净面积计算工具

该程序实现PCA的分类功能，程序后面有详细的解释，经检测，程序能够跑通(The program realizes the classification function of PCA. The program is explained in detail later. After testing, the program can run through.)

百度地图切片，VS2010版，可以切下来地图，长时间切图会有问题，注释很多，大家看后就能理解。(Baidu map slices, VS2010 edition, can cut down the map, cut figure there will be a problem for a long time, notes a lot of, everybody can understand.)

一些GIS计算公共方法 判断两个矩形是否相交 判断两个线段是否相交 判断点是否在面内 判断线与面是否相交 判断线与矩形是否相交 判断点是否在线上 计算线段的地理方位角(GIS calculation method to determine some of the public to judge two rectangles are intersected to determine the intersection point of two line segments are in the plane to determine whether the line intersects with the surface to determine whether the line intersects with the rectangle is calculated to determine the point whether the line segment on the geographical azimuth)

使用API接口，实现了机器人自动对话程序，简单的AI应用程序。(Robot Dialogue Program, Simple AI Application Program)

这是一个简单的AE搭建的arcmap的平台，有一些基本的功能(This is a simple AE-built ArcMap platform with some basic functions)

校园GIS系统，自己完成的校园浏览查询系统，没有数据。(GIS System of School。)

说明：  这是Python关于机器学习经典实例第12章的代码，，，可视化数据(This is the Python code for Chapter 12 of the classic machine learning example, ,, Visualization data.)

ArcGIS Engine 开发从入门到精通源程序2(共4)(Development of ArcGIS Engine from Initial to Proficient in Source Program 2 (4))

说明：  粒子群算法（以下简称PSO）就是模拟鸟群觅食行为的一种彷生算法 。 解=粒子=鸟 (鸟的位置象征着离食物的距离，粒子的位置也象征着离最优解的距离，是评价解质量的唯一标准)， 找食物=找最优解，一个西瓜=一个粒子找到的历史最优解，一块肉=整个粒子群找到历史最优解 ，(Particle swarm optimization)

说明：  Pywavelets的cwt函数做连续1维小波变换的时频分析，并图形显示(Time and Frequency of Continuous 1-D Wavelet Transform and Graphic Display)
