摘    要:主要研究了基于MapObject的规则格网DEM的显示以及其应用。提出了一种将国家标准交换格式的DEM模型数据转换为Shape格式的空间数据的方法,并且用VB.NET语言结合MapObject可视化组件实现了对佛山地形的数字地形分析。该方法不需要大型的专业地理信息软件作支持,直接从底层开发,灵活性高,成本低,比较适合面向特定用户小型地理信息系统,为地理信息系统软件开发人员提供一种新思路。

关 键 词:规则格网  数字高程模型  MapObject  地形分析

Abstract:This paper mainly studies display and the application of MapObject based regular grid DEM.The paper also presents a method that can convert the DEM data of the national standard exchanges format to the data of shape format.Moreover,the paper carries out the digital geography analysis of Foshan city through the language of vb.net and the visualization component of MapObject.The method needn't to be supported by big special geographic information software and can be developed directly.The feasibility is high and the cost is low,so it suits to develop the small scaled geographic information system for certain customer and provides a kind of new way to the developing personnel of geographic information system.
Keywords:regular grid  DEM  MapObject  topography analysis
