While idly looking through a CTC magazine I came across a screenshot of a mapping program showing a section of an Ordnance Survey map with a GPS track overlaid on it. This got me thinking that this would be an extremely useful thing to do; at the moment I haven’t any way of using the GPS with a proper map.
I found a thread GPS for unicycling? which mentions the Anquet and TrackLogs programs, but OziExplorer I discovered from the uk.rec.walking newsgroup.
TrackLogs appears to have better GPS integration than Anquet, being built in from the start rather than tacked on to an existing program; however the map area that comes with TrackLogs seems rather small. In my case the Anquet program would come with a map of the entire south west, whereas TrackLogs would come with a smaller area of Somerset, Dorset and a small bit of North Devon, so would be much less useful.
These two both come with smaller scale maps of the entire UK; Anquet at 1:250,000 and TrackLogs at 1:1,000,000. This could be very useful for longer car journeys.
OziExplorer I found later, which does not come with any map data but allows you to use images of maps, such as scanned maps, and calibrate them so routes can be overlaid upon it. This strikes me as being much cheaper in the long run; I already have OS maps for the areas I’m interested in, it seems silly to effectively buy them again on CD rather than dead trees.
Because of this, however, OziExplorer does not do anything with altitude. While this would be okay for car journeys, I find the altitude is a very interesting part of the results from a muni ride.
Currently I’m leaning towards OziExplorer, mainly because of being able to use your own maps, and sticking to my own program to sate my urges for funky 3D visualisations of where I’ve been.
Does anyone use, or have any experience with, any of these? Any opinions would be appreciated!
