The program was named Walls in anticipation of a feature that was implemented only recently: the incorporation of complete map documents in the project database. The mapping software should support the creation of detailed cave maps that automatically track an ever-evolving survey database -- something that commercial CAD and illustration programs can't manage at all. New traverses will be averaged into the data set, possibly exposing blunders in old data. Therefore, it would be nice if we could quickly produce up-to-date maps, both for publication and field use, that are more than just computer-drawn line plots or crude passage representations. Ideally, the maps will show realistic passage outlines and complete decoration. I believe this goal has largely been achieved due to the availability of Scalable Vector Graphics (SVG), a standard format that allows Walls to share the task of creating dynamic cave maps with a commercial drawing program.
