[Termes IGN] temps réelRésumé : (auteur) As a result of the Real-Time IGS Pilot Project (RT-IGS) and the EUREF Real-Time Analysis Project (EUREF-RT), real-time GNSS satellite orbit and clock corrections to broadcast ephemeris, the so-called real-time broadcast corrections (BC), have become available for the application in precise point positioning (PPP). The realtime BCs are currently available in global as well as in regional reference frames. In this contribution the PPP usage and performances of these global and regional BCs are analysed for the Australian continent. We identify the limitations of the current regional BCs, which results in scale-induced biases, and show how they can be improved. We also present an alternative, more user friendly, approach for regional BCs. It provides PPP users with simple means to correct for the biases of the regional approach.

[Termes IGN] TasmanieRésumé : (Auteur) Recent technological advances in the field of radar remote sensing have allowed the deployment of an increasing number of new satellite sensors. These provide an important source of Earth observation data, which add to the currently existing optical data sets. In parallel, the development of robust methods for global forest monitoring and mapping is becoming increasingly important. As a consequence, there is significant interest in the development of global monitoring systems that are able to take advantage of the potential synergies and complementary nature of optical and radar data. This paper proposes an approach for the combined processing of Landsat and ALOS-PALSAR data for the purpose of forest mapping and monitoring. This is achieved by incorporating the PALSAR data into an existing operational Landsat-based processing system. Using a directed discriminant technique, a probability map of forest presence/absence is first generated from the PALSAR imagery. This SAR classification data is then combined with a time series of similar Landsat-based maps within a Bayesian multitemporal processing framework, leading to the production of a time series of joint radar-optical maps of forest extents. This approach is applied and evaluated over a pilot study area in northeastern Tasmania, Australia. Experimental outcomes of the proposed joint processing framework are provided, demonstrating its potential for the integration of different types of remote sensing data for forest monitoring purposes.

[Termes IGN] ressources naturellesRésumé : (Auteur) More than ever our planet requires new approaches, effective policies and innovative tools to better manage and protect our natural resources and the services they provide. The challenge we face is to create a future where the economy interacts sustainably with the environment and where people’s welfare and well being is considered along economic, environmental, social and cultural aspects. Today’s complex and interconnected issues greatly benefit from integrating information and knowledge from different disciplines to achieve enduring outcomes. Integrated spatial planning is a concept that makes use of enhanced knowledge and vastly improved technologies to explore development scenarios in a world of finite resources and to visualise trade-offs along the way. This paper discusses three key elements of spatial planning and illustrates their practical application using examples from New Zealand. A recently developed Integrated Spatial Decision Support System (WISE) is described and its potential use for place-based planning and decision-making discussed. The paper concludes with some lessons learnt and ideas for a ‘way forward’.

[Termes IGN] zone urbaineRésumé : (Auteur) Three-dimensional (3D) land development is common, especially in urban areas. Management of 3D land rights, restrictions and responsibilities (3D RRRs) is one of the most important challenges in current land - administration system, most of which are equipped with cadastres able only to maintain information in a 2D spatial information environment.
