I'm a keen hiker and geocacher, so I tend to record and upload data for footpaths/bridleways and other paths to OpenStreetMap.
I'm also responsible for compiling mapsets in Garmin IMG format for the whole of the UK, with or without contour data.
MapSource/BaceCamp versions are also available for PC for those that have limited memory Garmin GPSrs. I've also created Mac versions for use in RoadTrip/BaseCamp for OSX.
My maps and more details about me can be found here:
