THREE DIMENTION DIGITAL MAP SYSTEM

摘要

PURPOSE: A 3D digital map system is provided to implement navigation using 3D geographic information and ground anti-collision method. CONSTITUTION: A geographic information application module(110) corrects accurate navigation calculation by respectively receiving data from an EGI(Embedded GPS/INS)(111), a radio-altimeter(RALT)(112) and a map database(113). The geographic information application module transmits the corrected data to an anti-collision module(120), a topography following module(130) and a ground target distance and location measuring module(140). The anti-collision module generates warnings about colliding with ground or obstacles. The topography following module generates a course following topography. The ground target distance and location measuring module calculates distance and location information of a target.
