摘要
According to the mapping requirements,1:50000 digital geological mapping need make the 1:25000 standard topographic maps as the base map.Therefore,we must make 1:25000 standard sheet frame and topographic map match with field mapping hand chart.The authors have participated in the project area adjustment,and summarized some process data preparation and operation skills.This article introduces such problems as production of 1:25000 standard map,projection transformation between different scales,and scale parameter definition.
