Considerations for selecting a geocoder

Location is at the heart of key business questions. Geocoding – associating each location-based record with accurate geospatial coordinates – is key to the process. This article looks at choosing a geocoder for business. Business operations are more reliant than ever on location intelligence. Location intelligence is the art and science of analysing the connections […]

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 […]

Precise material management in various conditions

Time-of-flight laser technology offers reliable measurements of a variety of materials in a range of visibility conditions on a conveyor belt. This technology can also be used to monitoring conveyor belts for slippage and uneven loading. The Bulkscan LMS511 from SICK Automation uses time-of-flight laser technology to provide non-contact volume flow measurements on conveyor belts. […]

Surveying Africa’s largest uranium mine

Extra tight deadlines, harsh weather conditions and the biggest uranium mine in Africa – these were the project conditions that met Strydom and Associates in the Namib Desert. Using an unmanned aerial vehicle (UAV), the surveyors were able to conduct the needed volumetric measurement over a 15 km2 open pit mine in a single day. […]

Mapping natural woodland burial grounds

To locate individual burial plots with confidence, even when they are covered by trees and plants, as well as plan future burial plot use and manage the site, surveyors were tasked to create an accurate, electronic map of a burial park. Since the 1990s, the concept of woodland burial parks has become increasingly popular. As […]

How lidar is helping clean up the Great Pacific Garbage Patch

The Pacific Ocean is a junk yard for the waste that humans dump from their coastal cities or lose overboard from ships. Its currents push the trash into the middle of the ocean where it remains for years, concentrated into a region called the Great Pacific Garbage Patch. Lidar is playing an important role in […]

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 […]

Learning BIM on the job

We are “BIM-ready” is what I tell myself every morning when I arrive at work. However, the truth of the matter is, we are not BIM ready, we are not even “3D-ready”. So, how do we go about getting there? After months of going back and forth with the directors and staff, we at DSA […]

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 […]

Manned lidar versus drone lidar

Manned lidar has been widely used for roughly twenty years and drone lidar recently has become a new tool in the geo-toolbox. Which should you use? When is it a good time to use drone lidar, or should you continue to use manned lidar? Is drone lidar better? When is drone lidar better? Is drone […]
