Abstract

Transmitting vector data over the Web is a challenging issue. Existing methods for vector delivery over the Web focus on progressive transmission techniques. Long standing problems in the formalization of dynamic generalization and the time needed for complex algorithms does not allow their implementation in real life applications. We propose a new method for data transmission over the Web based on tiles. We show that in client-server architecture the coordination of all involved parts can create an efficient way to transmit vectors. We describe the methodology of how we can implement the successful for raster data, tile-based method to tackle the particularities of vector data transmission.
