Neatline
Neatline is a suite of plug ins that allow you to create "geotemporal" exhibits that plot onto maps or photographs. It is a fantastic resource for those wanting to create visual stories that specifically engage with elements of location or time. With Neatline, you can place items onto modern or historical maps, create timelines, or examine visual elements of a photograph.
