WorldView-2 (WV-2) is DigitalGlobe's latest very high resolution optical sensor. Launched on October 8, 2009, and fully operational since January 5, 2010, it flies along a sun-synchronous orbit at an altitude of 770km. The sensor is able to acquire panchromatic imagery at 0.46m ground resolution (0.52m at 20° off-nadir) and multispectral images in eight spectral bands at 1.8m resolution. In add...

Since WorldView-2 (WV-2) images are widely used in various fields, there is a high demand for the use of high-quality pansharpened WV-2 images for different application purposes. With respect to the novelty of the WV-2 multispectral (MS) and panchromatic (PAN) bands, the performances of eight state-of-art pan-sharpening methods for WV-2 imagery including six datasets from three WV-2 scenes were...

Previous research studies have demonstrated that the relationship between remote sensing-derived parameters and aboveground biomass (AGB) could vary across different species types. However, there are few studies that calibrate reliable statistical models for mangrove AGB. This study quantifies the differences of accuracy in AGB estimation between the results obtained with and without the consid...

For the flooding seasons of 2011-2012 multiple space assets were used in a “sensorweb” to track major flooding in Thailand. Worldview-2 multispectral data was used in this effort and provided extremely high spatial resolution (2m / pixel) multispectral (8 bands at 0.45-1.05 μ m spectra) data from which mostly automated workflows derived surface water extent and volumetric water information for ...

Purpose The paper offers a dynamic theory of leadership development. Design/methodology/approach – The paper examines selected leadership literature through the lens of theory building blocks. It identifies the role of the ideal goal in leadership and its importance in developing the psychological aspect of leadership. Findings – The paper posits that leadership is a developmental process, whic...

Western psychotherapy and indigenous shamanic healing systems have both used psychoactive drugs or plants for healing and obtaining knowledge (called "diagnosis" or "divination" respectively). While there are superficial similarities between psychedelic-assisted psychotherapy and shamanic healing with hallucinogenic plants, there are profound differences in the underlying worldview and concepti...

It is not the intention of this paper to outline my research project per se, as this has been discussed in past papers (see Hawkins, 2007a, 2007b, 2007c). This paper highlights the argument for the importance of making explicit and connecting one’s own personal beliefs and understandings (theories) with one’s research. The intention of this paper is to address Patti Lather’s concerns and examin...
