HJW Maps “The Rock”
HJW GeoSpatial (HJW), Oakland, Calif., will create a photogrammetric map of Alcatraz Island.
Architectural Resources Group (ARG), a historical preservation architectural firm in San Francisco, Calif., contracted HJW for the project. The project will involve ground control, aerial photography, planimetric and topographic mapping to create a 40-scale digital map with 2’ contours of the island.
The project is scheduled to be completed by mid July, 2001.
