Quad maps are used to break up map into smaller more manageable segments. They are often used in cave projects to share the work of drafting maps among the participants. The following image illustrates a typical quad map.
This image shows a quad map for Groaning cave. In COMPASS the quads can be any size, any number of rows and columns. As you can see the quad grid can be rotated to match the cave. In addition, any conceivable number scheme can be used including letter-number, number-letter, letter-letter and number-number. Rows and Columns can be independently incremented or decremented and can start with any values. This makes it possible to create any conceivable quad scheme.
