GPEM's researchers are always making news. Please find details of our most recent activities below:

September 2009

Kasper Johansen's Mapping Banana Plantations from Object-oriented Classification of SPOT-5 Imagery in the September issue of Photogrammetric Engineering and Remote Sensing
The objectives of this research were to develop and evaluate an approach for object-oriented mapping of banana plantations from SPOT-5 imagery, and to compare these results to banana plantations manually delineated from high spatial
resolution airborne imagery.

Kasper Johansen's OPERATIONAL MAPPING OF THE ENVIRONMENTAL CONDITION OF RIPARIAN ZONES OVER LARGE REGIONS FROM AIRBORNE LIDAR DATA for the Laserscanning conference in Paris in September. It will also appear in the volume of the International Archives of Photogrammetry, Remote Sensing and the Spatial Information Sciences.
Riparian zones maintain water quality, support multiple geomorphic processes, contain significant biodiversity and also maintain the aesthetics of the landscape.

Clive McAlpine in ECOS Magazine: Linking Land Clearing and Drought to Climate Change
University of Queensland researchers have produced evidence for the possible link between land clearing and climate change in south-eastern Australia. The work is part of a broader climate modelling project – involving Land & Water Australia and the Queensland Climate Change Centre of Excellence – being managed by Dr Clive McAlpine.

Jonathan Corcoran in Geoworld: Mapping Urban Fires- What roles do weather conditions, events and disadvantage play?
Are disadvantaged areas, during a cold spell, on a public holiday, at an elevated risk of fire? A GIS-based research project provides concrete data to answer just such questions.

The Human Development Research Paper (HDRP) Series features recent research commissioned to inform the global Human Development Report, which is published annually, and further research in the field of human development. The upcoming Report is on the theme of human mobility and development. Read more

Efficient radiative transfer model inversion for remote sensing applications A simple method for efficient inversion of arbitrary radiative transfer models for image analysis is presented. The method operates by representing the shape of the function that maps model parameters to spectral
reflectance by an adaptive look-up tree (ALUT) that evenly distributes the discretization error of tabulated reflectances in spectral space. Read more...

An Integrated Field and Remote Sensing Approach for Mapping Seagrass Cover, Moreton Bay, Australia Creating accurate maps of seagrass cover is a challenging procedure in coastal waters with variable water clarity and depths. This paper presents an approach for mapping seagrass cover from data sources commonly collected by natural resource management agencies responsible for coastal environments. Read more
