Author:Mlangeni, P; Coetzee, MJ; Meiklejohn, CDate:Oct 2012The premise of this poster is to highlight the Living Lab approach adopted for the development of the Regional Spatial Profiler (RSP) component of the Integrated Planning and Development Modelling (IPDM) project. The RSP is showcased in this ...Read more
Author:Dudeni, N; Debba, PraveshDate:Oct 2008For this research, the researchers examine various existing image classification algorithms with the aim of demonstrating how these algorithms can be applied to remote sensing images. These algorithms are broadly divided into supervised and ...Read more
Author:Breytenbach, AndreDate:Oct 2016Conducted in the City of Tshwane, South Africa, this study set about to test the accuracy of DSMs derived from different remotely sensed data locally. VHR digital mapping camera stereo-pairs, tri-stereo imagery collected by a Pléiades satellite ...Read more
Author:Salmon, BP; Kleynhans, W; Van den Bergh, F; Olivier, JC; Wessels, Konrad JDate:Jul 2012In this paper, the internal operations of an Extended Kalman Filter is investigated to see if any useful information can be derived to detect land cover change in a MODIS time series. The Extended Kalman Filter expands its internal covariance ...Read more
Author:Lunga, D; Ersoy, ODate:Oct 2011Modern remote sensing imaging sensor technology provides detailed spectral and spatial information that enables precise analysis of land cover usage. From a research point of view, traditional widely used statistical models are often limited ...Read more
Author:Coetzee, M; Goss, H; Meiklejohn, C; Mlangeni, PDate:May 2014The purpose of this article is to introduce the development of the Regional Spatial Profiler – a spatial information and modelling platform – for the Department of Science and Technology. Based on the steps set out in action research, this ...Read more
Author:Salmon, BP; Kleynhans, W; Van den Bergh, F; Olivier, JC; Marais, WJ; Wessels, Konrad JDate:Jul 2011Time series derived from the first two spectral bands of the MODerate-resolution Imaging Spectroradiometer (MODIS) land surface reflectance product can be modelled as a pair of triply (mean, phase and amplitude) modulated cosine functions. ...Read more
Author:Lunga, D; Ersoy, ODate:Jun 2013Multidimensional embedding is a technique useful for characterizing spectral signature relations in hyperspectral images. However, such images consist of disjoint similar spectral classes that are spatially sensitive, thus presenting challenges ...Read more
Author:Green, Chéri A; Maritz, Johan; Van Huyssteen, Elsona; Oranje, M; Sogoni, ZDate:Jul 2019Enabling equitable social service delivery and promoting sustainable rural development remain key challenges within South African rural areas. Fiscal constraints, the high cost of social service provision and growing rural settlements ...Read more
Author:Kleynhans, W; Salmon, BP; Wessels, Konrad J; Olivier, JCDate:Jul 2013There has been recent developments in the use of hypertemporal satellite time series data for land cover change detection and classification in South Africa and in particular, the monitoring of human settlement expansion is of relevance as ...Read more
