Title: | Automatic Label Generation for Airport Charts | ||||||
Language: | English | ||||||
Abstract: | The integration of electronic airport moving map displays into modern cockpits is a valuable contribution to the situational and positional awareness of pilots during taxi maneuvers. Labels are a key for the perception of the presented map. Comparing labeled map elements with airport signage enables the crew to constantly cross check their position. This reduces the risk of inadvertently entering a wrong taxiway or runway and the risk of related mishaps. The goal of this work is the development of an automatic map labeling system for airport moving maps. The development of the system is based on a thorough analysis of structure and contents of the most comprehensive aerodrome mapping database world-wide. The design focuses on a high quality and good legibility of the computed labeling solutions. Key aspects are the display of the right information at the right point in time, an unambiguous association of labels to their related map elements, and fully deconflicted labels. The completeness and correctness of data must be guaranteed in all processing steps in order to fulfill the strict requirements for aviation use. The target format as well as required source data and display parameters are defined by analyses of existing paper charts. An expert system is used to accomplish the necessary data conversion. A hierarchical data structure is generated with levels-of-detail fitting to different map scales. Position candidates for different label types are defined based on the hierarchical data structures. The final label placement utilizes existing algorithms. The results of the presented system are demonstrated in two applications. On the one hand, labeling solutions for a real-time display of dynamic, electronic airport moving maps are generated. On the other side, labeling solutions for high-precision, printed paper charts are computed. |
