Bunker Pictures - GPS (Global Positioning System)

Bunker Pictures has started to collect GPS information about bunkers since May 2008.

We will provided GPS coordinates according to the DD°MM.mmm' (N52 00.591 E4 43.845) standard.
Locations which we have visited in the past are not available in GPS, but if we can collect data from Google Earth (GE) or by other sources we will try to add those to the older datasheets.

We try to give the correct data but if there is a mistake, please contact us by sending an email.
