摘要: 卫星遥感集邮品数据集 (1957-1959) 汇集了23个国家在1957-1959年间 (国际地球物理年) 发行的349件集邮品。该数据集是在林超地理博物馆实物馆藏品的基础上,经数字化整理和归档后完成。该数据集中汇集的集邮品包括太空时代开始时期各国为纪念苏联成功发射2个卫星系列 (地球观测系列和月球观测系列) 和美国成功发射5个地球观测卫星系列共计7个卫星系列、29颗卫星纪念邮品。该数据集的全部实物藏品归档在林超地理博物馆,全部信息在林超地理博物馆 (网络版) 公益性共享。

Abstract: Census data with the spatial scale of administrative district cannot reveal the spatial differences sufficiently. Meanwhile, this kind of statistical population data cannot be integrated and analyzed with most of other gridded geographic datasets. People in pixels provide an effective way to solve this problem. We established multivariate statistical models for population in 1 KM pixels based on the correlation relationships between population and land use types. The urban population density, traffic conditions, DEM and total amount control were used for model correction. Forty counties with township population data from east, west and middle of China were chose for precision verification. The errors of the spatial population data in these counties are between 4.5% and 13.6% and most of them are less than 10%.

Key words: China, GDP, grid, spatial data, 2005, 2010.
