Abstract:

Based on the aggregated registered population data of Shijiazhuang as of 24:00 on April 30, 2007, the authors applied the optimized random forest model for population density to obtain the population density grid dataset for Shijiazhuang (SJZ_POP_2007). The SJZ_POP_2007 dataset includes the following data from 8 groups: (1) predicted population density data for Shijiazhuang (Predict_Data); (2) population density data for Shijiazhuang (Result_Data). Validity testing was conducted at the township level, and the goodness of fit (R2) of the result data reached 0.967. The SJZ_POP_2007 dataset has a spatial resolution of 100 m. The dataset is archived in .tif format, and consists of 64 data files with data size of 279 MB (compressed into one file, 132 MB). The related paper was published in Acta Geographica Sinica, Vol. 78, No. 5, 2023.
