Streaming geometry using quasi-pyramidal structure
First Claim
1. In a geographic information system (GIS), a method for streaming an object, the method comprising:
- receiving a request for the object for presentation along with other image data, wherein the object is described by an attribute;
determining a level of detail (LOD);
comparing the attribute to the LOD; and
selectively streaming the object based on a result of the comparison of the attribute with the LOD.

Abstract
Streaming data in a geographic information system (GIS). A request for an object is received for presentation of the object along with image data. The object is described by an attribute. A level of detail (LOD) is determined. The attribute can be compared to the LOD. The object can be selectively streamed based on a result of the comparison of the attribute with the LOD. The object can be received from a data storage and retrieval subsystem of the GIS system by a data manipulation and analysis subsystem. The streaming of requests and data between the data storage and retrieval subsystem and the data manipulation and analysis subsystem can take place over a network such as a local area network, a wide area network, and/or the Internet.
