用Mapx计算两个叠加图形的重叠部分的面积-MapX calculated using two superimposed graphics part of the area of overlap

基于物理的大气效果实时绘制，利用查询表的方法，对颜色进行实时的计算查找，可以用于大型的仿真系统中-Physics-based real-time rendering of atmospheric effects, using look-up table method for calculating real-time color to find, can be used in large-scale simulation system

VB＋MapX 实现图层的下拉功能.如打开中国地图,下拉至四川,再到成都地区地图-VB MapX realize the drop-down feature layers. Such as to open the map of China, the drop-down to Sichuan, Chengdu and then map

arcserver9.2安装与配置GIS开发的好帮手，不会的可以看看。-Installation and Configuration arcserver9.2 good helper GIS development will not take a look at the can.

GIS核心算法之一,线缓冲区生成,生成速度较快,效果也不错-GIS, one of the core algorithm, line buffer generation, to generate faster results would be good

ArcObjects开发实例，共分三个单元：  通过可视化编程工具，利用地图控件，对所选信息系统从数据准备与图层显示等方面进行二次开发。关键步骤包括：理解、运行已有实例；对实例进行修改，以简单直接的方式加入自己的数据；直接编程在程序中一层层地加入数据。  通过可视化编程工具，利用地图控件，对所选信息系统从地图缩放、比例尺与图层控制等方面进行二次开发。关键内容包括：图层缩放：左键放大，右键缩小；比例尺控制：显示比例尺，指定比例尺显示窗口，控制某些图层在一定比例尺范围之内显示；图层控制：关闭/显示图层，调整顺序。  通过可视化编程工具，利用地图控件，对所选信息系统从图文互查等方面进行二次开发。关键内容包括：按图查属性：点击查询，得到（唯一或多个）对象的属性；以属性查图形：从属性列表中（通过查询）选取对象，定位其空间位置。 -err
