基于ARCGIS土地利用现状图符号化的探讨

Research of the Symbolization in Land Use Maps Based on ArcGis

地图符号是地图表达空间信息的语言单位,地形图数据的符号化直接关系到地形图的可视化表达和使用,通过对地图符号的解读,可以直观地了解地图所表达的地理信息。提出基于ArcGIS的1∶10 000土地利用现状图的符号化的繁琐性,采用ArcGIS Engine二次开发对其大量数据进行自动符号化处理。

Map symbols represent the basic unit of the spatial information on the map.Symbolizing the topographic map data directly relats to the visual expression of the topographic map.Interpreting the map symbols can intuitively show the geographic information.In this paper,based on ArcGIS 1：10 000 land use map,taking account of the complication of the symbols,massive data automatically processing was achieved by the second development of ArcGIS Engine.
