基于OpenStreetMap和90 m SRTM的地面站導(dǎo)航電子地圖實(shí)現(xiàn)
[Abstract]:Earth station navigation electronic map is the only platform for operators to monitor unmanned equipment, and it is also an important information source for route planning and autonomous decision-making. The existing navigation electronic maps generally have the disadvantages of high price, insufficient support for elevation data and dependence on the Internet. In this paper, a new implementation method of earth station navigation electronic map based on OpenStreetMap is proposed. Firstly, the original OSM data is used to build the map tile service background, and then the 90m SRTM elevation data is processed into the terrain shadow and terrain color gradient grid file. For each grid file, add the corresponding layer to the style configuration file of the tile service background and define its rendering format; Finally, the map client module is implemented in the earth station software, and the tile is requested from the tile service background and displayed on the interface of the earth station. Using this method, the electronic map of earth station navigation can provide data of 0 ~ 18 zooming levels in China, and display 0-13 zooming levels of stereoscopic landforms without Internet support. This paper uses this method to realize the navigation electronic map module of a ground station of a UAV, and successfully applies the UAV simulation system.
