Due to urbanization, conversion to forest or agricultural land, but also atmospheric changes, heathland areas in Western Eu-rope started to decline from the beginning of the 20th century [1]. As a result, many heathland sites, among which Kalmthoutse Heide in Belgium, were included in the European Natura 2000 program, a network of protected areas all across(More)
This paper discusses the application of superresolution (SR) image reconstruction on multi-angle Chris/Proba images. The goal is to increase the spatial resolution of Chris/Proba images, with 18 bands from 0.4-1.0 ȝm in the hope to obtain a better ecotope classification. The SR approach chosen for this study is Total Variation [1], an iterative method which(More)
Uncontrolled, large fires are a major threat to the biodiversity of protected heath landscapes. The severity of the fire is an important factor influencing vegetation recovery. We used airborne imaging spectroscopy data from the Airborne Prism Experiment (APEX) sensor to: (1) investigate which spectral regions and spectral indices perform best in(More)
A new procedure for quantitatively assessing the geometric accuracy of thematic maps, obtained from classifying hyperspectral remote sensing data, is presented. More specifically, the methodology is aimed at the comparison between results from any of the currently popular contextual classification strategies. The proposed procedure characterises the shapes(More)
a r t i c l e i n f o Heathlands are man-made habitats and their decline during the last century can be contributed to shifts in both agricultural and management practices as well as to hydrological and atmospheric changes. As a result, many heathland sites, including the Kalmthoutse Heide in Belgium, were included in the European Natura 2000 program, a(More)
