数字时代的地图泛化与GIS升维
Extending Maps and Expanding GIS in the Digital Era
摘要
Abstract
Classical cartography is established upon the three theoretical pillars of map projection,map generalization,and map symbology.However,its two-dimensional,static representations are becoming increasingly inadequate when confronted with the diversified application scenarios of the digital era.Information and communication technology is continuously reshaping the technical paradigms and application boundaries of cartography.Advancements in observation techniques,the enhancement of representational capabilities,and the expansion of appli-cation demands have gradually led maps to exhibit a generalized character.While geographic information systems(GIS)originated from cartography,this character has,in turn,provided a new impetus for the development of GIS data organization,spatial analysis,and visualization.This paper analyzed the drivers of extending maps and the pathways for expanding GIS,and explored the underlying logic by which the former facilitated the latter.Finally,taking the smart city development of Shenzhen City,Guangdong Province as a case study,the paper demonstrated the evolution of both concepts'connotations and denotations within the digital era.关键词
