PE&RS May 2007

This month’s cover image depicts a Distributed Production Management System (DPMS)
based on GeoCue Corporation’s core project management system and GeoCue Web Server. This new system, developed in cooperation with URS Corporation’s Geospatial Technologies Team of Gaithersburg, Maryland. The backdrop graphic depicts a simulated Master Project view over the Tampa Bay area of Florida. The tiles represent project components such as LIDAR or Orthophoto work units. The fill color, corresponding to the checklist depicted in the lower left of the cover, depict the status of various project tiles being worked by a number of geographically dispersed contractors. Superimposed over the Master Project is an Internet Explorer view through the Master Project Web Portal of the project, allowing project status viewing from any location in the world with a simple web browser. For additional information contact Bob Ryan (bob.ryan@urscorp.com) of URS Corporation or Lewis Graham (lgraham@geocue.com) of GeoCue Corporation. The backdrop NaturalVue™ images were provided courtesy of MDA Federal (formerly EarthSat) of Rockville, Maryland (contact Jon Dykstra, jon.dykstra@mdafederal.com).
