 Founded
in 1946, Penfield & Smith is an engineering and surveying firm in
Santa Barbara, California. Mark Shadburn (right) is a GIS Manager, and
Claudia Muzzio (left), a GIS Specialist.
 A
recent project Mark and Claudia completed was digitizing information about
the drainage conduits in the City of Santa Barbara. Information on racks
and racks of paper maps was digitized. Printouts in hand, field crews
took GPS equipment to every manhole, catch basin, creek – every surface
entrance to the drainage – pinpointed its location and collected information,
like the diameter of the pipe, direction and angle of flow. All this was
entered into the computer.
 The
City's drainage is now mapped. It can overlay detailed air photos,
as shown at right. Each point in the map is queriable. This is very useful
in the City's quest to clean up creek and ocean pollution.
