Data availability and requirements for flood hazard mapping
by Zelda Els, Aurecon, and Adriaan van Niekerk, University of Stellenbosch


This study investigated whether the existing data in South Africa is adequate for flood hazard mapping in rural areas. One-dimensional flood modelling can be carried out in some areas, but more investment is needed for the collection of data appropriate for flood hazard mapping... (more)
Augmented reality as an extension to utility GIS
by Gareth Nicholls, Powertech IST
This article examines the possibilities of extending current GIS used by the utility industries with that of augmented reality (AR) toolkits on smart devices. Smart devices are aware of their location, the direction they are facing and the inclination in relation to the horizon... (more)
Orthrectifying SPOT5
by Ivan Henrico and Chris Vlok, UNISA

Geometric distortions introduced in satellite imagery during the image capturing process are inevitable and occur for many reasons. Much of the distortion related to sensor irregularities are automatically corrected at ground-receiving stations. Orthorectification is required to remove such irregularities... (more)
