In order to realize aerogeophysical data service quickly and effectively, the authors studied the Douglas Peucker pumping dilute algorithm and map optimization configuration technology according to characteristics of the track line data. On the basis of the requirements of aeromagnetic survey technical specifications to the yaw pitch, the authors diluted the coordinates to about 1% of the original under the premise of ensuring the basic remain unchanged by setting the thinning thresholds. After the stratification of track line and test area by the measurement scale, the maximum scale of the test area and the minimum scale of the track line were set up, so that the tracks can be clearly distinguished when the scale is larger than a certain scale, and area graphics can be shown only when the scale is smaller than a certain measure. The application of the technology of the thin line extraction and map optimization makes it possible that track line data do not have to be loaded into the computer memory, which accelerates the search speed of the track line and can achieve a fast and effective way to provide flight route data services.
