Summary and Recommendations of the Geospatial Enhancement for the National Information Exchange Model (Geo4NIEM) Interoperabi    13-054r1  Richard Martell 2013-11-07
Geospatial information technologies are increasingly a foundation for supporting Information Sharing Environment (ISE), homeland security (HLS), homeland defense (HLD), law enforcement (LE), emergency management (EM) and public safety missions in the US. The inability to transport, deliver and exchange geospatial information for critical geospatial assets increases the risk to the nation. Many ISE HLS/HDS/LE mission partners have developed stand-alone geospatial information systems (GIS) or Common Operating Picture (COP) applications to support their stakeholder communities during incidents and for daily operational support. While different missions, these GIS/COP capabilities rely upon much of the same data or generate specific data during an event. The data are often stove-piped and not exposed to a broader community that could benefit from these data, resulting in duplication and delayed or incorrect decisions. While mission partners do not need to use the same GIS/COP tools, they could benefit from shared access to the common operating data and services used within these systems if they were exposed and exchanged using open standards. Under the auspices of the Program Manager for the Information Sharing Environment (PM-ISE), an identified government-wide information sharing shortfall will be resolved by funding work to enhance the National Information Exchange Model (NIEM). The focus of this work is to further enhance the framework’s geospatial exchange capability in light of guidelines and standards issued by the Open Geospatial Consortium (OGC) so as to significantly improve inter-government information sharing.

OWS-9 Aviation Portrayal Engineering Report    12-151  Daniel Balog, Roger Brackin, Robin Houtmeyers 2013-02-06
This document provides an overview of the portrayal work within the OWS-9 Aviation thread. Using open standards, a web services architecture was designed and prototyped to enable the retrieval of static airport maps in support of an ePIB. An ePIB, or Digitally Enhanced Pre-Flight Information Bulletin, provides the pilot with an easy-to-interpret representation of any relevant aeronautical and meteorological events that are likely to affect the flight, expressed as Digital NOTAMs. The static airport maps are an important part of an ePIB and should provide a graphical representation of the status of departure and arrival airports, showing only NOTAMs relevant to the particular context and represented geographically so that the effect of the NOTAM is clear. This approach avoids the pilot scanning through pages of textual description for potentially relevant NOTAMs, reducing the workload and the risk of missing a critical piece of information.

OWS-8 AIXM 5.1 Compression Benchmarking    11-097  Jérôme JANSOU, Thibault DACLA 2011-12-19
AIXM stands today for the de-facto standard for Aeronautical Information Publication, used by air control service providers from Europe, USA and Australia. With version 5.1, it reaches a level of maturity allowing the support of Digital NOTAMs, as the first official version of these messages was published this year. In a near future, AIXM will be carried inside WFS requests but also into notification messages along WS event services. This last channel will be the one dedicated to D-NOTAMs. As D-NOTAM is aimed at aircrafts pilots, their transmission to the aircraft will use air/ground data link. Today, datalink communications lack bandwidth and future datalink will still have a limited capacity.

End to End Discovery and Access Engineering Report GEO Architecture Implementation Pilot, Phase 2  1.0  09-182r1  Josh Lieberman 2010-02-16
This Architecture Implementation Pilot, Phase 2 Engineering Report (AIP-2 ER) describes the practice of deploying, documenting, and registering contributed resources from the point of view of classes of GEOSS users who rely on GEOSS to support discovery and access to those resources. It emphasizes two paradigms for the GEOSS Common Infrastructure: 1) Service-oriented infrastructure for development of service-based community applications by technically advanced users; and 2) Content-oriented search facility and Web-based access mechanisms for end-users with a range of technical skills and domain knowledge. "End-to-end" here refers to the bidirectional connection between desired discovery practices and goals on the user end; and the required resource interfaces and documentation on the provider end.
