Google-Earth

A geographical Information System based on Google Earth that let the user explore Sven Hedin’s historic expeditions.

 

Finding historical camera locations can be an extremely time consuming task. Therefore we use a powerful methodology based on geographic information systems (GIS). By georeferencing Hedin’s historical maps and importing them into a GIS, we get a framework for our journey. The next step is to use virtual repeat photography for locating Hedin’s camera stations. It is a method where you look for terrain features in a photograph and try to identify those same features in the 3D-space of the GIS, before searching for the physical location. Using this method we can narrow down the search area for a specific camera location to a radius of tens or hundreds of meters instead of kilometers. This reduces the time required to find it from days to hours.
