摘要
1:5万数字地质填图,按照规范要求需要1:2.5万地形图作底图。因此,工作中需要制作1:2.5万标准图幅框与地形图匹配作为野外填图手图。本文就1:2.5万标准图幅制作、不同比例尺之间的投影转换及地形图比例参数设置等问题进行详细说明。
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.
