摘　　要：本文分析了栅格数据地形分析具备的优势,设计了基于栅格数据的地形分析原型系统。通过对矢量地图数据处理,预先构建栅格中间层数据,并发布为瓦片数据服务;根据分析的需要对各要素层栅格数据赋予不同的权值,综合后给出面向特定应用的分析结果。通过在原型系统中加载试验数据,测试了系统主要功能,验证了系统设计方案的可行性。Considering the advantages of raster terrain analysis,a terrain analysis prototype system based on raster data is designed.The raster intermediate layer is constructed in advance by processing the vector map data,and published as the tile data service.Diflerent weights are given to the raster data of each element layer according to analysis requirement,and the analysis results oriented to specific applications are presented.Test data are loaded to test the main functions in the prototype system,and the feasibility of the system design scheme is verified.
