Summary:The invention discloses a satellite map target object contour identification method. The method comprises of (1) obtaining a designated area satellite map; (2) identifying a mask pattern; (3) obtaining the poi contour information; (4) splicing poi mask patterns; (5) identifying the poi mask patterns; and (6) obtaining the area, boundary set pixel points and center set pixel points of the related graph contour through an image processing technology, and calculating the complete area of the contour according to the corresponding proportion. According to the method provided by the invention, thetarget object contour data of the designated area can be automatically identified, the required data comes from the Internet, purchase and application are not needed, cost is greatly reduced, and efficiency is further improved, and meanwhile, the data is mainly acquired from the map service provider, so accuracy and the real-time performance of the data are ensured, and the building contour data information can be relativ
