Arx1
说明： 选取四个点，自动判断是否在一个平面上。同一个平面上。则绘制一个多边形。不在一个平面，则以前三个点为底面，构成一个椎体。支持Move等转换命令，存图与开图，实现Jig交互绘制等。(Four points are selected to automatically determine whether or not they are on a plane. On the same plane. Draw a polygon. If it is not in a plane, the first three points are at the bottom, forming a vertebral body. Support Move and other conversion commands, save and open maps, Jig interactive rendering, etc.)

GPR_Sim
GPRSim.net is a basic GPR time domain simulation tool. It is partially based in the transmission line model and allows up to ten layers to be simulated with frequencies ranging from 200 to 2000 MHz. It can be used to try out different real world survey scenarios and understand how different center frequency antennas could perform, as well as getting an idea of how the ground penetrating radar A-scan might look like in the given conditions.

城区地价动态监测与基准地价更新系统
以江苏丰县为例，展示了城区基准地价更新监测系统。
需要自行添加使用区域地价数据库（ArcGIS制作）。(Taking Jiangsu Fengxian County as an example, shows the monitoring system of the urban standard land price update.
Need to add the use of regional land database (ArcGIS).)
