Transformation and verification methods of GPS (global positioning system) coordinates and local coordinates

The invention relates to a transformation technique of two coordinate systems, discloses a transformation method of GPS (global positioning system) coordinates and local coordinates and aims to quickly transform GPS coordinate data into local coordinate data required by engineering applications. The method includes the steps of a, determining two known points A and B in a local coordinate system; b, connecting the points A and B into a straight line L; c, acquiring coordinate points A' and B' of the points A and B in a WGS84 (world geodetic system 1984) coordinate system by a GPS; d, connecting the points A' and B' into a straight line L'; e, calculating an included angle of the straight line L and the straight line L', namely a deviation angle of the local coordinate system and the WGS84 coordinate system; f, shifting the acquired GPS coordinates according to the deviation angle calculated in the step e in order to transform the GPS coordinates into local coordinates. In addition, the invention further provi
