| 摘 要： | 随着GIS技术的发展，用基于COM标准的ArcObject（AO）进行GIS开发成为一种有效的途径。对AO编程、开发GIS，一个重要的关键点在于开发者具有读懂AO Object Model Diagrams（OMD）的能力。本文从如下3个角度：牢记OMD图例、标记，深刻领会OMD内蕴的地学之道和熟记OMD层次结构，来帮助GIS开发人员阅读、理解AO OMD。同时对OMD中蕴藏的GIS基本线进行了图解。

| Abstract: | With the development of GIS, production of GIS products with ArcObjects(AO) based on COM has become a high-powered method. One of the keys to coding with AO is the capability of understanding AO OMD (Object Model Diagram). This paper introduces one guide to developers. The guide helps the developers understand AO OMD from the following three points: concentrating on the symbols of OMD, focusing on the theory of Geography contained in the OMD deeply, and keeping in mind the inheritance of OMD. In the same time the foundation clue of GIS contained in OMD is clearly diagrammatized. |
