  • Cooper, Antony K (University of Pretoria, 1993-06)
    The purpose of this dissertation is to assess digital geo-referenced information and standards for exchanging such information, especially the South African National Exchange Standard (NES). The process of setting up a ...
  • Sinvula, KM; Coetzee, S; Cooper, Antony K; Hipondoka, M (2012-10)
    During the 1990s Namibia marked the introduction and acceptance of desktop Geographical Information System (GIS) technology into various sectors at national, regional and local community levels. This technology quickly ...
  • Cooper, Antony K; Peled, A (International Cartographic Association, 2001-08)
    A user of geographical data invariably compiles their data base using core data sets obtained from various sources. They then integrate these together to meet their particular needs and build their own, value-added data ...
  • Olivier, JJ; Greenwood, PH; Cooper, Antony K; McPherson, DR; Engelbrecht, R (ASPRS Publications, 1990)
    Owing to the complex, inter-disciplinary nature of geographical information systems (GIS), and to the wide variety of commercial GIS software available, considerable effort is needed to select software and hardware which ...
  • Cooper, Antony K (Computer Society of South Africa, 1988)
    Geographical information consists of non-spatial information (alphanumeric) and spatial information (vector and raster), the relationships between the non-spatial information and the spatial information, as well as the ...
  • Cooper, Antony K (1989-04)
    Geographically referenced (geo-referenced) information consists of all information that refers to the human-environment system and that can be localized in space and time. This includes cadastral, topographic, hydrographic ...
  • Cooper, Antony K (CSIR, 1988-02)
    This paper describes a suite of programs that simulates the lighting effects of the sun or moon on the earth's surface. A digital terrain model (DTM) is typically a two-dimensional regular tessellation of some measured ...
  • Cooper, Antony K; van Rooyen, MH; Clarke, DG; Liebenberg, EC (CSIR, 1987-09)
    Geographically referenced (geo-referenced) information consists of all information that refers to the man-environment system and that can be localized in space and time. The basic entity of geo-referenced information is ...
  • Govender, Nicolin; Wilke, DN; Kok, S (Elsevier, 2015-09)
    Convex polyhedra represent granular media well. This geometric representation may be critical in obtaining realistic simulations of many industrial processes using the discrete element method (DEM). However detecting ...
  • De Villiers, JP; Bachoo, AK; Nicolls, FC; Le Roux, FPJ (2011-04)
    Omnidirectional camera systems are used to supplement RADAR in tracking small craft close in to the ship in a maritime environment. They can simultaneously track multiple targets to provide a more complete situational ...
  • Sivakumar, V; Tesfaye, M; Moema, D; Sharma, Ameeth; Bollig, C (IEEE International Geoscience and Remote Sensing Symposium, 2009-07)
    In this paper, researchers present the obtained first scientific results from CSIR-NLC mobile LIDAR (LIght Detection And Ranging) and its validation/comparison with other ground and space-borne measurements. The LIDAR ...
  • Van Zyl, TL; Ehlers, EM (2009-07)
    The Sensor Web as an open complex adaptive system exhibits many characteristics that are common to self organising systems. One of the characteristics of the Sensor Web is that of self-adaptivity in a changing environment. ...
  • Van Zyl, TL; Vahed, A; Mcferren, GA; Shabangu, P; Cwele, B (Conference Management Services, 2009-07)
    Scientific Workflows provides a technology that facilitates researchers by allowing them to capture in a machine processable manner the method relating to some research. This increases both provenance and repeatability of ...
  • Vieira, R; van den Bergh, F; van Wyk, BJ (PRASA 2008, 2008-11)
    This paper presents a fiducial-based approach to monitoring the movement of breakwater armour units in a model hall environment. Target symbols with known dimensions are attached to the physical models, allowing the recovery ...
  • Cooper, Antony K; Greben, JM; Van Den Bergh, F; Gledhill, Irvy MA; Cannoo, BR; Steyn, WJVDM; De Villiers, R (South African Conference on Computational and Applied Mechanics SACAM08, 2008-03)
    A variety of armour units are used to protect breakwaters, piers and other harbour infrastructure, serving both to absorb the impact of violent seas and to reduce overtopping. A common type of armour unit is the dolos. ...
  • Udahemuka, G; Van Den Bergh, F; Van Wyk, BJ; Van Wyk, MA (18th Annual Symposium of the Pattern Recognition Association of South Africa (PRASA), 2007-11)
    Land surface temperatures (LSTs) can be approximated from brightness temperatures observed from satellites. Estimation errors between observed brightness temperatures and a brightness temperature model of a given pixel ...
  • Olivier, JC; Araya, ST; Wessels, Konrad J (18th Annual Symposium of the Pattern Recognition Association of South Africa (PRASA), 2007-11)
    An Artificial Neural Network (ANN) is proposed to detect human-induced land cover change using a sliding window through a time-series of Moderate Resolution Imaging Spectroradiometer (MODIS) satellite surface reflectance ...
  • Prince, SD; Wessels, Konrad J; Tucker, CJ; Nicholson, SE (Blackwell Publishing Ltd, 2007-07)
    In semiarid regions the ratio of annual net primary production to precipitation, rain-use efficiency (RUE), has been used as an index of desertification. In a recent publication (Hein & de Ridder, 2006) it was proposed ...
  • Wessels, Konrad J; Prince, SD; Carroll, M; Malherbe, J (Ecological Society of America, 2007-04)
    According to the nonequilibrium theory, livestock grazing has a limited effect on long-term vegetation productivity of semiarid rangelands, which is largely determined by rainfall. The communal lands in northeastern South ...
  • Wessels, Konrad J (2006)
    This chapter describes the current condition of dryland systems with respect to the services they provide and the drivers that determine trends in their provision. Within the context of the mounting global concern caused ...
