Due to their level of spatial detail (pixel dimensions equal to or less than 1 m), very high-resolution satellite images (VHRSIs) need particular georeferencing and geometric corrections which require careful orthorectification. Although there are several dedicated algorithms, mainly commercial and free software for geographic information system (GIS) and remote sensing applications, the qualit...

This paper describes the use of probabilistic graphical models, in particular Bayesian networks (BN), for the detection of two problem invasive alien plants, C. odorata and L. camara, from the recently-launched 8-band Worldview-2 satellite imagery acquired on 26 September 2010 over central Swaziland. The main objective of this work was to apply and evaluate the efficacy of the very high resolut...

Earlier research results have shown some potential of using high resolution satellite data, like QuickBird, for sea floor classification, but the number of bands have been a limiting factor. In this paper we present the results of a preliminary study of the use of WorldView-2 data for benthic cover classification in the Swedish archipelago. WorldView-2 is the first high-resolution 8band multisp...

Traffic monitoring in urban areas is a complex issue and recent Remote Sensing technologies can play an important role in planning and monitoring the urban environment.In this studya semi-automatic object-oriented workflow was designedto detect moving vehicles and their speed from single pass WorldView-2 multispectral data.The time lag in data recording between each spectral band causes a small...

Numerous studies have used various types of remotely sensed data to estimate forest biomass-related parameters such as basal area, volume, biomass, stocking etc. Some sensors have high spectral resolution such as ASTER or MODIS, but low spatial resolution whereas others have high spatial resolution, but low spectral information, such as IKONOS and QuickBird. Digital Globe’s WorldView-2 provides...

The present research highlights affiliation defenses in the psychological confrontation with death. In 3 experiments, it was found that mortality salience led to increased affiliation strivings, as indicated by a greater preference for sitting within a group as opposed to sitting alone. Mortality salience actually led to increased affiliation with a worldview-threatening group (Experiments 1-2)...
