ChinaMapShift

idw 反距离权重插值，直接在程序中调用即可(idw inverse distance weighted interpolation, you can call directly in the program)

中国黄土高原地图，矢量（shp）格式，可用arcmap打开。(Maps o of Chinese Loess Plateau)

中国湖泊分布地图，shp文件，这个很难找的，大家可以用作查询、分析和基于ArcEngine或MO二次开发使用(Chinese lakes distribution map, shp file, this is difficult to find, we can be used to query, analyze and secondary development based on the use of ArcEngine or MO)

说明：  C#写的基于Google Earth的二次开发。

这是一款破解版的GoogleEarth软件，方便好用，可以看到三维模型(This is a broken version of the GoogleEarth software, easy to use, can see the three-dimensional mode)

说明：  1、根据所给的中国版图数据 绘制显示基于北京54坐标系的经纬度数据 编写兰勃特投影转换程序，转换上述数据，并显示 编写墨卡托投影转换程序，转换上述数据，并显示 同时，要绘制相对应的经纬网格，网格间距5度 2、根据所给的世界版图数据 绘制显示基于WGS84坐标系的经纬度数据 编写墨卡托投影转换程序，转换上述数据，并显示 计算北京(116.4，39.8)到巴黎(2.2, 48.52)的大圆轨迹，并显示 同时，要绘制相对应的经纬网格，网格间距5度(1. According to the data of China territory Plot shows latitude and longitude data based on Beijing 54 coordinate system Compile lambert projection conversion program, convert the above data, and display Prepare Mercator projection conversion program, convert the above data, and display At the same time, to draw the corresponding longitude and latitude grid, grid spacing 5 degrees 2. According to the world map data given Draw and display longitude and latitude data based on WGS84 coordinate system Prepare Mercator projection conversion program, convert the above data, and display The great circle trajectory from Beijing (116.4, 39.8) to Paris (2.2, 48.52) is calculated and shown At the same time, to draw the corresponding longitude and latitude grid, grid spacing 5 degrees)

Civilization game source code in Java: This game is a single or multiplayer strategy game. The player’s character is depends on the ruler of a civilization. It is a simple java game which is also developed for Android device platforms. Yeah! This game supports the android mobile devices as well.

采集运动过程中三轴加速度，数据可用于简单的人体行为识别(APP can collect three-axis acceleration in motion process, and the data can be used for simple human behavior recognition.)

cad格式转shp格式，用c# + arcengine实现，可能有部分小问题，(cad format switch shp format, using c#+ arcengine to achieve, there may be some minor problems)

说明：  使用uni-app开发，当第一次访问应用程序，如果蓝牙没有开启，则要自动打开蓝牙。(Uni app turns on Bluetooth automatically)
