【Abstract】 Based on the geographical Digital Line Graph(DLG) provided by National Mapping Bureau, and the data format transformed by map projection which is needed by China new weather radar (CINRAD), we studied the technique of weather radar geographical information and designed a corresponding system software. This system can create maps according to the CINRAD format of China within the radar detectable boundary in real time,and also perform the overlapping of maps and radar products on radar display terminals.更多还原
