This question pertains to mapping arbitrary data using web map tile technology.
Most of the time the data source for a web map is spatial in nature (OSM).
I'd like to create a site map using the cartographic sense of the word. Rather than a boring list of links I'd like to model a site map after cartography from the Metro in Washington DC. This could be used as a sort of alternative to a standard navigation bar.
Is it possible to churn any old image/vector into a set of tiles at different zoom levels, if I were to say, draw vectors manually with inkscape?
