Ambulance planning includes the problems of locating ambulances and bases as well as relocating ambulances throughout the day. Especially for determining (optimal) ambulance locations many different models and approaches exist. Most of them are presented for a special country or region. It would be interesting to study how they perform for other regions, especially for Germany. For doing so, a set of instances is needed that includes different characteristics. We therefore discuss accessible data and present a set of instances derived for Germany.
