黄河的GIS地图，shp格式，方便ARCview学习者使用(GIS map of the Yellow River, shp format, to facilitate the use of ARCview learners)

利用点的数据，首先读入文件，然后构建TIN三角网(Using the point of data, first read the file, and then build TIN triangulation)

基于GIS的路灯管理系统，实现了地图浏览控制的基本功能。主要实现路灯的管理，检修，分析，决策等功能。(GIS-based street management system to realize the basic functions of the map view control. The main street to achieve the management, maintenance, analysis, decision-making functions.)

基于python语言的ARCGIS中shp图形文件的读取(SHP based on ARCGIS Python language of the graphic file reads)

说明：  arcenging实现最短路径分析（arcgis编程）(Arcenging for shortest path analysis (arcgis programming))

cass图层管理一个快速打开关闭图层的小插件很实用(cass layer management a quick opening and closing very practical small plug layer)

XYZ坐标转为GLOBK或者QOCA中的NEU，以及大地测量中大地线反解问题，即由经纬度解算大地线长度(convert XYZ coordinates into NEU in GLOBK or NEU, and geodetic earth line inverse solution, that solution by the latitude and longitude Geodetic Line length)

用matalb产生logisitc，tent，切比雪夫，改进型logistic四种混沌序列，同时产生Zadoff-Chu序列，并绘图比较几种序列间的自相关以及互相关性能。(Produced by matalb logisitc, tent, Chebyshev, improved logistic four kinds of chaotic sequences generated simultaneously Zadoff-Chu sequence, and drawing compare several sequences autocorrelation and cross-correlation properties.)

等值线区域填充，即由等值线构造等值面。本程序具有很强的实用性，并附有详细的程序说明文档和参考文献，相信对你将会大有裨益。(Contour area filling, which also means constructec isosurface from contour. This procedure is highly practical, with detailed description of the procedures documents and references, I believe you will boost.)

Douglas Peucker算法的matlab实现，应用于地图制图中的综合制图。其中有中国地图数据加以验证。可以自设threshold。(The matlab implementation of Douglas Peucker algorithm is applied to cartographic generalization in cartography. Among them, the map data of China is verified. You can set threshold yourself.)
