Parsons-UXB Joint Venture on Kaho’olawe Island Reserve Demilitarization GIS

The 11x7-mile Hawaiian island of Kaho’olawe lies six miles off the west coast of Maui. The Navy used it from 1945 until 1990 for air- and sea-based target practice, leaving a trail of unexploded ordnance (UXO), from small arms munitions to 500lb World War II-era bombs and 1,500lb nuclear simulators.  Parsons-UXB developed an island-wide GIS to manage the clean up of unexploded ordnance (UXO). The GIS tracks the location, disposition and handling of every suspected unexploded ordnance item uncovered on the island, plus the location of any historically significant sites, natural resources or environmental hazards. The goals of the new project were to:


Farallon delivered a web solution that presents up-to-the-minute GIS and tabular data, without translation or reformatting of project data, from data warehouses that are being updated on a daily basis.  Farallon designed, delivered, installed, tested, and tuned the web solution on budget and on time, despite an extremely aggressive contract schedule of less than six weeks from contract signing to delivery.  Kaho’olawe was divided into a grid containing 10x10 meter units.  Using a web interface, users who click on a grid square get a summary of information at a glance, while those who click on a piece of UXO get information and photographs about that item. The database includes more than 89,000 pieces of UXO with attributed GPS coordinates and images depicting everything from vegetation to the destruction date of ordnance in a particular grid square.

Subsequently, Parsons hired Farallon to install, configure and migrate Parsons-UXB’s spatial data and spatial data management workflows into an Oracle Spatial database.
