Geospatial-based climate adaptation guide

The Council for Scientific and Industrial Research (CSIR) has released the Green Book in March 2019, an online climate risk profiling and adaptation tool based on peer-reviewed climate models. It offers policy makers a guide to adapt and implement climate change actions. The tool takes a multi-sector approach and has a strong geospatial planning component […]

Spectrum is crucial for space-based earth observation

Climate change and growing exploitation of the earth’s natural resources is leading to a range of environmental problems that require international action. If humanity is going to respond effectively, many of the solutions will be informed by global monitoring of the environment, including the use of space assets. Indeed, space sensing observation is essential to […]

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 […]
