Yesterdays Documentation
Yesterdays is a platform for cataloguing and georeferencing historical images. It was initially developed by MapRVA for use in Richmond, Virginia. Yesterdays is now an OpenStreetMap US Charter Project.
This site documents how images are organized, georeferenced, and searched on Yesterdays. There is additional information available for developers interested in accessing our API or contributing to Yesterdays.
