If you like shooting and collecting pictures, you might be interested in geotagging your pictures. More and more software can use such geospatial metadata information for categorizing and visualizing these pictures, for example in an interactive map. Today, on I love Free Software day, I show you a way how to batch geotag your pictures with OpenStreetMap and Free Software only.
Geospatial metadata, together with time-stamps, seem to me to be the most important meta-information a picture can have. It is extremely helpful in organizing pictures, for example to cluster pictures that have been taken at the same location but at different times. Personally, I always need this data whenever I upload my pictures to Wikimedia Commons, as it asks me during the process about the geolocation of these pictures. Before, each time I had to look up the data individually on OpenStreetMap and fill in the information manually. Pretty fast, I got bored of this and I was looking for a way to write this information automatically into my pictures even before uploading.
One solution to this is a GPS-recorder built-in or attached to the camera. Unfortunately, very few cameras come with a GPS-recorder built-in and additional GPS-modules are a way too expensive for most hobby enthusiasts. Fortunately, there are software-solutions, that enable you to use just any other device which is able to capture GPS-tracks and then later merge this recorded geo-information with your pictures taken.
For sure, there are multiple ways to do this. In this blogpost, I will show you how you can do this with a smarthphone, OpenStreetMap and Free Software. All you need is:
- a smartphone running Android or a custom fork
- a camera
- GPS correlate
