Display and Applied Study of MapObject Based Regular Grid DEM
Author(s): 
Pages: 65-67
Year: Issue:  5
Journal: HYDROGRAPHIC SURVEYING AND CHARTING

Keyword:  规则格网数字高程模型MapObject地形分析;
Abstract: 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.
