The SANBAG Data Management Office (DMO) currently maintains a variety of data. The data maintained by the DMO is largely dependent upon information contributed by local governments and transit operators within San Bernardino County and is therefore available to these organizations upon request free of charge.
Data is also available, on a limited basis, to the private sector depending upon availability of information and recovery of costs associated with staff time and materials.
Unless specified otherwise, the GIS data available for download is compressed and in ESRI Shapefile format. You will need to uncompress all files into the same directory in order to load the data into a GIS viewer. Viewers include ArcView, ArcExplorer (Free), and Google Earth Pro. (There may be viewing limitations with Google Earth Pro when using large datasets.)
SANBAG GIS uses California State Plan Zone V (feet), North American Datum 83 (NAD 83).
This data is for reference purposes only and is compiled from best available sources. SANBAG assumes no responsibility for errors arising from misuse of this map.
