The aim this focus group is to determine the status of GIS in three areas namely: tertiary institutions, secondary schools and the GIS industry. This research includes the level and availability of training as well as the usage of GIS in Africa with specific focus on South Arica.

The shape, gravity field and rotation of the Earth (the pillars of geodesy) are affected by mass transport and redistribution in the earth system (atmosphere, hydrosphere, lithosphere, cryosphere and the interior of the solid earth). In order to better understand the earth system processes and investigate mass transport associated with geodynamics, natural hazards and even climate change, a system that is capable of continuous measurement and monitoring small changes (characterising the inherent earth system processes) with unprecedented spatial-temporal resolution and accuracy is required. To this end, space geodetic techniques such as Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Navigation Satellite Systems (GNSS), Interferometry Syntetic Aparture Radar (InSAR), Satellite Gravimetry (e.g., CHAMP/GRACE/GOCE) and Radio Occultation (RO) have demonstrated such capability. The space geodesy focus group at CGIS conducts geodetic, geophysical and atmospheric research through the use of various data products derived space geodetic techniques and other fields that rely on space geodesy for their observations in collaboration with national and international research groups.
Spatial data infrastructures
Leader: Serena Coetzee Researchers: Antony Cooper, Ludwig Combrinck, Victoria Rautenbach, Wiafe Owusu-Banahene, Noh Tewolde, Samy Katumba, Dinao Tjia
A spatial data infrastructure (SDI) involves everything and anything that is required to make spatial data from various sources useful and available to a wide audience. This includes spatial data, technologies, systems (hardware and software), standards, policies, legislation, agreements, human and economic resources, institutions, organisational aspects and people, which have to be carefully orchestrated to achieve an SDI's objective. We research mainly technical aspects of an SDI, such as, geographic information standards, geoportals, sharing of address data and the use of volunteered geographic information in an SDI.
