GIS讲义2

中国沙漠以及黄土分布图，矢量(shp)格式。(The distribution map of desert and loess in China (vector) (SHP).)

说明：  成都市shp格式地图，带地理坐标系，内容详细。包含大量的地理信息。(Chengdu city shp format map with geographic coordinate system, detailed content. Contains a lot of geographic information.)

说明：  用matlab构建不规则三角网构建，里面有四个文件，后三个是函数(Using matlab to build Irregular Triangulation network, there are four files, and the last three are functions.)

Think of ASP Trojan hunt 思易ASP木马追捕(Think of ASP Trojan hunt Siyi, the ASP Trojans.)

说明：  本文针对滑坡预测预报这一复杂性问题提出一种基于前向反馈传播（BP）神经网络的预测模型，描述了滑坡系统输入输出之间的非线性关系。为克服 BP 网络后期收敛速度慢、易陷入局部极小点等缺点，以遗传算法（GA）和模拟退火算法（SA）相结合的方式即遗传-模拟退火（GSA）算法对网络权值进行优化。用该方法预测滑坡位移获得了较好的效果(In this paper, a prediction model based on forward feedback propagation (BP) neural network is proposed for the complex problem of landslide prediction. The nonlinear relationship between input and output of landslide system is described. In order to overcome the shortcomings of BP network, such as slow convergence speed and easy to fall into local minima, genetic algorithm (GA) and simulated annealing algorithm (SA) are combined to optimize the network weight. The method can be used to predict the displacement of landslides)

gud CV design. Beginners can learn how to create CV

显示栅格图层和矢量图层，用于ARCGIS二次开发，(good)

测量坐标后，绘制山区地貌,可以得到比较逼真的山区地貌(Measuring coordinates, draw mountain landscape)

新游戏常见错误处理方法：(最常见8条) 问1：---------- 各种未知错误如“配置不正确”或其他错误 ---------- 答1：下载并安装《Visual C++》运行库； (一般情况下只需下载2010版安装即可)(Common error handling methods for new games: (8 of the most common) Question 1: Unknown errors such as incorrect configuration or other errors Answer 1: Download and install the "Visual C++" runtime; (Normally, you just need to download the 2010 version of the installation.))

实现了ArCgis二次开发中的通过位置查询要素的功能，给大家做一个参考！(Achieve ArCgis secondary development of functional elements of the query by location, give you a reference!)
