Geographic Coordinate Projection Fine. Navigation Technology Research And Application

With the rapid growth of the national economy, the rapid and efficient transportation becomes the important factors in economic development. GPS and GIS technology as the foundation of all kinds of vehicles scheduling and monitoring systems have been pay extensive attention by more and more engineers,and widely used in various fields. In all kinds of vehicles scheduling and monitoring systems,how to conversion between the position information which is measured by the GPS terminal equipment and the information from the GIS of our country, the fusion of GPS and GIS technology is the key.┄┄This paper is based on the actual demand," The truck automatically scheduling system of The Yimin river open-pit mine " as the main research object. In understanding the GPS principle and the current situation of our country's geographic information system and the feature of geographical information in Yimin River's open-pit mine,innovative and exploratory research the algorithm of coordinate transformation and inverse coordinate transformation between different coordinates system and the algorithm in map projection coordinate.The main results are as follows:1. A detailed study in coordinate transformation algorithm between the WGS-84 coordinate system and BJ-54 coordinate system.┄┄2. A detailed study of the equation and the inverse equation in projection coordinate between BJ-54 coordinate system and BJ-54 plane coordinate system. BJ-54 plane coordinate system and the Yimin River's open-pit mine coordinate conversion relations.┄┄3. Find another handy algorithm in coordinate transformation between region coordinate and the WGS-84 coordinate system.4. Study how to use Artificial Neural Network algorithm to find the best way in road network at mining area vehicles scheduling.┄┄...
