A spatiotemporal dataset for knowledge discovery on
population, environment and development in China
Alt title:
1. Abstract
Descriptions of the spatial and temporal variations in population and their
interactions with the environment and development are highly required to better
respond to the population problems associated with social, political and
environmental issues. Here, we present a dataset for knowledge discovery on
correlations between population, environment and development in China. The dataset
comprises items of population, basic geography, climate, topography, landform,
land use and land cover, vegetation, natural resources, infrastructure, economy,
nighttime light. The data is expressed as raster or vector format covering a
remarkably long period from 1980 to 2010. The dataset is collected from multiple
international and national data-sharing canters, official statistics, etc. All of
the data items are quality controlled and unified into an identical dataset with
the same spatial scope, resolution and period using GIS techniques. The database
is expected to be useful in demographic and environmental studies such as
extracting the knowledge of the relationship between population and naturalsocial-economic conditions, simulating how population influences the environment
and society, etc.

NDVI data, the normal value is from 0 to 1 and water pixels have a value of -10.
(8) Natural Resources: This dataset includes water resources, land resources and
forest resources. The data is expressed as raster format with 1km resolution and
projection of albers. Attribute information mainly includes amount of water
resources distribution, quality of the cultivated land, and NPP distribution. The
amount of water resources is acquired from the Data Sharing Infrastructure of
Earth System Science. The quality of the cultivated land in China is obtained from
the Data Sharing Infrastructure of Earth System Science. The original NPP data are
acquired from the LAADS Web of the Goddard Space Flight Center, NASA
(http://ladsweb.nascom.nasa.gov/index.html). The original data are integrated both
on spatial and time scale, and then transformed to the same projection with other
data.
(9) Infrastructure: This dataset contains two data items including the distance to
the railway and the distance to the river. The two data items are both expressed
as raster format with 1km resolution and a projection of Albers. The two item
cannot bedirectly achieved from existing observed data. To calculate the indicator
of distance to railway and distance to river, we firstly convert a raster dataset
with a spatial resolution of 1 km into a point feature. Then we overlay the
feature with the feature of river or railway, and calculate the nearest distance
for each point. The ‘Near’ analysis in the proximity analysis tools provided by
ArcGIS 10.1 is used to calculate the two indicators.
(10) Economy: This dataset contains 5 years (1995, 2000, 2003, 2005, 2010) Gross
Domestic Product (GDP) distributions cover the whole land region in China. The
data is expressed as raster format with 1 km resolution and a projection of
Albers. Attribute information mainly includes gross annual GDP value (unit: ten
million yuan per square kilometer). The source data are originally provided by
Data Sharing Infrastructure of Earth System Science (http://www.geodata.cn).
(11) Nighttime Light: This dataset contains 18 years China’s night time light
with 10 km resolution and a projection of Albers. The attribute information is
digital number with a range of 0 to 63. The source data is obtained from NOAA
national geophysical data center Earth Observation Group
(http://www.ngdc.noaa.gov/eog/). We extracted the nighttime light of China from
the original global scale data.
