The sponsors of the OGC Geo4NIEM Initiative and the Open Geospatial Consortium (OGC) invite interested organizations to attend the OGC Geo4NIEM Demo public webinar on Sept. 19, from 10:30-11:30 a.m. EDT. Geo4NIEM is an OGC initiative named Geospatial Enhancements for the US National Information Exchange Model (NIEM).

Working from a scenario in which a hurricane strikes New York City, the initiative's technology provider participants will show how enhanced geospatial capabilities enable situational awareness through the ability to identify, process, and comprehend critical information about an incident. OGC Geo4NIEM Initiative technology provider participants include OGC members Galdos, The Carbon Project, Luciad and ArdentMC.

In the demo, specific Information Exchange Packages (IEPs) from the Department of Homeland Security (DHS) are implemented using widely employed open standards to support rapid and flexible communication of geospatial information in cross-community information exchange domains such as public safety, emergency management and maritime operations oversight. The following two NIEM information exchanges were used for testing and demonstration in this project.

  • The NIEM Request for Information (RFI) exchange facilitates interagency processes involving requirements, tasking and information gathering activities that support data collection and awareness within intelligence, public safety, emergency management and response operations. A NIEM RFI exchange document provides the mechanism through which intelligence analysts and operations managers can request and receive relevant information for processing and analysis.
  • The NIEM Vessel Position exchange from the Maritime Domain supports the effective understanding of anything associated with global maritime that could impact the United States' security, safety, economy, or environment. NIEM facilitates this understanding through effective, timely sharing of vital, secure information among many key partners by representing vessels, people, cargo, and maritime locations and activities.

The Geo4NIEM OGC Initiative addressed specific functional requirements to meet the following objectives:

  • Develop recommendations to enhance the standard use of the OGC Geography Markup Language Encoding Standard (GML) with NIEM data exchanges.
  • Develop recommendations to enhance the use of NIEM External Adaptors for geospatial content, including GML.
  • Test and demonstrate use of embedded GML and adaptors within NIEM data exchanges.
  • Develop Architecture documentation and a fact sheet for the use of embedded GML and adaptors in NIEM data exchanges.
  • Develop Recommendations for the inclusion of a Geospatial Domain within NIEM.

Using GML opens up many opportunities to integrate NIEM applications with geospatial web services based on OGC interface standards such as the OGC Web Feature Service (WFS) Interface Standard. Web services that use OGC standards make it possible, for example, to: keep data current with updates from diverse sources; tailor data presentation (e.g. map styles) on the fly for different communities; and exploit powerful cloud based transaction services and processing resources. GML has become a "common language" for spatial communication in NIEM-related domains such as aviation, weather, urban modeling, hydrology and ocean observation.

After the webinar, a detailed Geo4NIEM OGC Engineering Report will be made available to the public on the OGC Public Engineering Report website.
