Online tool to simplify environmental sensitivity screening

The National Web based Environmental Screening Tool developed by the Department of Environmental Affairs aims is to provide users with readily available spatial datasets to fast track the environmental assessment process by providing timeous reports with less frustration. In November 2015 the Department of Environmental Affairs (DEA) embarked on the development of a “National Web […]

Using satellite imagery and machine learning to protect elephants

African elephants are at risk in the majority of the countries where they live because of poaching. To plan long-term sustainable solutions to the stresses elephants are experiencing, it is necessary to have accurate data on elephant numbers and their geographical range to identify high-risk areas. There are several methods used to conduct elephant surveys, […]

A crash course in AI-driven object detection

Almost every day we hear we can use the superpowers of artificial intelligence (AI) to make work easier, to automate routine tasks, to speed up workflows, increase accuracy and make more money. But what if you are not a machine learning expert? This quick guide outlines the basics of how AI-driven object detection works, and […]

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 […]

Measuring accurate heights across a country

A look at how the National Oceanic and Atmospheric Administration (NOAA) scientists are changing the way heights is measured accurately across the United States. Scientists at NOAA’s National Geodetic Survey (NGS) maintain a nationwide coordinate system that defines latitude, longitude, height, scale, gravity, orientation, and the national shoreline throughout the United States. This reference system […]

Screening tool simplifies environmental authorisation process

The Department of Environmental Affairs’ Environmental Screening tool is a national online GIS-based tool which creates a centralised system for generating environmental sensitivity reports for areas of proposed development. The Department of Environmental Affairs (DEA) is responsible for protecting, conserving and improving the South African environment and its natural resources. As part of its mandate, […]
