With the increasing popularity of web-based map browsers, remotely obtaining a high quality depiction of cartographic information has become com- monplace. Most web mapping systems, however, rely on high-capacity servers transmitting pre-rendered tiled maps in raster format. That approach is capa- ble of producing good quality renderings on the client side while using limited bandwidth and exploiting the browser's image cache. These goals are harder to achieve for maps in vector format. In this work, we present an alternative client-server architecture capable of progressively transmitting vector maps in levels-of-detail (LOD) by using techniques such as polygonal line simplification, spatial data structures and, most importantly, a customized memory manage- ment algorithm. A multiplatform implementation of this system is described, as well as several performance and image quality measurements taken with it. |
