Moving Objects

OGC has undertaken a variety of work efforts to place moving object tracking into the OGC web services architecture. Moving object identification and tracking is an important aspect of Intelligence, Surveillance and Reconnaissance (ISR). OGC's work is being aligned with that of NATO and MISB.


OWS-8 Analysis of OGC Standards for Supporting Mobile Object Processing Implementation (11-108)

Ingo Simonis

This document describes the usability of OGC services and encodings to implement the OWS-8 observation fusion and tracking thread in an abstract way. The real deployment and an actual perspective on the engineering and technology viewpoint can be found in OWS-8 engineering report OGC 11-134, ‘OWS-8 Tracking: Moving Target Indicator Process, Workflows and Implementation Results’. In addition, it describes an XMLSchema based implementation of the UML information models defined in OWS-8 engineering report “Information Model for Moving Target Indicators and Moving Object Bookmarks” (OGC 11-113). The report is also based on the results of the VMTI/GMTI and STANAG 4676 realization in the OGC concept of operations study; performed as part of OWS 8 and the EC cofunded research project Emergency Support System - ESS” (contract number 217951).

OWS-8 Tracking: Moving Target Indicator Process, Workflows and Implementation Results (11-134)

Rob Cass, Mark Simms

The scope of this report is to provide a description of services, data storage and data movement within the OWS-8 Tracking sub-thread. The paper outlines the development of Sensor Observation Services (SOS), a Web Feature Service(WFS), a Notification Service and a Web Processing Service (WPS) for generating track features. Additionally, implemented encodings will be discussed as examples and in comparison to the encodings detailed in (Simonis, 2011).

OWS-8 Information Model for Moving Target Indicators and Moving Object Bookmarks (11-113r1)

Ingo Simonis

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 Motion Video Change Detection (10-036r2)

Stan Tillman

This Engineering Report documents the development effort to build a Web Processing Service (WPS) to perform a change detection algorithm on two motion video streams. It will examine the WPS Motion Video Change Detection architecture from various viewpoints in order to describe its purpose, data models, functional decomposition, and interaction between distinct computational components.

OWS-7 Dynamic Sensor Notification Engineering Report (10-061r1)

Johannes Echterhoff, Ingo Simonis

This document is applicable to scenarios where moving sensors need to be tracked and their entry into an area of interest needs to be detected. The document presents a detailed discussion of different approaches for encoding tracked object position. Two approaches for implementing dynamic sensor tracking and notification are described, one based on the Sensor Alert Service specification and the other based on the Sensor Event Service specification. An overview of standards and specifications relevant for and related to dynamic sensor tracking and notification is provided.
