Management Summary OWS-8 Information Model for Moving Target Indicators and Moving Object Bookmarks (Engineering Report)
application schema according to the rules of Geography Markup Language version 3.2 GML.
The mapping of GMTI, VMTI, and Track Model can be done following different OGC traditions by implementing it as a GML application schema using either base
GML types, using SweCommon as well as base GML types, or using SweCommon wherever possible. All three approaches shall be executed to test their applicability.
All target indicator and tracking data is provided in the form of Key-Length-Value encodings. KLV Key-Length-Value is a byte-level data-encoding standard used for
binary data byte-packing and metadata embedding into video feeds. Data is encoded into Key-Length-Value triplets, where Key identifies the data, Length specifies the
datas length, and Value is the data itself. It is defined in SMPTE 336M-2007 Data Encoding Protocol Using Key-Length Value, approved by the Society of Motion
Picture and Television Engineers. KLV encoding protocol defines a data structure, which is independent of the application or transportation method used. In contrast,
OGC preferred encodings make use of the extensible markup language XML. The goal of the work presented here was to develop a consistent conceptual mapping
between incoming KLV data and XML encoded data provided at OGC service endpoints. The implementation of the data conversion as well as synchronization
aspects between video or radar data with corresponding metadata was not subject of this work. A potential service portfolio to handle VMTI, GMTI and Tracking data is
documented in OGC Engineering Report 11-134.
