3D Georeferencing of Historical Photos by Volunteers [chapter]

Timothée Produit, Jens Ingensand
2018 Lecture Notes in Geoinformation and Cartography  
Historical photographs are a very rich source of information that can be useful in a variety of different contexts such as environmental analyses, land planning and illustration of landscape evolution.  ...  However to reach this goal the images must be accurately georeferenced. In this paper we propose to use the crowd to perform the 3D georeferencing of collections of historical images.  ...  The sum of all information about the volunteers can be used to target specific audiences for instance in a social media campaign.  ...
