Mapper since:
May 20, 2009


I do most of my plotting in Devon, always on foot. Have written several GUIs to make OSM more accessible.

It took me 3 years to come to grips with the non NT IMG fileformat (TRE RGN NOD LBL) and the way highways,pois etc are plotted and networked in the RGN - my findings are published in the IMG Explorer,which you can download from my site. Have explored Garmin’s Junction View format (JCV) and the GPI file structure - more info on website.

Maps fascinate me but regrettably, judging by many satnavs, most if not all maps look pretty dire , bleak and uninviting. Because of this I developed TYPWiz 6 and Map Theme Maker for Cars and Zumos.

If you want to produce your own Garmin maps without much effort , then download mapuploader 6 , a GUI to create gemapsupps & upload osm maps to Basecamp etc. It can also check your style and TYP files & generate contours for most regions of the world. You can download OS50 type maps of Devon & Cornwall based on OSM from my Devon site.

Am keen on creating walking/hiking routes & produced a TYP file and style sheets capable of showing any hiking route with a unique colour. Check out ‘Tricks with mkgmap style sheets’ to see how you can add ‘active routes’ to your maps.

Recently, I have been exploring FIT files and have produced FIT Converter and written FIT for Dummies.
