Progressive vector transmission

Abstract

Progressive transmission of raster images over the World-Wide Web has been successfully applied to provide the user with coarser versions of the data before downloading a complete image. On the other hand, in the vector domain progressive transmission is challenging. Increasing the level of detail of a vector dataset does not simply imply adding pixels to it. In this paper, we discuss issues related to the progressive transmission of vector maps. We also describe a model for multiple representations of maps that can be transmitted progressively.
