Content oriented copyright display

摘要

A server supporting mapping applications serves map data to a client device. The map data includes one or more references to copyright information about a feature or image in the map data. The reference may be used to locate the copyright data when the feature is requested and the copyright information is also served to the client device. Alternatively, copyright information can be associated with a tile that includes some or all of the features. When map data contains copyrighted content, a size threshold of the feature or zoom level can be used to determine if the copyright information is to be displayed.

主权项

1. A computer-implemented method executed on a computer server for associating copyright information with map data for use on a display device comprising:
receiving a request for map data from a client device; selecting, using the computer server, at least a tile of vector map data for transmission to the client device, responsive to the request for map data; associating copyright information with the tile of vector map data including providing a lookup table having a feature identifier for an individual map feature and a reference to corresponding copyright information; sending the tile of vector map data to the client device; and sending the copyright information as a separate text object as the tile of vector map data to the client device so that the client device determines whether at least a portion of the individual map feature being displayed on the client device exceeds a threshold size and dynamically updates copyright information displayed on the client device based on the portion of the individual map feature.
