The main use of PicaGeoTag is to set and manage location data in your photos.
It can also allows you to view your routes or view the location of your geolocalized images (even without GPS path).
The principle is to record your course while taking pictures. Then you could compare the shooting date recorded in the file of the image with the date of the GPS points to determine the precise location of the image.
So you need a device capable of recording your movements while you take your photos. This can be a specialized device like a GPS tracker or a simple smartphone with a GPS application (for example GeoTrack). The only condition is to be able to export the data recorded by the GPS in order to load them in PicaGeoTag.
The program accepts the two main formats, which are the GPX format or the KML/KMZ formats of Google Earth. If you have choice, prefer the GPX format that is more simple to decode.
Your images must also be saved in a format that accepts meta data. Currently, PicaGeoTag knows how to use the main types of files supporting metadata: jpg , jpeg , jpx , j2c , j2k , jif , jpc , png , tif , tiff, cr2, dng, erf, nef, mrw, orf, pef, raw, crw, rw2, nrw, srw .
Viewing photo locations
If your photos have been geolocalized, you can load them in PicaGeoTag to view their position on the map.
This can be useful for finding a place or to group images by areas.
Viewing GPS tracks
You can load your GPS tracks to visualize your routes. Simple statistics are displayed as the duration or the length of the route.
