SnapMap allows the user to create a map of any public Instagram account’s 20 most recent geo-tagged photographs. The map walks the viewer through the photographs from the oldest to the newest. Below each photo is the caption, any hashtags, how many likes the photograph received and how long ago the photograph was posted. It is not possible to change the order of the pictures on SnapMap. The geo-tag of an Instagram photo is set during the photograph upload process and cannot be changed once the photograph is posted. It is possible to zoom in on the map by double clicking, but it is not possible to zoom out.The viewer can examine photos out of order by clicking on the individual photograph, instead of the arrows on the side of the page. SnapMap can be used to document an Instagram user’s photographs of a human rights event with a geographic component, such as a march or protest.
SnapMaps can be created by those without prior mapping experience. SnapMap is free for anyone to use and can be viewed on desktop computers as well as mobile devices. The map can be embedded in a website or a link to the map can be provided. SnapMaps continuously change as new geo-tagged photographs are added to Instagram. To preserve a SnapMap of specific photographs the Snapmap can be exported to StoryMap JS. Exporting the map to StoryMap JS also allows the user to change the type of map displayed, edit the text below the photographs, reorder photographs, change the photograph location, and delete photographs.
