Why was the data set created?

The purpose of this dataset is to give geologists and other scientists a spatial database of coal fields in China. This data set will be utilized in energy research and cartographic projects.

How was the data set created?

1. From what previous works were the data drawn?

   Chinese Academy of Geological Sciences, 1992 (source 1 of 1)

   Geological Publishing House, Chinese Institute of Geology and Mineral Resources Information and Institute of Mineral Deposits of Chinese Academy of Geological Sciences, 1992, Energy Mineral Resources Map of China and Adjacent Seas.

   Type_of_Source_Media: paper map
   Source_Scale_Denominator: 5000000
   Source_Contribution: This map provided all coal field locations
   

2. How were the data generated, processed, and modified?

   Date: 02-Mar-1999 (process 1 of 2)

   The coal fields were digitized off of the Energy Mineral Resources Map of China and Adjacent Seas map. Data sources used in this process:

   • Chinese Academy of Geological Sciences, 1992

   Date: 09-Feb-2000 (process 2 of 2)
