Maps of Malaysia

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.

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.

I've realised that I used a less than ideal setting for the Level0 setting. I should have used 24 but I used 22. I believe this value relates to the number of bits allocated to addressing points on Level 0 - the level in which the detailed 10m contours reside. 24 bits corresponds to a resolution of 2.4m vs 9.6m for 22 bits. Perhaps this explains why there was a considerable loss in the resolution of the contours after converting it with cgpsmapper.

Will re-compile and upload an updated map soon. Am expecting it to be bigger but with more detail preserved.

Am in the final stages of producing a topograpic map of much of South East Asia using the SRTM 4 data. For practical reasons, have reduced the vertical resolution to 50m contour line intervals. Will publish this soon ...
