GIS and BIM integration will transform construction

An unfortunate fact of the architecture, engineering, and construction (AEC) industry is that, between every stage of the process, from planning and design to construction and operations, critical data is lost. GIS and BIM integration is about to change that. The reality is, when you move data between phases of, say, the usable lifecycle of […]

Interoperable plant design to optimise production facilities

This article looks at how 3D modelling and isometric generation capabilities were used to revive dated production facilities and enable increased efficiencies within a smaller footprint. The AUD65-million Tanami Expansion Project upgraded throughput for the Tanami gold mine, which is owned and operated by Newmont Tanami in the Northern Territory of Australia. The owner’s goal […]

Multidimensional poverty mapping of the Gauteng City Region

Following the Gauteng City Region Observatory’s (GCRO) earlier multidimensional poverty map based on 2013 data, this article presents an update based on Quality of Life Survey IV (2015/16) survey data to show how a multidimensional poverty map of the Gauteng City Region was created. Poverty is often measured in terms of income. An alternative approach […]

Visual analysis best practices

This article outlines simple techniques for making data visualisation useful and aesthetically pleasing. It does not provide instructions for building visualisations, but provides tips for making visualisations more effective. The difference between a good visualisation and a great one is that a great visualisation helps you understand more about the data more quickly. There are […]

Crowdsourcing the impact of global change on risk and vulnerability

The ability to respond to the impacts of global change on vulnerable populations and assets hinges on the availability of accurate and current information. Through the South African Risk and Vulnerability Atlas, SAEON aims to make the research into characterising and understanding global change accessible and usable to policy and decision makers on a local […]

Creating 3D virtual environment for autonomous vehicles

The Sanborn Map Company set out to demonstrate the accuracy of high definition maps in the context of a 3D reality model of the Silicon Valley area. It generated the 3D reality mesh from aerial oblique imagery of the target area. The company then overlaid the 3D mesh with HD map data that includes a […]

Sugar cane monitoring and analysis using remote sensing

There is a need for more reliable and useful information that can aid farmers and various interested and affected stakeholders in optimising their operations. This study employed remote sensing and GIS techniques to monitor sugar cane crop performance and harvesting on the east coast of South Africa. The South African agricultural industry makes a significant […]
