Definition of Map, contig

Map, contig: A map depicting the relative order of a linked library of small overlapping clones representing a complete chromosome segment.

A contig is a chromosome map showing the locations of those regions of a chromosome where contiguous DNA segments overlap. Contig maps are important because they provide the ability to study a complete, and often large, segment of the genome by examining a series of overlapping clones which then provide an unbroken succession of information about that region.
