Historical Street View API
Server for the Historical Street View — located photographs, paintings and views of the past, indexed in space and in time.
Photography only goes back to the late 18th century, but humans have been making located views of the world for far longer. The Historical Street View project collects those views and lets you walk through them on a map, choosing both where and when you stand.
hsv-api is the back-end that serves those located views;
visions.ofthepast.org is the public
front-end built on top of it.
