川藏交通廊道地质图（2002-2007）

数据源于全国1∶100w数字地质图空间数据库矢量化而成。根据川藏交通廊道区域范围及1：100w地形图图幅划分方式，使用了H45、H46、H47、H48、I45、I46、I47、I48八幅标准图幅的地质图，数据源格式为wp区文件，利用相关软件转化为shp格式的矢量文件，可用ARCIGS软件查看、编辑。本数据含有含地层、地层符号、岩石类型等基础地质信息。地质数据的获取，能够基本了解到川藏交通廊道范围内的地层、岩性情况，有利于追溯泥石流、滑坡灾害发生的地质条件。This dataset is vectorized from the national 1:1,000,000 digital geological map spatial database. Based on the regional scope of the Sichuan-Tibet Transportation Corridor and the 1:1,000,000 topographic map sheet division rules, geological maps of eight standard sheets including H45, H46, H47, H48, I45, I46, I47, and I48 were utilized. The original data source was in WP zone file format, which was converted into shapefile (.shp) vector files using specialized software, and the converted files can be viewed and edited with ArcGIS software. This dataset contains basic geological information such as strata, stratigraphic symbols and rock types. Obtaining this geological data allows for a basic understanding of the strata and lithology within the Sichuan-Tibet Transportation Corridor, and facilitates tracing the geological conditions for the occurrence of debris flow and landslide disasters.
