A boundary-labeling algorithm of polygon rasterizing for population gridding

Population data is a kind of important national data.Data mining,expression and spatialization of population data are important parts of the population information processing.Though there have been some related studies on the spatial model of population data,the processing and data results are often less efficient or inaccuracy.This paper focuses on the features of polygon rasterization in the population spatialization process,and put forwards an improved boundary-labeling algorithm which can generate population data grid.This algorithm has also been applied and tested,and get better results.
