Why was the data set created?

To describe areal extents of environmental pollution sources of fluorosis affected areas in China. This dataset will be used to provide support for the assessment and analysis of coal quality and potential inventories and risks to human health in China.

How was the data set created?

1. From what previous works were the data drawn?

   Endemic Fluorosis map of China (source 1 of 1)

   Chinese Academy of Sciences(ed.), and The Central Committee of Chinese Communist Party(ed.), Unknown, The Atlas of Endemic Diseases and Their Environments in the Peolpe's Republic of China: Science Press, People's Republic of China.

   Type_of_Source_Media: paper

   Source_Scale_Denominator: 12000000

   Source_Contribution:

   The paper map provided rates of fluorosis and distribution in China

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

   Date: 1999 (process 1 of 1)

   The regions of endemic fluorosis were digitized from 12000000 map of "Environment Type Map of Endemic Fluorosis Affected Areas of China" in "The Atlas of Endemic Diseases and their Environments in the People's Republic of China."

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

   People's Republic of China, Unknown, The Atlas of Endemic Diseases and Their Environments in the People's Republic of China: Science Press, People's Republic of China.

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

1. How well have the observations been checked?

   Line work was captured by hand digitizing from a 12000000 scale paper map. Arc and polygon attributes are based on the published thematic map.

2. How accurate are the geographic locations?

   The original paper version of high flouride pollution sources in China at a scale of 1:12000000; it is not intended to be used at a more detailed scale.

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 high flouride pollution sources in China. based on information present on the 12000000 thematic map.

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

   The coverage is a net coverage containing arcs and polygons. Each polygon has a class attribute classifying high flouride pollution sources in China.

How can someone get a copy of the data set?

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

Access_Constraints: None

Use_Constraints: None
