On-demand mapping and integration of thematic data

Cartographic mashup is a powerful tool for users to visualize thematic data together with base maps, and it is increasingly popular due to the better availability of geodata. In current typical mashups, thematic data and base maps come from different providers without any connection between the data sets, and their scales are not synchronized. In this paper, we firstly explore the problems in such mashups and the potential linkages between thematic data and base maps, then propose a novel methodology to establish explicit connections between thematic data and base maps, and finally propose how to utilize them to generalise thematic data. We mainly aim at conveying our idea in this working paper; that is the paper concentrates on the feasibility of our methodology, and no implementation is presented.
