Armed with a new (budget) GPS of my own (Garmin Etrex 20), I’ve combined a holiday on the Island of Colonsay with lots of recording of tracks and the like. I’m now engaged in slowly making use of this data.

Colonsay isn’t well mapped, partly because what’s of significance there is more the natural environment and individual buildings than the few roads and tracks. This means that small edits have a very positive effect on improving the map.

Interested to find out that my GPS tracks are consistent (on different days) in indicating a small offset on the Bing Imagery, so I’m now correcting for this.

As this is a small area with few contributors I’d be happy to hear from others who have worked on the area. I’d also like help if anyone has the time to map the buildings which can easily be seen on the Bing imagery (although please also correct for the imagery offset - Scalasaig harbour area should provide a reference for this).
