Multi-source map data processing method

The invention relates to a multi-source map data processing method, which comprises the following steps of (1) forming a map request path by using splicing parameters comprising token parameters, map range parameters, multi-source map parameters, image size parameters and image format parameters; (2) calculating ground resolution comprising slices or image maps, determining geographical range coordinates of a finally returned map in combination with the image size parameters, and adding generated service images to a multi-source map set; (3) traversing and fusing all images in the multi-source map set to obtain a finally returned master service image. According to the method, a bottom layer space-isolated data structure is adopted, various images are directly fused, multi-source map images or service image data are integrated, and static images and dynamic images are accurately fused.
