Refined spatial distribution data set of GDP in hanbantota port area (2015)
The refined spatial distribution data set of GDP in Hambantota port area is obtained by downscaling the GDP data of Sri Lanka in 2015 with 100m spatial resolution based on the land use data and POI data obtained from high-resolution remote sensing images. The land use data are obtained by interactive correction after classification of high-resolution (0.5m) satellite images of Digital Globe and the POI data is obtained through the Internet map. The functional areas are determined based on the POI data, and the weight is determined by the statistics of 100-meter scale GDP of different functional areas. Finally, under the control of regional GDP, the GDP of different functional areas is allocated according to the weight proportion, and the fine scale GDP distribution data with 30 meters spatial resolution is obtained.
