说明：  本程序可以实现用c sharp编写的GIS图形中通过点击使2d点和图形变成3d图形的功能(this procedure can be achieved using the c sharp graphics prepared by the GIS through it so 2d point and graphics into 3d graphics functions)

师兄用VC写的由湿地DEM生成的三维模型，赋有纹理，可以动态漫游，地理分析。希望对搞GIS开发的朋友有所帮助。包含DEM和纹理数据，所以有点大，请耐心下载。(senior VC written by DEM wetlands generated 3D model, endowed with texture, dynamic roaming, geographic analysis. Hope to engage in the development of the GIS friends help. DEM contains data and texture, a bit, please download patience.)

matlab曲面拟合强烈向做实验数据处理的朋友推荐，该函数特别适合空间点的曲面拟合，matlab中对于此类数据点似乎只能用griddata差值计算，并且效果不怎么好；至于B样条拟合，其外扩数据点的选取不是一般的matlab用户所能掌握的，同时对于非网格数据的转换也是一个问题。。。(matlab surface fitting is strongly recommended to friends experiment data processing, the function surface fitting particularly suitable space point the matlab for such data points seems calculated only use griddata difference, and the effect is not very good As for the B-spline Article fitting the outer expanding selection of data points is not an ordinary the matlab user can master, while for non-grid data conversion is also a problem. . .)

说明：  vb+mapobjects进行二次开发，实现地图放大缩小，鹰眼等功能(VB + MapObjects for secondary development, map zooming and zooming, EAGLE-EYE and other functions)

pspice上课课件，满足初学者要求，十分实用(pspice class courseware to meet the requirements for beginners, very practical)

栅格化计算Hurst指数，用于水文、气象参数趋势的判断 水文、气象要素的时间序列分析中，一般下载到的程序是针对单个站点的H指数计算，得到的结果是单个H指数值 该程序实现时间序列栅格图像上每个点H指数的计算，得到的结果是单个栅格图像，栅格值是H指数值(a distributed pattern to calculate Hurst Index,the input is a series of grid datas, the output is a grid data each pixel value is a Hurst Index.)

百度地图嵌入的经典例子，适合学习地图嵌入的同学使用。(Baidu map embedded in a classic example, is suitable for the students to use embedded learning map.)

将大地坐标转换到大地空间直角坐标，即将大地纬度，大地经度，大地高转换到X,Y,Z,采用的是克拉索夫斯基椭球(Will the earth coordinate transformation to the space rectangular coordinate, the earth is the latitude and longitude of the earth, the earth high transition to the X, Y, Z, USES a carat SuoFuSi ellipsoid)

中国地图的shpfile文件，分为省界、省会城市，地级市界，地级市驻地、县界等(China map shpfile file, divided into provincial boundaries, provincial capitals, prefecture-level city boundary, prefecture-level city resident, county boundaries, etc.)
