Detecting the effects of hydrocarbon pollution in the Amazon forest using hyperspectral satellite images (2015)
Journal Article

The global demand for fossil energy is triggering oil exploration and production projects in remote areas of the world. During the last few decades hydrocarbon production has caused pollution in the Amazon forest inflicting considerable environmental...

Integrating user needs on misclassification error sensitivity into image segmentation quality assessment (2015)
Journal Article

Innovative technologies for terrestrial remote sensing (2015)
Journal Article

[In lieu of abstract, extract from first page] Characterizing and monitoring terrestrial, or land, surface features, such as forests, deserts, and cities, are fundamental and continuing goals of Earth Observation (EO). EO imagery and related technol... Read More about Innovative technologies for terrestrial remote sensing.

Airborne LiDAR for the detection of archaeological vegetation marks using biomass as a proxy (2015)
Journal Article

In arable landscapes, the airborne detection of archaeological features is often reliant on using the properties of the vegetation cover as a proxy for sub-surface features in the soil. Under the right conditions, the formation of vegetation marks al... Read More about Airborne LiDAR for the detection of archaeological vegetation marks using biomass as a proxy.

Forest disturbance and regeneration: a mosaic of discrete gap dynamics and open matrix regimes? (2014)
Journal Article

Question: Recent research in boreal forest suggests that an ‘open matrix’ model may be more appropriate than the traditional model of spatially discrete gap dynamics for describing forest disturbance and regeneration, but what is the evidence from te...

Size and frequency of natural forest disturbances and the Amazon forest carbon balance (2014)
Journal Article

Forest inventory studies in the Amazon indicate a large terrestrial carbon sink. However, field plots may fail to represent forest mortality processes at landscape-scales of tropical forests. Here we characterize the frequency distribution of disturb... Read More about Size and frequency of natural forest disturbances and the Amazon forest carbon balance.

Assessing the accuracy of volunteered geographic information arising from multiple contributors to an internet based collaborative project (2013)
Journal Article

The recent rise of neogeography and citizen sensing has increased the opportunities for the use of crowdsourcing as a means to acquire data to support geographical research. The value of the resulting volunteered geographic information is, however, o...

An overview of recent remote sensing and GIS based research in ecological informatics (2011)
Journal Article

This article provides an overview of some of the recent research in ecological informatics involving remote sensing and GIS. Attention focuses on a selected range of issues including topics such as the nature of remote sensing data sets, issues of ac...

One-class classification for monitoring a specific land cover class: SVDD classification of fenland (2007)
Journal Article

Remote sensing is a major source of land cover information. Commonly, interest focuses on a single land cover class. Although a conventional multi-class classifier may be used to provide a map depicting the class of interest the analysis is not focus...
