=== Recorded GPS data ===

There are several ways to take GPS tracks with phones or handheld GPS units (coming soon). Even if your device cannot take tracks, using geotagged photos or an app to get GPS coordinates will work for many things. GPS tracks are good for recording new paths, roads etc. Simply start taking data, walk, drive or bike the new path, road etc, and record the name of the track and maybe a rough sketch of where it is on your walking papers. You can also take one track of your entire trip, and annotate the beginning and of the new area. If you see an interesting object, you can either take a geotagged photo of it, or use a handheld GPS unit to get the coordinates and write it down on your walking papers, with notes about what it is.
