HAve been working all day on the Croatia Project GIS... and thought this may interst you.. showing you how you can use a Garmin handheld and get good results... as long as you know where you are (thanks Googlemaps! )
I rectify the googlemaps using OziExplorer and QGIS. then plot my Gps tracks.. (blue lines) which represent the walls I walk. I am then able to 'correct' it to the real location (the orange lines) job done... the acuracy is out by quite a bit, but not so bad I can't recognise where I am... so am now a happy puppy! I save each track (site number) and then clear the tracks and record the next track/wall/ it seems to work well.
have a look - and yes I am still working on teh QGIS for archaeologists... there are others who are far more advanced than me,..... and a local group called CRISP... I will be talking with them about a toolkit. (opensource) along with my own partnership Digital Past (we do things like Open Archive and the Bute website)
