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.

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.

Ad-hoc processing of Earth Observation (EO) data available through online resources is gaining more and more attention. Expected benefits include - More versatile EO data access - More convenient EO data access - Consequently, broadened use and exploitation of EO data - An important step towards integration of EO data into automatic chaining and orchestration - More efficient EO data access: indicating the exact desired result and evaluating processing code close to the coverage data source (i.e., on the server) minimizes network traffic, one of today’s critical performance limiting factors.
OWS-8 Information Model for Moving Target Indicators and Moving Object Bookmarks (Engineering Report)		11-113r1	Ingo Simonis	2011-11-23
This report aims at providing an information model for the usage of video moving target indicator data (VMTI), ground moving target indicator (GMTI) and tracking information (STANAG 4676) in the context of standardized spatial data infrastructures compliant to OGC and ISO standards. If possible, precedence was given on using the OGC Sensor Web Enablement suite of standards, as this suite provides a homogeneous suite of standards to express sensor and sensor observation data in the context of OGC. This means that all encodings are based on Observation and Measurements version 2 (O&M) and implemented as an application schema according to the rules of Geography Markup Language version 3.2 (GML). An information model – so called ‘bookmark’ – to conserve the trace from a moving object back to the original base data is discussed briefly.

OWS 7 Engineering Report - Geosynchronization service		10-069r2	Panagiotis (Peter) A. Vretanos	2010-08-02
This candidate standard describes a service that allows data collectors to propose changes to be made to a data provider's features. A change proposal can be made to create new data or to modify/delete existing data. Proposed changes are reviewed (either manually or automatically) an are either accepted or rejected. Accepted changes are applied to the feature(s). The service also maintains a log of all changes applied to each feature that can be used for replication.
Summary of the OGC Web Services, Phase 8 (OWS-8) Interoperability Testbed		11-139r2	David Arctur	2011-12-19
The OGC Web Services, Phase 8 (OWS-8) Testbed was an initiative of OGC’s Interoperability Program to collaboratively extend and demonstrate OGC’s baseline for geospatial interoperability. The majority of work for OWS-8 was conducted from March to September 2011.
