Trust lies at the heart of any relationship and certainly at the heart of any business relationship. It flows from concepts such as ‘my word is my bond’ and ‘you reap what you sow’. It is also said that trust is hard won but very easily lost and then very hard to recover…
Valuation of real estate/ properties is in many countries/ cities the basis for fair taxation. The property value depends on many aspects, including the physical real world aspects (geometries, material of object as build) and legal/ virtual aspects (rights, restrictions, responsibilities, zoning/development plans applicable to the objects spaces). The aim of this study is to investigate the opportunities provided by the semantically rich 3D building and cadastral models for valuation and taxation. In this paper we investigate the following related aspects…

The most basic operation of a vessel monitoring system is to determine the location of the vessel at a given time, and periodically send this information, usually by satellite, to a monitoring station ashore. Most of vessels are tracked using the purple finder. This finder uses various satellites like Inmarsat, Globalstar and Thuraya for tracking the vessel. INMARSAT-C has been the most considered choice, since INMARSAT transceiver is already fitted onboard many ocean-going vessels as required by GMDSS (Global Maritime Distress and safety System).
Over the recent past, the vulnerability of Global Navigation Satellite Systems (GNSS) to interference has become a concerning issue (Mitch, 2011), (Pullen, 2012). Nowadays, illegal portable jamming devices are becoming popular to protect the user from being tracked by GNSS in their vehicle. These so-called personal privacy devices radiate different types of interference signals in the GNSS frequency bands and can make conventional receivers inoperable. Counter measures have to be taken to prevent strong interference from blocking the GNSS-receivers for safety critical applications.
