One of the United Nations Sustainable Development Goals is SDG 11: “Make cities and human settlements inclusive, safe, resilient and sustainable”. Earth Observation (EO) data provides the data about cities that forms the basis for the solutions needed to meet this ambitious goal. According to the European Commission, a smart city is “a place where […]Read More
SAR remote sensing methods have evolved to be among the most useful monitoring techniques in modern mining. This article describes some of the newest technologies for keeping mines safe for both mining operators as well as the communities and landscapes they exist in. Mining is an important economic activity providing many of the natural resources […]Read More
On 23 December 2021, Copernicus Sentinel-1B experienced an anomaly related to the instrument electronics power supply provided by the satellite platform, leaving it unable to deliver radar data. Since then spacecraft operators and engineers have been working tirelessly to rectify the issue. Unfortunately, despite all concerted efforts, ESA and the European Commission announce that it […]Read More
Synthetic Aperture Radar (SAR) from space is particularly well suited for change detection on the ground. With its ability to look through clouds and darkness, SAR remote sensing consistently produces high quality, well calibrated imagery with good geolocation accuracy. This article is part of our series on SAR space data applications and our series on […]Read More
Synthetic Aperture Radar (SAR) imaging from space is in its golden age. With an increasing number of space-based SAR sensors in operation, and an increasingly growing temporal and spatial resolution, combined with the characteristics of SAR: independent from daylight, cloud coverage and weather conditions, we are seeing a fast growth of applications. One of the […]Read More
Agriculture is one of the key application areas of satellite data. We have all heard about precision farming using satellite navigation signals and a large array of Earth Observation techniques that help farmers identify soil characteristics and crop health. In this article we describe these techniques in a list of space data ‘indices’ that describe […]Read More
Radar satellite imagery (SAR) offers great opportunities for assisting humanitarian operations during war, offering support to displaced people in their own and in hosting countries, like the current situation in Ukraine. It helps relief organizations to closely follow the number of people in need and their locations, by monitoring the areas affected by the war. […]Read More
One of the biggest challenges of climate change is water-related. Flooding of cities is a natural hazard that occurs in many countries worldwide, generating economic, material and human loss. These floods bring misery to those that live in the areas affected. Water can come into people’s houses, pollute drinking water, break down electricity supply, block […]Read More
The rise in population in the last 100 years has led to a rapid expansion of the world’s cities. As a consequence, there are big infrastructure developments and construction projects, leading to urban change, which requires monitoring. Similarly, natural disasters or war can cause quick changes to a city infrastructure. Remote sensing by imaging radar […]Read More
The interpretation of Synthetic Aperture Radar (SAR) satellite images involves the identification and measurement of targets in a radar image. This radar image is the result of extensive data processing, including calibration, geometric, and radiometric corrections. Analysing SAR images: finding your targets A target may be any feature or object which can be observed in […]Read More
