ABSTRACT:
A method for displaying a zooming operation on a display screen of a computing platform. The method includes retrieving data from a geographic data storage system, possibly located on another system, displaying a starting image that shows geographic features at a first scale with a first level of detail and then displaying an ending image that shows the same geographic features at a second scale with a second level of detail. Between the displaying of the starting image and the displaying of the ending image, at least one intermediate image is displayed. The intermediate image combines two component images of at least some of the same geographic features shown in the starting or ending image. The two component images in the intermediate image are at the same scale and are registered with respect to each other so that the same geographic features represented in the two component images coincide. One of the two component images in the intermediate image includes at least a portion of the starting image and is formed using data from a first layer of a geographic database. The other of the two component images in the intermediate image is formed using data from a second layer of the geographic database.
