Patent Images
1. A spatial data service system comprising:
- a spatial data output client for making a request for spatial data to receive the spatial data and then outputting the received spatial data on a screen; and
a spatial data server for transmitting the spatial data to the spatial data output client in response to the request of the spatial data output client, wherein the spatial data server transmits the requested spatial data to the spatial data output client in a progressive manner.

Abstract
A spatial data service system includes a spatial data output client 10 and a spatial data server 20. The spatial data output client 10 progressively displays on a user'"'"'s screen spatial data which has been progressively received from the spatial data server 20. Thus, the user can save time required for confirming the spatial data. Further, time consumed for processing a request for additional spatial data, if any, can be reduced. Still further, since transmission of unnecessary data is efficiently avoided, a network load can be lowered, resulting in reduction of additional costs that might be caused due to the network load.
