%X The railway distribution map is the basic data in the mapping process. For the convenience of users, we compiled the railway dataset of the Heihe River Basin based on the railway dataset distributed by the National Basic Geographic Information Center, the "Gansu Provincial Atlas" compiled by the Gansu Provincial Map Geographic Information Center, and the Tian Map and Gu Ge Map published by the China Surveying and Mapping Bureau. This data basically reflects the distribution status of railways in the surrounding areas of the Heihe River Basin around 2010The railway coding adopts the national standard for basic geographic information system data classification and coding - "Classification and Coding of Land Basic Information Data" (GB/T 13923-92), with a five digit code (National Basic Geographic Information Center 2010)
