Moravec角点检测算法的VC代码

前方交会测量程序，给出目标的两个点坐标和方向角，通过测量算法求出目标交会的第三个点，广泛应用在大地测量等领域-Intersection measurement procedure, two points are given target coordinates and orientation, by measuring the algorithm the objective point of intersection of the third

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

工程测量学中前方交会的vb代码：已知A、B两点坐标，观测了角a、b，求P点坐标。用坐标反算AB方向的坐标方位角。-Engineering measurement science in front of the intersection of vb code: known A, B, two coordinates, the observation angle a, b, seeking a point P coordinates. Calculated by coordinates, the a
