SepiaTown is a cultural history project that aims to provide a window to the past by merging photography, geography, and technology, by acting as a forum for institutions and individuals to share and map historical images.
Once they have signed up, users may upload historic images to the site individually or in batches. Each image is given a title, description and keywords, as well as a spatial location represented by a marker on a map.


Mapstraction is a Javascript library. It provides developers with a single interface for a wide variety of Javascript map APIs including Leaflet, Google, Bing, OpenLayers and ESRI's ArcGIS.
A key benefit is that once a developer has loaded Mapstraction, s/he can to switch from one map API to another quickly and easily - often only needing to change a few lines of code.
Mapstraction displays points, lines, polygons and markers on the maps, and also allows developers to add base maps and overlays.
