基于.Net 的开源的GIS开发环境与工具，具有处理电子地图的基本功能。(he backup is from a Sql Server 2008 Db in compatibility mode 90 (Sql Server 2005)- You will need to restore to a version of Sql Server 2008. It contains release versions of the MsSqlSpatial trunk and the data from the Countries/Rivers/Cities shapefiles)

在mapinfo中画基站的扇区的小程序（源码实际上是Mapbasic编的）(Mapinfo draw at the base station sector in a small program (source code are in fact made of MapBasic))

实现GIS计算机地图制图中画点线面功能(Implementation of GIS computer cartography point line in the drawing function)

本代码是使用lstm进行时间序列预测，能够很清晰的说明如何使用lstm(Time series prediction using LSTM)

说明：  Python source SNAP7 lib

说明：  python写的手写数字识别，建了一个CNN的神经网络(python Handwritten digit recognition)

说明：  基于视觉的巡线代码，用于直线跟踪以及检测，并输出预测的角度(this is used to follow a fixed line in openmv)

说明：  基于DOA的水声网络目标定位方法,首先利用MUSIC算法进行测向,再利用最小二乘法进行融合以定位。(DOA based underwater acoustic network target location method, first use music algorithm for direction finding, then use least square method for fusion to locate.)

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：  包含的是shp格式海图。完整的海图包括了数据信息。(Shp format that contains the chart. Complete chart, including the data.)
