverage: Most of South East Asia (A rectangular block from S15 to N25, E91 to E145). This fairly large block includes parts of India and Bangladesh at the Northwest corner, Guam, Taiwan and Hainan Islands at the Northeast, and Northern Australia (including Darwin). Major omissions include the Northern mountains of Myanmar and Eastern Papua New Guinea.

ASTER GDEM Malaysia v1.00

Malaysia, Singapore, Brunei and portions of Kalimantan and Sumatra

This is my first attempt at compiling the ASTER GDEM. It has been superseded by v1.01 which has finer detail but does not include the blocks covering Kalimantan and Sumatra.

Coverage: The map covers a rectangular (N0 to N8, E99 to E121) including the whole of Malaysia, Singapore and Brunei but also including portions of Indonesia, Thailand and the Philippines.

Contours: 10m 100m 500m

Size: 472Mb

Compiling the ASTER GDEM, what I've learnt

Here is what I've learnt during the three steps required to compile the ASTER GDEM into a topographic map viewable on a Garmin GPSr.

ASTER GDEM Malaysia v1.01

Have corrected my recent compilation of the ASTER-GDEM and it is now ready for download. I believe this is the most detailed freely available topographic map of Malaysia available. It is best used combined with other (road) maps as there is not other details apart from the contour lines.

Coverage: The whole of Malaysia, Singapore and Brunei
