I've been at this for about three months now and think that I finally have the hang of the basics. I'm using an eTrex Vista HCx GPSr and an old Canon PowerShot A510 digital camera. Most of the time I map via mountain bike; a Trek 4300. I use GPSPhotoLinker (Mac) to geotag the photos and JOSM to do most of the editing. For some reason, the Yahoo Sat WMS is no longer working in JOSM, so I use merkaartor if I need a satellite image or if I need to draw a large number of ways.

There are a very small number of us mapping in Northeast Thailand so the going is slow. Some cities with active mappers (such as Khon Kaen) are steadily improving while others are rather static. For example, it appears that no one is mapping the tourist-frequented Nong Khai (gateway to Laos).

At the moment I'm concentrating on getting the roads in my immediate vicinity mapped and named. Once that's done I'll work on getting more POI's identified and mapped.

One of the slowest parts of the process is getting Thai names entered in Thai script. I am not fluent in Thai, although I can read. I've never mastered the Thai keyboard, so there is a lot of hunt and peck. And, sometimes the signs that I photograph are in a fancy font that I have difficulty with.

As I've mentioned, http://keepright.ipax.at/ has been a very helpful learning tool.
