影像地形图产品模式设计与关键技术

Product pattern design and key technology of image topographic map

以广东省1∶10000影像地形图为例,在需求调研分析和生产试验的基础上,设计了影像地形图产品模式,探讨了等高线生成、高程点提取、矢量要素选取、注记及其符号化、图廓整饰等关键技术,研制了相应的生产工艺和技术方法,并制作了产品样本。该研究成果已形成系列技术文档,可为影像地形图的设计和规模化生产提供参考。

Using the case for 1∶10000 image topographic map in Guangdong Province,on the basis of investigation,analysis and production test,this paper designs one product pattern of image topographic map,discusses the key technologies such as contours generation,elevation point extraction,vector element selection,annotation,symbolization,and map border decoration.The corresponding production process and technical method are developed,and the product samples are made.These research results have formed a series of technical documents,which can provide reference for the design and scale production of image topographic map.
