Author:Veerasamy, Namosha; Grobler, MMDate:2015The merging of terrorism with the cyber domain introduces the potential for using computers and networked technologies in cyberspace to carry out extremist activities. Despite the current debate on whether cyberterrorism can be regarded as ...Read more
Author:Cooper, Antony KDate:Apr 2014This presentation provides an overview of a meta-language for land use classification. It also explains why land use can’t always be determined from imagery, and why land use is not the same as land cover, zoning or planning - though they ...Read more
Author:Cooper, Antony K; van Rooyen, MH; Clarke, DG; Liebenberg, ECDate:Sep 1987Geographically 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 the feature, which has ...Read more

Author:Busgeeth, K; Brits, A; Whisken, JBDate:Apr 2008The paper starts off describing some of the most common challenges faced by government in sourcing data on informal settlements. It then goes further providing an overview of past attempts and current practice in the monitoring of informal ...Read more
Author:Cooper, Antony K; Zietsman, HLDate:Dec 1999This paper describes the Spatial Entity Classification Standard (SpECS), which has been proposed as a standard for classifying digital geographical data in South Africa, for use in Geographical Information Systems (GIS). The paper begins with ...Read more
Author:Lunga, D; Ersoy, ODate:Jul 2012In hyperspectral imagery, low-dimensional representations are sought in order to explain well the nonlinear characteristics that are hidden in high-dimensional spectral channels. While many algorithms have been proposed for dimension reduction ...Read more
Author:Cooper, Antony KDate:Jun 1993The 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 standard is exacting. ...Read more
