The growth of web and wireless of geographical information systems presents a new set of challenges for map
personalization services, because web and wireless mobile users of geographical information systems require
information that is directly relevant to the specific task in which they are engaged. In this paper, we propose to set up
user ontology for map personalization. Based on the user ontology, we put forward and adopt the cartographic
generalization for web map personalization visualization driven by user ontology, which remain or reduce online web
map description data according to user's interests and increase user's understanding of the web map. Based on this, we
set up automatic web cartographic prototype systems to generate web mapping on demand.
Schematic maps are effective tools for representing information about the physical environment and make user easy
navigate for wayfinding. Evidence have shown that identifying how many categories of directions in urban street
network environments, building taxonomy of branching points, and establishing a hierarchy of connecting roads will
help produce effective schematic maps to ease wayfinding. Taking road semantic information and user demands into
account, we first build the vector data model of hierarchy of connecting roads. Then we propose the four generalization
algorithm and show the framework of how to generate schematic maps. Finally, schematic map on demand is designed in
a concrete experiment, while keeping the topological consistency of the road network between original and schematic
map.
