基于夜间灯光数据的珠三角地区镇级GDP估算
Township GDP Estimationof thePearl River DeltaBased on the NPP-VIIRS Night-Time Satellite Data
摘要
Abstract
Though the high resolution data of GDP distribution is difficult to collect, it is very important for small scale regional development research. Night-time satellite images can be used to estimate GDP of administrative unit. In this paper, DMAP-OLS and NPP-VIIRS are used to estimate township GDP ofthe Pearl RiverDelta district: DMAP-OLS data are employed to modify NPP-VIIRS data, and then regression model about GDP and NPP-VIIRS Pixel brightness are built to estimate township GDP. Regional difference coefficients are employed to adjust the township GDP based on city level GDP data. Experiments show that the estimating accuracy of township GDP value in 2013a reaches to 85%, and NPP-VIIRS data is valid data resource for township GDP estimation.关键词
