I store a photo of each trailhead as an attribute of the feature in a field named ‘Photo’, see below.

For example, I maintain a GIS point dataset for Sedona hiking trails called ‘Trailheads’. Here, the photo itself is not georeferenced but is instead tied to a GIS point, line, or polygon. The second way to store digital photos in your GIS is to include them as attributes of your GIS features.

A GPS unit with a stand-alone camera and office software for photo-linking.

The goal of each is the same – assign geographic coordinates to the EXIF header of your photos – a process called geotagging. The workflow you use depends on the hardware and software you want to use. There are a number of ways to use GPS to georeference digital photos. It is also a good way to create a geoscrapbook to document a journey as I’ve done for one of my Sedona hikes, below.

This method is useful for showing landscape features, perhaps to show how features and terrain change over time. Because it is georeferenced, the photo is mapped in projected coordinate space so you can see it on your map in its proper location. One is to have a georeferenced photo that is added as its own layer in ArcMap. Great! Now you need to determine how you’d like the photos to behave. You’ve decided that you want to add digital photos to your GIS. The information for these articles is taken from my Adding Digital Photos to Your GIS e-course. In this multiple-part blog, I will attempt to shed light on this topic so you can find the equipment and workflow that’s right for you. Finding that workflow, however, can be extremely frustrating due to the myriad of GPS and camera hardware and software options. While there are many ways to add digital photos to your GIS, I find that using GPS is the easiest – provided you have a useful workflow.
