In South Africa, spatial address data has been collected by different public and private organisations, with little or no cooperation on data sharing. Although there is weighty evidence about the benefits of spatial data sharing, organisations are still experiencing problems in making it happen, hence the costly duplication of efforts in data collection and storage still persists… (more)

Landslides and rockfalls, like most natural hazards, cannot be prevented but the effects thereof can be mitigated using sound engineering judgement. For this reason roads are generally constructed in such a way that steep slopes adjacent to the road are avoided and the risk that a landslide or rockfall will envelop the road is reduced. However, it is impossible to avoid all areas with uneven topography and inevitably when roads are constructed in mountainous terrains, cuttings into natural slopes are required to obtain a suitable alignment… (more)

GIS is the perfect tool for spatial modeling in a feature-dense area such as an academic campus. There are multiple relationships between features that have an impact upon how a campus operates, from walking distances between lecture theatres, green space management and facilities management for parking as examples.  By knowing what is where, it is possible to understand the spatial relationships within a campus and plan accordingly… (more)

A true giant among trees – the tallest known hardwood in the world – was discovered and mapped using a combination of lidar and GIS, the same technologies Forestry Tasmania uses on a daily basis for managing forests in Australia’s southern island state of Tasmania. The swamp gum, a eucalyptus, was nicknamed Centurion and measured at 99,6 m in height and 405 cm in diameter… (more)

Those of us in the GIS community take it for granted that the incorporation of GIS enriches effective asset management practices, to the point where we find it difficult to understand how good asset management could be practiced without GIS. In reality however, many government transportation departments report only limited success in both good asset management practice and incorporating GIS into their asset management practices. So, why the gap between promise and reality?… (more)

With more than 80% of all business information containing a location component, the use of location as an anchor for project management and information flow is a logical choice. This article will explore the emergence of GIS as a valued tool in the infrastructure and construction industries for its ability to address four broad business issues – data management, planning and analysis, field force enablement and situational awareness – and how construction, mining and services provider Thiess are using GIS to great advantage… (more)

First I want to thank the Royal Geographical Society for giving me this award and for recognising the role of geographic information systems (GIS) in geography. This is a milestone event for me and also for the GIS world that I am part of. Geography has been co-evolving with this interesting technology for some decades. In the last half of the twentieth century, a group of people began exploring what I like to call computational geography. This work involved people interested in exploration and geographic science… (more)

The emergence of GIS and the broader geospatial information market over the years has seen industry respond to technological developments, economic ups and downs and societal change in equal measure. Rarely have developments in the GIS industry conflicted with broader trends; instead the GIS industry has consistently responded to wider changes by adapting to them. This trend is most clear in the movement of geospatial data and tools onto the web… (more)

In the Eastern Cape Province there are still many schools that are lacking computing infrastructure and teacher competencies in IT. In addition, access to the internet is extremely uncommon and most teachers lack access to even basic communications technology such as email. Those schools that do have computer equipment are often using out of date hardware and software on these devices. Because of these issues, creating a successful programme for the tuition of GIS in schools is no easy task… (more)

While working for a former employee, we undertook some exciting supply chain work which combined crop models, historical rainfall data, GIS, storage capacities of grain silos, road and rail networks – multi-modal transport mechanisms, producer locations, consumer locations,  market prices of the commodities (SAFEX) and crop production areas. Supply chain analysis consists of a quantitative analysis of inputs and outputs between firms, prices and value added along a supply chain through agent accounts… (more)

Internationally there is a growing demand for persons competent in geographical information science (GISc). The US Bureau of Labour Statistics projected a growth of up to 26% in the GISc labour market. In South Africa, government departments are already experiencing vacancies in the region of 30%. This is not a new phenomenon, as long ago as 1998 the Department of Science and Technology, South Africa, identified geomatics as one of five technology focus areas for the ICT roadmap… (more)

GIS is integral to government operations and yet here in South Africa treasure troves of GIS data lie hidden in silo structures while various government departments and local municipalities blow their budgets hiring consultants to provide them with data that is actually freely available to them, if only they knew it was available and how to access it. Much of this needless expenditure is being duplicated across South Africa at a time of restricted budgets and increased demands for service delivery… (more)

The use of environmental geographical/geospatial information systems (GIS) is fast gaining momentum in South Africa.

Crime analysis also plays a role in devising solutions to crime problems, and formulating crime prevention strategies… (more)

The accurate positioning of voting stations within voting districts was an important factor in ensuring that the voting process proceeded smoothly on election day. Voting districts and stations were determined in accordance with provisions set out in the Electoral Act and focused on allowing the optimum number of voters unimpeded access to vote. Since 2004, the voters’ roll has grown by 2,5-million to 23,1-million and the IEC’s challenge was to analyse and amend voting districts and stations where necessary… (more)

Gone are the glory days when investing in an expensive new server just to run one piece of software could be justified. In the current economic climate, with IT budgets coming under closer scrutiny, any investment needs to be justified as a legitimate business need. Even for a GIS company that is dependant on extremely resource-intensive applications that typically require different platforms to run, justifying expenditure on separate servers for each new system can be difficult. And if the expense can’t be justified, “making do” with what they’ve got could mean lagging behind their competitors and losing traction in the market… (more)
