In September 2016, Stellenbosch Municipality and the Centre for Geographical Analysis (CGA) at Stellenbosch University embarked on a collaborative effort to share GIS data and services. As part of this collaboration, a comprehensive land audit for all properties within the Stellenbosch Municipal Area will be carried out. Phase 1 of this [...]


Terrain Analysis

Terrain analysis is defined as the study of the nature, origin, morphological history and composition of land forms, the result of which is a land form or land component map. Land components can be mapped by studying topographical maps, interpreting aerial photographs (Speight, 1977) and making field measurements (Graff and Usery, 1993). Such [...]



Cartography is the art and science of representing natural or anthropogenic features on a flat surface. As mapmakers, we understand that a map must be designed with attention to the audience and its needs and that the goal of a map is to assist the reader to discern its purpose promptly and effectively. The CGA [...]


Data capturing

Data capturing includes the collection or creation of spatial information for use in geospatial representation or analysis. Data capturing performed by the CGA can include tablet or on-screen digitising, scanning, manual database entry, field-work collection, and a wide variety of spatial data acquisition. Data capturing performed by the CGA can include tablet or [...]



GeoComputation involves geographical (spatial) analysis and modelling and typically includes the development of methods to model and solve a range of highly complex, often non-deterministic problems. The aim is to provide enabling technologies for quantitative geographical analyses and to overcome associated computational challenges. The CGA is actively involved in this field [...]



Orthorectification is the process of geolocation and terrain distortion correction of aerial or satellite imagery. Depending on the nature of the imagery, this process can involve the matching of identifiable points on the ground to their corresponding points on an image, often making use of specific camera calibration variables, aeroplane/satellite position and orientation [...]


Web Mapping Applications

Geographical Information Systems (GIS) has revolutionized geographic analysis and spatial decision support and has greatly enhanced our understanding of the real word though it’s mapping and spatial modelling capabilities. Although GIS software is becoming more powerful, less expensive and more user-friendly, GIS still remains the domain of a selected few who can operate [...]


Land Cover Mapping

For geographical information to be most effective in decision making it must be detailed, up-to-date and accurate (Benz et al. 2004; Carvalho et al. 2004). This also applies to land cover data, which is essential for decisions related to land evaluation (Kalogirou 2002; Van Niekerk 2008), urban and regional planning (Tapiador & Casanova [...]


Growth Potential Study of Towns

One of the objectives of the Department of Environmental Affairs and Development Planning (DEA&DP) of the Western Cape provincial government is to undertake spatial planning that promotes and guides the sustainable future development of the province and redresses spatial inequalities. This goal led to the development of the Provincial Spatial Development Framework (PSDF), [...]
