Abstract:
Hybrid images merge the benefits of map views and satellite images. A geographic information system includes a geographic information server and at least one database containing a plurality of map views and satellite images. A decomposition module of the geographic information server decomposes the map views and the satellite images into at least high frequency components and low frequency components. A map view and satellite image hybridization module blends the high frequency components from the map view and the high frequency components from the satellite image. Then, the hybridization module combines the low frequency components of the map view with the blended high frequency components from both the map view and the satellite image to form a hybrid image. The hybrid image can subsequently be stored in a database of the geographic information system and/or served to a client device via a network.
