Research and implementation of terrain model numerical control engraving technology

ZHOU Guokui;Map Institute of Guangxi Zhuang Autonomous Region;  
Conventional processing technology for the terrain model cannot avoid topography expression distortion and inefficient processing.Aiming at this problem,we put forward a numerical control engraving technology based on digital elevation model.The problem of geomorphic feature distortion and micro landform loss is solved by characterizing processing the relief maps,thus the regional geomorphic features are well expressed.Optimizing the matching of the carving parameters according to the geomorphic feature can solve the contradiction between the fine carving and the processing efficiency of a terrain model.The accurate expression and rapid processing of terrain model are realized.Results of production experiments show that,this technology can solves the problem of the representation of geomorphic features,enhance the expression of the terrain model,as well as engrave the terrain model rapidly,which brings about a certain reference for the development and application of the terrain model.
