Jun 2009 | Comments Off on Is spatial special?

It is sometimes suggested that spatial data is just another form of data that can now be maintained in a data base and that in reality there is nothing “special about spatial”. Nothing could be further from the truth. For example spatial data is not the same as integer, alphanumeric or symbolic data for a number of reasons. These are: spatial data is scale dependent: do I query for 37.3N 45.2W..or? spatial queries are endemically computationally expensive…

May 2009 | Comments Off on Flight evaluation of a ‘GADA’

For the final evaluation of a GPS attitude determination algorithm (GADA), it was determined its true performance in terms of its accuracy, reliability and dynamic response. To accomplish that, a flight test campaign was carried out at the Brazilian Flight Test Division (GEEV) to validate the attitude determination algorithm. In this phase, the measured aircraft attitude was compared to a reference attitude, to allow the determination of the errors…

Coastal navigation upgrade
The UK’s General Lighthouse Authorities (GLAs) have awarded a £4m contract to VT Communications for the upgrade of 14 Differential Global Positioning Service reference stations. The upgrade includes adding the capability to use modernised GPS signals that will be needed for tracking the future satellite navigations systems, Galileo and GLONASS. www.vtplc.com

Apr 2008 | Comments Off on Is Indian NSDI an example to follow?

Special characteristic of spatial data is that it can be shared and used for many other purposes than the one, for which, it was originally produced. To facilitate its efficient sharing and reuse, it needs to be properly managed in the form of infrastructure i.e. Spatial Data Infrastructure (NSDI). This is one of the reasons that many countries are developing National Spatial Data Infrastructure (NSDI). But the challenge of developing a successful NSDI depends largely on its implementation which is so significant that none of the two key stakeholder groups i.e. public or private sectors can address it at their own. Therefore, if efforts are made to implement such initiatives by only one of the key stakeholder groups then the result may be partially if not totally failure to get the tangible benefits truly intended from such initiatives. As an example, Indian NSDI is explored in this context.

Real-time traffic information to reach more than 83 million users
According to ABI Research, real-time traffic information services will reach more than 83 million paid or registered users worldwide by 2012. It sees three elements to the puzzle of providing truly useful traffic data for navigation systems.

First, the traffic data collection ecosystem is very complex. Infrastructure measurement systems (road sensors, cameras, radar, or loop sensors) are expensive and hard to install. A second challenge is traffic data aggregation. As the basic data becomes more available, the complex data derived from floating-car probes or predictive modeling will become the differentiator. But such data are harder to integrate into navigation routing. A third factor is market landscape. ABI Research expects INRIX and NAVTEQ/Traffic. com to become the two players in traffic data. www.gpsbusinessnews.com
