摘要: 本文探讨了影象地图编制中的影象概括问题,分为比例影象概括、目的影象概括和视觉影象概括。并在实践基础上阐述了影象地图编制工艺。

Abstract: The image map is a product of cartography combining with remote sensing technology.Compiling line maps exists the problem of mapping integration,so does compiling image maps.It is called image generalization.According to the size,important degree,colour characteristics and the result of sense transference,image generalization can be divided into scale image generalization,objective image generalization and vision imago generalization. The scale image generalization means reflecting the regular type features and typical characteristics of mapping objects by means of contracting or enlarging image scales.The objective image generalization means stressing special information,on the understanding of importance of mapping objects by cartographers,by selecting various bands and their combination forms.The vision image generalization means stressing outline,structure and features of major objects after natural eliminating those fragmental features which should be filtered to map scales.
