I purchased a GPS datalogger this past summer to use while on our Great Britain trip. I carried the datalogger with me and it logged our GPS position every 5 seconds to create a path of where we had been. This path could then be used for geotagging photos and viewing maps of our trip, like this one below: Click to view map in new window.
I bought the Gisteq BT100 logger. It's about the size of a pager, so it's fairly unobtrusive in a pocket, and its software can geotag RAW files which is a must for me. It's sensitivity can be a little low when in high buildings or trees, but from what I've read it works better for low speeds (i.e. walking rather than driving) than the higher-sensitivity GPS units). |
