A fast and reliable decision is based on the availability of a precise data basis and expert knowledge. In order to address these aspects for resource planning, we provide an intuitive situation analysis in mixed reality with a seamless transition between conventional location planning and virtual inspection of the operational environment, which in addition to a better understanding of the terrain allows for location-independent cooperation of several users. The basic idea of the presented concept comprises the intuitive application preparation in mixed reality in a realistic 3D environment combined with an efficient 2D situation overview using e.g. a large display, tablet or smartphone. The aim is to enable transparent collaboration between different system environments regardless of the location of the respective users. The aim of the idea is an improved understanding of the terrain and increased situational awareness for fast and demand-oriented location planning. The solution is based on the three building blocks. First, a user-oriented display of high-resolution 3D geodata for a better understanding of the terrain on the basis of data standards, including necessary performance optimizations for use in mixed reality environments. Second, the combination of two-dimensional and three-dimensional display of operational pictures, which allows a choice of means through the synchronization of the information between the different platforms and thus a demand-oriented deployment planning. And third, the support of content-related cooperation of remote users for fast decision making via wired or mobile networks.
