San Bruno Mountain Mapping 1:6000 BASEMAPS For mapping restoration and monitoring activities on San Bruno Mountain. Components: Aerial Photography, Boundaries (Habitat Conservation Plan, State and County Park), Digitizer Tablet Reference Points, Drainages/Ravines, North Arrow, Scale Bar, Topographic Lines (25' Contours), Transmission Lines and Towers Click on an coverage abbreviation in the map below to download a basemap for the coverage. Each map is a JPEG approximately 3 MB in size (will take about 7 minutes on a 56K connection.)

The nine coverages of San Bruno Mountain, outlined in red. The HCP Boundary is represented in green, the Park boundary in blue. Coverages Northeast Ridge (NR 1) Upper Valley (UV 2) Owl/Buckeye Canyons (OB 3) Southeast Ridge (SR 4) South Slope (SS 5) Hillside (HS 6) Radio Ridge (RR 7) Reservoir Hill (RH 8) Saddle (SD 9) Format and Printing Instructions The basemap set includes nine maps, each as an image (.jpg), approximately 3 MB in size. To maintain a 1"=500' scale (1:6000), the files should be printed at 10.5" by 16.25". These may be centered on 11"x17" paper, with margins along the 17" sides set to 0.25 inches, and margins along the 11" sides set to 0.375 inches. The maps print clearly in grayscale. Although color images are more clear, color printing can be inconvenient or expensive. 11"x17" color printouts may be laminated for repeat use with washable markers and for protection from mud and rain in the field.

Data Sources and Accuracy

AirPhotoUSA.com. Original Pixel Size: 1 meter. Photo Date: June 2000.	San Mateo County Parcel Map and GIS, from Terrabytes. In some cases this HCPboundary and the original HCP boundary, as mapped in the original document, may not exactly coincide. In other places, the boundary is accurate to within 50 feet.	Created by TRA Environmental Sciences, December 2001. Points form a 2000' grid ranging 20,000 feet East/West, and 14,000 feet North/South.	Mapped from original 1:6000 scale SBM basemaps, created in 1980's by TRA Environmental Sciences.	USGS DEM. Published 1970's, revised 1997.	Mapped from aerial photography. Transmission lines are shown as yellow lines, towers are shown as square nodes along the yellow lines (some are labeled “TOWERS” or “TOWER”).

San Bruno Mountain GIS Database

To submit hand-mapped restoration areas, monitoring efforts, or other data for inclusion in the GIS database for San Bruno Mountain, contact Patrick Kobernus at TRA Environmental Sciences (see contact information below). Maps of work completed on San Bruno Mountain can be digitized and added to the records of restoration and monitoring work on San Bruno Mountain. Maps of restoration work, non-native vegetation control, and biological monitoring are updated for each annual report, published in February of each year. Your data may be valuable and can be recorded and published in the annual report. Maps may be mailed either to TRA Environmental Sciences or to the San Mateo County Parks Department, c/o Sam Herzberg. Additionally, GPS data taken on San Bruno Mountain may be electronically transmitted to TRA Environmental Sciences.
