全国土地利用格网数据生产技术方法探讨

National Grating Data Production Methods of Land Use

本文在全国多尺度土地利用格网数据需求分析的基础上,基于土地利用矢量网格化生产工程实践,分析和阐述了国家土地利用格网参数选择依据、格网内地类面积的算法、格网综合和批量化处理等主要技术方法。研究结果表明:利用本研究开发的土地利用矢量网格化软件,对县级土地利用矢量数据进行网格化处理,可快速生产合格的全国土地利用地理格网数据,并将极大的促进全国土地调查数据成果的社会化共享应用。

According to the national multi-scale analysis of land use data grid needs and the practice of engineering producing in grid vector of land use,this paper has analyzed and expounded the grating parameters selected on the basis at national land use,algorithms within the land area of the grid,grating integration and batch processing,etc...The results show that the land use vector grating software developed by our research to make on county the land use vector data for grating processing could quickly produce the qualified national land use geographic grid data,greatly facilitate the achievement of socialization in sharing data about the national land survey.
