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

A stylized dataset of topographic contours, intended for mapping (not analytical) applications. The source raster was aggregated, contoured, filtered for small pieces, simplified, corner-cut, and simplified again. The contours were generated from Robinson, N., Regetz, J., and Guralnick, R. P. (2014). EarthEnv-DEM90: A nearly-global, void-free, multi-scale smoothed, 90m digital elevation model from fused ASTER and SRTM data. ISPRS Journal of Photogrammetry and Remote Sensing, 87:2014, 57-67. Available at http://www.sciencedirect.com/science/article/pii/S0924271613002360.
