A stylized topographic data set of Baja California and adjacent areas.

A stylized dataset of topographic contours for mapping (not analytical) applications. Data were aggregated, contoured, had small pieces were removed, simplified, corner cut, and simplified again. The contours were generated from Robinson, N., Regetz, J., and Guralnick, R. P. (2014).
