Semantic web services (SWS) hold the promise of enabling dynamic discovery of candidate web services fitting a particular specified need. One interesting question is what impact this will have on software and systems engineering methods – will main

The introduction of AIS will change maritime surveillance in the future. We explore how satellites can complement or extend this cooperative surveillance technique. Radar satellites alone are not sufficient. Micro-satellites carrying sensors for rece

The Synthetic Aperture Radars (SARs) on ERS and RADARSAT are sensitive to changes in the small-scale surface roughness present on the ocean surface, which is altered by the velocity field associated with internal waves. More than 2600 SAR images from

Radar satellites are currently being used on a routine basis for near real‐time pollution monitoring in Norwegian waters. This article describes the phased introduction of this service, from infrastructure development, basic science, and field expe

Oceans constitute the majority of the Earth's surface. But in terms of surveillance, the ocean surface is a much simpler background for detection of man-made objects than is the ground. For this reason, it was no surprise that radar satellites went i

Evaluation of modelling languages is important both to be able to select the most suitable languages according to the needs and to improve existing languages. In this chapter, business process modeling notation (BPMN) is presented and analytically ev

Norway has used spaceborne SAR systems for operational fisheries monitoring since 1998. RADARSAT-1 has been the main source of data. With ENVISAT, there are plans to increase usage of satellite data. First, however, it is important to verify which mo

ENVISAT is planned to be launched in 2000, and will carry the Advanced Synthetic Aperture Radar (ASAR) as one of its main instruments. The ASAR will provide a diversity of imaging geometry and polarisation that has not yet been available from space b

Extensive near real time use was made of ERS-1 SAR images for pollution monitoring in Norwegian waters throughout 1993. This paper presents four rather different events which demonstrate the slick detection capability of ERS-1 under favourable wind c
