1:100,000-Scale Topographic Contours Derived from Digital Elevation Models, San Francisco Bay Region, California: A Digital Database
By
Heather M. Wright and Carl M. Wentworth
|
Introduction This report presents a consistent set of 1:100,000-scale vector topographic contours for all eleven 30x60-minute quadrangles in the San Francisco Bay region for use in visualizing the topography and preparing maps of the region. The contours were prepared by contouring an areally continuous 30-m altitude grid (National Elevation Dataset, Jan., 1999), and differ from USGS hypsographic DLG's (available for only part of the region). The report consists of 26 numbered parts, which represent text, spatial data, and 1:100,000-scale map graphics. Most of the files are provided in two or three different digital formats. All files are available for download here. |
