Precise Point Positioning from Combined GNSS

Fugro Marinestar G4+ PPP-RTK Developments
Currently there are four global navigation satellite systems (GNSSs) available: GPS, Glonass, BeiDou and Galileo. The satellites of these systems are used for positioning, and the accuracy is greatly improved if precise satellite orbit, clock and uncalibrated phase delay (UPD) corrections are available when using the precise point positioning (PPP) technique. Fugro operates a worldwide network of reference stations capable of tracking GPS, Glonass, BeiDou and Galileo systems. This network is used to calculate precise satellite orbit and clock corrections of all four constellations in real time for maritime applications. The corrections are broadcast to users by eight geostationary L-band... (read more)

Small Company, Big Ambitions

GIM Interviews Paul Bosman, CEO, CycloMedia Technology BV
CycloMedia Technology BV is a privately owned company based in Waardenburg, The Netherlands. The company exploits an in-house developed camera system for capturing urbanised areas from the road. In January 2006 Paul Bosman became CEO. He talked to us about his many ambitious plans. What are the main products and services offered by CycloMedia? Since the early nineties CycloMedia has built up experience in systematic mapping of urbanised areas on the basis of 360-degree images (so-called cycloramas). These images are captured from the road and at street level using a car as carrier of the camera system, including positioning and... (read more)

Good Governance, Good Geo-info

Essential Role for GI at all Levels
Where just two decades ago spatial data was mainly carried on paper maps, map and three-dimensional topographic data is now accessible via Google Earth. Where accurate positioning was once the professional pride of highly trained geodesists, we now see such services provided by GPS-based consumer products. This revolution in technological developments and demand for information implies the need for continuous upgrading of professionals: ‘lifelong learning’. Lifelong learning is relevant not only for the professionals concerned but also for their organisations. These are in a permanent state of flux in order to adjust to their continually changing envir-onment. This may flow... (read more)

Difference between Theory and Practice

GIM Interviews Dr Vladimir Gershenzon, General Director, ScanEx
The third international conference on "Earth from Space" took place from 4th to 6th December in Moscow, Russia, with the theme "Most Effective Solutions". This meeting, accompanied by a small exhibition, aims to provide a forum for the exchange of experience in the practical use of satellite imagery for a broad spectrum of applications. ScanEx, headed by Dr Vladimir Gershenzon, is the main inspiration behind the conference. We interviewed him there.<P> When, why and how was ScanEx established, and what are your main products and services?   After my graduation in 1980 I worked for several years at different institutes...

How Can Establishing a UAV Fleet Help Your Business Take off?

Best Practices in Drone Mapping
Read this interview with five pioneers in the field for insights into the best ways to introduce drones into your business model. Unmanned aerial vehicles (UAVs or 'drones') are increasingly becoming the solution of choice and have indeed proven to be a disruptive force across a multitude of industries in the past decade, including for the geospatial surveying profession. But will drones really provide all the answers to your mapping challenges? We interviewed five pioneers in the field to take us beyond the hype, explaining the lessons they have learned from the frontline and sharing their insights on the best... (read more)

The New Era of Mobile Scanning

GIM International Interviews Felix Reinshagen, CEO of NavVis
Indoor mobile mapping is well past the tipping point and is about to go mainstream. In this interview, Felix Reinshagen from NavVis shares his views on the future, including his confidence that there will be plenty more developments in automatically generated assets from reality capture, and how 3D scanning and the geospatial industry are set to impact the world in many respects. Felix Reinshagen is co-founder and CEO of NavVis, a company that was set up with the objective of bridging the gap between outdoor and indoor digital maps. Do you see laser scanning becoming a commodity in the near... (read more)

High-level Political Support Needed

GSDI and Land Administration within Europe
Administrative reform within Europe has had a tremendous impact on land administration all over the continent. Geo-Spatial Data Infrastructures (GSDI) may bring further improvements. The authors review land policy, land administration and the role of land information within society, and call for high-level political moves towards information sharing. Examples of administrative reforms within Europe are restoration of the primacy of politics, reduction in ministerial tasking to core business, and improving the output of public institutions by distance steering, decentralisation and de-concentration of institutions. Other methods of improving output include quality assurance programmes, special service projects, restoring democracy and reestablishment of... (read more)

Boundary Dimensions as Basis

Managing a Cadastral SDI Framework
Cadastral information is a fundamental layer in the Spatial Data Infrastructure (SDI) and many GIS systems use it as a base framework. The authors introduce an approach to improve and maintain the spatial accuracy of cadastral boundary geometry that can concurrently improve the geometry of referenced layers. A multi-purpose cadastre is the goal of most countries today and, in many, ‘metes and bounds’ define boundaries. This system evolved during a period when it was relatively easy to measure lines but very difficult to find the exact coordinate location of a point on the earth's surface. Boundary dimensions and reference to... (read more)
