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 -
Hmm, not sure i understand what you've surveyed here. Is it boundaries, hedges, hollow-ways and earthworks?
Wouldn't it save time to just rectify the google map, then trace off that?
How do you 'correct' your blue lines to the orange ones?
