摘要
为给西藏地区1∶5万地质调查提供地理底图,在MapGis平台下开展连编带绘编制地质图地理底图,并以工作区遥感影像等资料作为底图进行修编及补充成图工艺方法与质量评价。
In order to provide geographical base map for 1 ： 50 000 Geological Survey in Tibet, considering the factual circumstance of lacking large - scale topographic map in Demingding district in Tibet, the author discusses a new map- ping technlogical method that magnifies 1 ： 100 000 scale topographic map to 1 ： 50 000 scale. Geological maps and geographic base maps are compiled and drawn in MapGis platform. The author collects the remote sensing images and other data of the work area for the base map, makes the revision and supplement map of technology and evaluation.
