| Abstract: | This article focuses on the revision of specification for cartographic symbols of Guangzhou urban basic topographic maps.The project is carried out based on the old specification which was established in 1996 by Guangzhou Urban Planning Bureau,according to the national specification for cartographic symbols of 1∶500 1∶1000 1∶2000 topographic maps（GB/T20257.1-2007）as well as the info-surveying needs.This paper will expatiat on the background,principles,techniques and implementation of the revision project,which can provide some useful experience for similar study. |
