3D laser scanning workflow overview for newbies

This article looks at  point cloud basics and a workflow which will enable capturing and processing of a 3D laser scan. Laser scanners collect surface data about an object or structure by beaming a laser repeatedly off its surface and plotting points (equivalent to each beam that is emitted) into what is known as a […]

Insights and long-term value of the Notre-Dame Cathedral 3D project

In 2011, the late Prof. Andrew Tallon used 3D laser scanning to map the Notre-Dame Cathedral. On 15 April 2019 the conflagration of the cathedral’s spire highlight the cultural and historical value of a geospatial technologies such as 3D laser scanning, far beyond its initial value of understanding the construction of Gothic architecture. The advent […]

Six considerations for choosing a machine control receiver

Looking for a GPS receiver for moving earth, mining or construction? Here are important things to bear in mind. GPS receivers can either assist operators in making better decisions by providing precise position information (indicate-only mode) or the GPS receiver, as part of a guidance system, can take over the operation of the machine’s implement […]

Implementing a successful enterprise GIS

This article will detail a twelve-step plan to implement an enterprise GIS system, the key components to a successful implementation. It is based on the two-and-a-half-year process that Sasol Mining has undergone to digitise their spatial information, making the data more accessible to the general Sasol employee. GIS is commonly thought of as a simple […]

Implementing an enhanced deformation monitoring system

The Sri Lankan Authorities recognised that the ongoing monitoring of Victoria Dam is essential in understanding the structural integrity of the dam post construction, as well as to understand how it is behaving in accordance with its original design. It was deemed important to update the monitoring system to capitalise on the latest advances in […]
