OpenGIS tool pools data pulls

An OpenGIS Consortium Inc. team has created a quick Web mapping interface to merge information from multiple sources.

Working from the OGC Web Services 1.2 interface on varied notebook PCs, representatives of federal, state and local agencies last month collaborated with vendors to show how a simulated government emergency operations center might scope out fast-breaking local events. The imaginary events included a tornado, a white truck being sought by police and a hazardous spill on an interstate bridge.

The participants called up and merged maps, geographic information systems data, live webcam images, photographs, and demographic and tax parcel records to present a composite package of information to decision-makers and emergency responders.

Sam Bacharach, outreach program manager for the Fairfax, Va., consortium, said the consortium's use of distributed online data saves the work of collecting and centralizing data and ensures better accuracy.
