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.

Technical Details

I used dem2topo with these settings:

* SF 10
* Minor 10m
* Intermediate 100m
* Major 500m
* Shoreline 2m

Here's a typical header of the Polish Map prior to compilation with cgpsmapper:

Mapsource-compatible format

http://three15.org/topo/SRTMv4/moe4.zip (216 Mb, EM + WM, SRTM4 + HydroSHEDS)

Instructions:
1. Requires Mapsource (6.13 only) and some amount of computer know-how
2. Download and extract the contents of the file into C:\Garmin\moe4
3. (If you would like to change the above directory, be sure to edit the file moe-srtm4.reg)
4. 'Run' the moe-srtm4.reg file to make the necessary changes to the registry. Warning: this could critically affect the functioning of Windows and or Mapsource. If you are uncomfortable with this step, I would advice you not to install it. I can't provide technical suppport.

The rest of South East Asia (coming later)
