There are a number of stand-alone Windows apps and web apps that led you geotag photos by matching the time they were taken with points on a GPS track (see the geotagging category of this blog for examples). But all of them require you to start up the program, load in the photos, load in the GPS track, and then start up the geotagging process. Flip Fahrenfort geotags a lot of his photos, and got tired of the multiple steps involved. So he wrote GeoHarvest, a program that automates the process to a large degree for owners of Oregon Garmin GPS units. When a memory card or camera is attached to your computer, it can automatically download a copy of digital photos from a memory card/camera to a folder of your choice, and keeps track of the photo filenames. When you connect a GPS, it will download track data and save it in GPX format. It then matches up the track times with the times the photos were taken, and geotags the photos with the appropriate coordinates.
The program can run continuously on your system, monitoring for all inserted memory cards or attached cameras with images to download, or GPS units with tracks to download as well. But if you want it to run this way, you’ll have to copy a shortcut to the program to your Startup folder manually, since the program doesn’t come with an install program that does that. It also can run in single-transfer mode, so that you can connect the data sources, have the photos geotagged automatically, then have the program terminate.
Unfortunately, since I don’t own a Garmin Oregon unit, I was unable to figure out how well it works with that unit. And while the program option suggest that you should be able to get the program to work with other GPS models with some manual work, I was repeatedly unsuccessful at this – GeoHarvest refused to accept GPX files generated by multiple programs. There are online help pages on program configuration and usage; if you can get it to work with your non-Oregon GPS, please leave a comment below.
