English abstract:
Many maps on the web do not provide any formal information on the cartographic processes at work in them, despite existing elaborate metadata standards. The key idea of the research presented in this paper is to use the program code of online maps to analyse the transformational processes applied to render them, and to infer cartographic metadata, such as projection or symbology specifications, from such an analysis. By using runtime code instrumentation, the data flow graph of each output element on the map is reconstructed and can be matched against a library of cartographic patterns. Using this method, cartographic processes implemented in informal program code can be annotated with appropriate metadata, and novel applications for retrieving and analysing online maps can be envisioned.
