基于AE的SimpleGIS框架的搭建

ArcGIS是Esri公司集40余年地理信息系统（GIS）咨询和研发经验，奉献给用户的一套完整的GIS平台产品，具有强大的地图制作、空间数据管理、空间分析、空间信息整合、发布与共享的能力。本人主要就AE搭建框架做简单的介绍

框架是指一个系统的全部或部分可复用设计，通常由一组抽象类和类之间的协助组成，其有几个特点。

1.模块化：应用框架可以从逻辑上划分为若干个不同的功能模块。

2.可重用性：代码的可重用性是衡量代码健壮性的一个标志，无论是函数，类，接口，还是其他更高层次的模型，都是为了提高其重用性。

3.可扩展性：可扩展性是应用框架一个最显著地标志，他意味着框架的能力具有可生长性。

其实arcmap也是一个可以扩展的框架，下面我们通过对arcmap的框架的研究来学习如何搭建自己的框架

首先我们打开arcmap编写一个简单的宏

宏命名为zoomin--实现一个简单的放大功能

 2 Dim imxdocument As imxdocument
 3 Dim penovlop As IEnvelope
 4 Set imxdocument = ThisDocument
 5 Set penovlop = imxdocument.ActiveView.Extent
 6 penovlop.Expand 0.2, 0.2, True
 7 imxdocument.ActiveView.Extent = penovlop
 8 imxdocument.ActiveView.Refresh

保存宏，在菜单--自定义--自定义模式--工具条新建工具条

我们在arcmap工具条看到一个新的工具栏，

在菜单--自定义--自定义模式--命令找到 --宏将我们刚才写的宏拖到菜单栏，这样我们就实现了一个简单的功能

如此可见arcmap是一个可拓展的框架

2.通过实现接口或者抽象类的方法实现arcgis功能

如图安装了arcgis后可以使用arcgis addin 来扩展功能
