GIS and the San Francisquito Creek Project
A geographic information system (GIS) plays a key role in the San Francisquito
Creek Project. The GIS brings together digital data from the broad fields
of geography, cartography, hydrology, biology, and geology. This powerful
tool allows us to better understand and analyze the San Francisquito Creek
watershed and is a useful aid in evaluating issues and making decisions.
The GIS Database Project provides an
in-depth description of the development of the GIS database for the San
Francisquito Creek Project.
To learn more about the USGS, digital data available for the watershed,
and how a GIS is applied to the San Francisquito Creek Project,
please view the following PowerPoint presentation. The presentation
is available in two formats, but it is best to view in PPS format.
