Getting back out into the Northern Fells again on Saturday, I decided to try and automatically geo-tag my photos using the tracklog from my GPS. There appear to be various solutions for this. Essentially, you need an application to read your GPS's tracklog, which you save in a folder with all the associated photographs. The geo-tagging application compares the date/time stamp of the photo with the tracklog, and writes the co-ordinates into the EXIF data of each photograph. The walk was in the North West corner of the Northern Fells (Wainwright, book 5) and the album is HERE. After a bit of Googling for reviews and ratings of suitable (ie/ free!) solutions, I settled on Geosetter, which is a German product with the option to install in English. For my purposes, very quick and easy to use. I just exported the tracklog as a GPX file, saved it in the images folder, and Geosetter did the rest. The absolute top tip if you intend to do this is to ensure that the time on your GPS and the time on your camera is in sync. Being a technically minded person I obviously did exactly that - after all, I'm not stupid. Unfortunately, I didn't check to see if the date was set correctly... So, my second product endorsement is for another application from the same author, called Exifer. This allows you to batch process EXIF data to correct the time/date stamps. It also does a lot more than that, but all I needed was the date change, and it worked great. The product is discontinued, but as stated, it's quick, simple and did what I needed. However, remember to check the date and time in your camera, and it will be a lot easier!
