中尼交通廊道1：50万地质图数据集（1999）

该数据为中尼交通廊道（国内段）1：50W地层数据，地层图可以表达区域构造特征的成果，又是研究区域构造的重要方法，对中尼交通廊道（国内段）区域构造研究的不断发展有着重要的作用。此数据可以用来研究地质灾害与地层岩性之间的空间关系，是揭示中尼交通廊道沿线的地层岩性特征的基本数据。数据由1:50w地质图，经扫描配准，并矢量数字化，数字化时精度保证在2个象元以内。数据可用ArcGIS、ENVI或其他地理信息系统和遥感软件打开使用。平面坐标系为：WGS1984。

This dataset is the 1:500,000 stratigraphic data of the China-Nepal Transportation Corridor (domestic section). The stratigraphic map not only visually represents regional tectonic characteristics but also serves as a critical approach for regional tectonic research, playing a pivotal role in the ongoing advancement of regional tectonic studies on the China-Nepal Transportation Corridor (domestic section). This dataset can be employed to analyze the spatial correlation between geological hazards and stratigraphic lithology, and constitutes the fundamental data for uncovering the stratigraphic and lithological features along the China-Nepal Transportation Corridor. The data is derived from the 1:500,000 geological map, which was scanned, registered, and subsequently vectorized, with the digitization accuracy guaranteed to be within 2 pixels. This dataset can be opened and operated using ArcGIS, ENVI, or other geographic information system (GIS) and remote sensing software. The horizontal coordinate system adopted is WGS 1984.
