Method for mapping by using virtual control point coordinates and elevation data

The invention discloses a method for mapping by using virtual control point coordinates and elevation data, and relates to engineering surveying application. The method comprises the following steps: S1, selecting at least one high-precision control point in a measurement area, and calculating a difference value # imgabs0 # between an actual elevation anomaly and a model elevation anomaly according to related data of the control point, S2, setting N virtual control points in the measurement area, and calculating a difference value # imgabs0 # between the actual elevation anomaly and the model elevation anomaly according to the difference value # imgabs0 #; and S3, performing mapping operation according to the longitude and latitude coordinates of each virtual control point and the normal height # imgabs1 #. 利用虚拟控制点坐标和高程数据进行测图的方法，涉及工程测量应用。本发明的方法包括以下步骤：S1、在测区内选定至少一个高精度的控制点，通过该点的相关数据，计算实际高程异常与模型高程异常的差值#imgabs0#：S2、在测区内设定N个虚拟控制点，获取和测定各虚拟控制点的相关数据：S3、根据各虚拟控制点的经、纬度坐标和正常高#imgabs1#，进行测图操作。
