Geospatial visualization performance improvement for contiguous polylines with similar dynamic characteristics

摘要

Techniques are disclosed for rendering geographic information system (GIS) data. A server component responding to a request for GIS data for a given area combines contiguous elements that share the same dynamic characteristics. For example, a map server may combine the polylines of contiguous road segments sharing the same current speed/congestion conditions. Doing so may greatly reduce the number of individual polylines that are sent to a client for rendering.
