Why was the data set created?

The purpose of this dataset is to give geologists and other scientists a spatial database of major coal mines and their production 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?

   Coalfield Prediction Map of China (source 1 of 1)

   Publishing House of Surveying a, General Bureau of Ministry of Geology a, 1996, Coalfield Prediction Map of China.

   Type_of_Source_Media: paper map

   Source_Scale_Denominator: 2500000

   Source_Contribution:

   This map provided locations of mines and annual coal mine production in metric tons in China

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

   Date: 12-May-1999 (process 1 of 1)

   The coal mine locations and production values were digitized off of the Coalfield Prediction Map of China.

   Data sources used in this process:

   • Coalfield Prediction Map of China

3. What similar or related data should the user be aware of?

   Publishing House of Surveying a, General Bureau of Ministry of Geology a, 1996, Coalfield Prediction Map of China.

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

   All coal mine production is labeled correctly

2. How accurate are the geographic locations?

3. How accurate are the heights or depths?

4. Where are the gaps in the data? What is missing?

   This data set is a complete coverage of all coal mine production in China.

5. How consistent are the relationships among the observations, including topology?

   No tests for accuracy were done.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
