METHOD FOR REAL-TIME UPDATING GIS WITH CORRECTION OF GPS POSITION INFORMATION USING MULTIPLE WEIGHTING REFERENCE POINTS

摘要

The present invention relates to a method for updating the GIS in real-time by the GPS position information corrected by the weight of multiple reference points relates to, and more particularly to acquire in real time the coordinates of the survey points from the GPS receiver, and with specific reference point and the measurement point located closest to compensate this, the environmental condition is selected for the most similar to a certain reference point. And one using the coordinate values and the measured coordinates of the reference point is selected for a particular value, and calculating the error, and using the distance from the measurement point to the calculated error value is calculated by weighting the error corrected value, which was then used to correcting the coordinate value of the measurement point, the introduction of such a correction coordinates to update the GIS. ; In this way, because the error is similar to the error of the coordinate value acquired in the measurement point can be calculated, surveying the coordinates of the point more accurately corrected, and can update the GIS.
