Global Distribution of Lava Channels on Venus

This dataset is a shapefile containing lava channels mapped globally on the surface of Venus. These channels were mapped in ArcGIS 10.8 and converted to ArcGIS Pro.

Bledsoe_etal_Channels.zip is the shapefile containing the map traces of 66 of the 72 named channels on Venus, following the methods detailed within Bledsoe_Methods.pdf. There are 121 polylines, designated by primary length (1), secondary (2), and data gores (straight). Details are listed within the metadata and attribute table.

本数据集为矢量形状文件（shapefile），收录了全球范围内金星表面已完成测绘的熔岩河道。上述河道通过ArcGIS 10.8完成测绘，并已转换至ArcGIS Pro环境。
Bledsoe_etal_Channels.zip为该形状文件的压缩包，遵循Bledsoe_Methods.pdf中详述的测绘方法，收录了金星72条已命名河道中的66条的测绘迹线。文件内包含121条多段线，按主长度（标记为1）、次长度（标记为2）以及直型数据割线（data gores）分类，详细信息已在元数据与属性表中列明。
