地理信息系统设计ArcView的二次开发.ArcView软件是一套辅助用户组织、维护、显示、分析和传播地图与空间信息的传输工具，它为用户提供了进行空间决策的框架，空间处理能力及建立数学模型 (geographic information system design ArcView the secondary development. ArcView software is a supplement to household organization, and maintenance, display, analysis and dissemination of maps and spatial information transmission tool, It provides users with a space policy framework, the capacity and space mathematical model)

GIS课程平时作业：Editing In ArcMap读书笔记(The GIS courses Assignments: Editing In ArcMap reading notes)

测绘行业的坐标转换程序 用于大地坐标系，空间直角坐标系转换 大地坐标系，直角坐标系转换(Mapping the coordinates of the conversion process industries for the geodetic coordinate system, Cartesian coordinate system conversion of space geodetic coordinate system, Cartesian coordinate system conversion)

去除镶嵌过程中的空值,可以进行修复空值等。(remove nan)

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)

说明：  用于IDL各个组件安置的学习代码，从中可以学习界面的构造以及各组件与功能结合(Learning code for placement of various components in IDL)

ArcGIS_World中对geodatabase的专题讨论，包括添加和删除FeatureClass等内容(ArcGIS_World geodatabase for the symposium, including adding and removing FeatureClass etc.)

最近几年，社会上地理信息系统和电子地图技术越来越受到大家的关注，很多单位和个人都投入了大量的人力和物力进行了相关的设计开发。在这些实际的开发问题中，我想就公交车换乘自动查询系统的核心算法的设计和分析做一个不成体统的研究，还希望同志们能帮我指正错误，帮助提高。(In recent years, the community of GIS and digital map technology is receiving increasing attention to the U.S., many units and individuals have invested considerable human and material resources to carry out the relevant design and development. In the development of these practical issues, I would like to change bus system automatically query the core of algorithm design and analysis不成体统to do a study, and also hope to help my comrades error correction to help improve.)

实现A*算法地图寻优路径问题，游戏地图采用网格地图。(Achieve A* algorithm maps the path optimization problem, the game map using a grid map.)

图像A中0表示水体，1表示植被，2表示裸地；B中4表示水体，2表示植被，1表示l裸地。 本程序将B的分类编码改成和A一致；以A为参考图像生成参考矩阵；计算总体精度和kappa系数。(Image A shows water body in 0, vegetation in 1, bare land in 2, water body in 4, vegetation in 2 and bare land in 1. In this program, the classification coding of B is changed to the same as that of A, the reference matrix is generated with A as the reference image, and the overall accuracy and kappa coefficient are calculated.)
