This Copernicus Sentinel-2 image features an area in the Santa Cruz Department of Bolivia, where part of the tropical dry forest has been cleared for agricultural use.
Since the 1980s, the area has been rapidly deforested owing to a large agricultural development effort where people from the Andean high plains (the Altiplano region) have been relocated to the lowlands of Bolivia.
The relatively flat lowlands and abundant rainfall make this region suitable for farming. In fact, the local climate allows farmers to benefit from two growing seasons. The region has been transformed from dense forest into a patterned expanse of agricultural land. This deforestation method, common in this part of Bolivia, is characterised by the radial patterns that can be seen clearly in the image.
Each patterned field is approximately 20 sq km and each side is around 2.5 km long.
Small settlements can be seen in the centre of each individual field in the image, which typically contain a church, a school and a soccer field. These communities are joined by a road network depicted by the straight lines that bisect the radial fields and connect the adjacent areas.
Meandering streams and rivers can be seen flowing through the fields. The long, thin strips of land in the top right of the image are most likely cultivated soybean fields.
Rainforests worldwide are being destroyed at an alarming rate. This is of great concern as they play an important role in global climate, and are home to a wide variety of plants and animals.
Because of their unique perspective from space, Earth observation satellites are instrumental in providing comprehensive information on the full extent and rate of deforestation, which is particularly useful for monitoring remote areas.
This composite image was created by combing three separate ‘Normalised Difference Vegetation Index’ images from the Copernicus Sentinel-2 mission. The first image, from 8 April 2019, is visible in red; the second from 22 June 2019, can be seen in green; and the third from 5 September 2019 can be seen in blue. The Normalised Difference Vegetation Index is widely used in remote sensing as it gives scientists an accurate measure of healthy and status of plant growth.
This image is also featured on the Earth from Space video programme.

The Philippines’ Taal volcano erupted on 12 January 2020 – spewing an ash plume approximately 15 km high and forcing large-scale evacuations in the nearby area.
This almost cloud-free image was captured today 23 January at 02:20 UTC (10:20 local time) by the Copernicus Sentinel-2 mission, and shows the island, in the centre of the image, completely covered in a thick layer of ash.
This optical image has also been processed using the mission’s short-wave infrared band to show the ongoing activity in the crater, visible in bright red. Ash blown by strong winds can be seen in Agoncillo, visible southwest of the Taal volcano. Ash has also recorded in other areas of the Batangas province, as well as Manila and Quezon.
According to The Philippine Institute of Volcanology and Seismology bulletin published today, sulphur dioxide emissions were measured at an average of around 140 tonnes. The Taal volcano still remains on alert level four, meaning an explosive eruption is possible in the coming hours or days. The highest alert level is five which indicates an eruption is taking place.
According to the National Disaster Risk Reduction and Management Council, over 50 000 people have been affected so far. In response to the eruption, the Copernicus Emergency Mapping Service was activated. The service uses satellite observations to help civil protection authorities and, in cases of disaster, the international humanitarian community, respond to emergencies.

Many promising geomatics applications benefit from the European navigation programmes Galileo and EGNOS. Land, marine and mine surveying, infrastructure monitoring and mapping and GIS applications that require high precision GNSS are all enabled by both the EU satellite navigation systems. The European GNSS Agency (GSA), together with Geospatial Media, invites you to participate in a free webinar - EGNSS for Geomatics – where you can learn about everything that EGNSS has to offer for geomatics.
GNSS is one of the key Geomatics technologies along with GIS, Earth Observation and Remote Sensing, to help with the geospatial data acquisition. Geomatics disciplines include the geo-data collection means and techniques used in land surveying (including cadastral, construction, mapping and GIS, mining or infrastructure monitoring), photogrammetry, remote sensing, marine surveying and other emerging tools such as drones or mobile mapping, for which high-precision GNSS is either paramount, or a key enabler. EGNOS and Galileo are the two EU satellite navigation systems that provide high-quality positioning, navigation and timing services to users across the whole world.
In the webinar EGNSS for Geomatics experts in navigation and geomatics will guide you through the Galileo and EGNOS programmes, the use, the benefits, the added value for the geomatics user community, and the applications already available as well as the innovation potential.

The Galileo Return Link Service, which allows people in distress to receive automatic acknowledgement that their signal has been received, was declared operational at the 12th European Space Conference, in the Egmont Palace in Brussels on January 21.
The Galileo Return Link Service (RLS) is a free-of-charge global service available to Cospas-Sarsat RLS compatible beacons. The new functionality, currently offered uniquely by Galileo, enables a communication link that relays Return Link Messages (RLM) back to the originating beacon through the Galileo Navigation Signal in Space (I/NAV E1).
The RLS is a joint effort between Cospas-Sarsat and the Galileo programme, supported on one hand by the existing Cospas-Sarsat system and, on the other, by a new Galileo Service Facility called the Return Link Service Provider (RLSP). The RLSP is in charge of securely providing the ground segment interface between the French Mission Control Centre and the Galileo core infrastructure, enabling the transmission of RLM requests to Galileo satellites in view of the beacon.
“The GSA, as the Galileo Search and Rescue Service Authority, has contributed tremendously to the development of the Return Link,” said GSA Executive Director Carlo des Dorides. “The GSA has also supported the development of Galileo Return Link-enabled beacons in recent years. Today, there are several beacon manufacturers worldwide ready to sell Galileo SAR Return Link-compatible beacons, including 5 in Europe,” he said.

By sending a confirmation to the user that the distress signal from the beacon has been localised by the Cospas-Sarsat system and the information relayed to the relevant Search and Rescue governmental authorities, the Return Link Service (RLS) will help save more lives. Receiving reassurance that their distress alert has been well received will deliver a valuable psychological lift to victims and further boost survival rates by reducing panic.
“The contributions to Cospas-Sarsat from France and the CNES, as the Galileo SAR Operator, have been of paramount importance in transforming the Galileo SAR Return Link Service into a success,” said French Space Agency (CNES) President and GSA Administrative Board Chair Jean-Yves Le Gall.
The end-to-end RLM delivery time is expected to be about 10 minutes, but in some cases it may take longer, possibly up to 30 minutes from the moment the beacon is activated until the notification is sent via the Galileo Signal in Space. A total of 15 minutes are allocated to the Cospas-Sarsat system for the localisation and routing of the alert and 15 minutes to the Galileo System for the Return Link message broadcast. However, measured results generally achieve a much faster message delivery time.
And this: Operation Shark Bait: Galileo SAR will save lives!
“Today with its unique differentiator, Galileo SAR is demonstrating how Europe is at the forefront of high technology for the good of European citizens. This wouldn’t have been possible without the strong support of the international community - Cospas-Sarsat, CNES, the International Maritime Organization and the International Civil Aviation Organization - and the main beacon manufacturers, all of which have contributed to the provision of an end-to-end solution for people in distress,” said Thierry Breton, European Commissioner for the Internal Market.
A Return Link capability was first introduced by the Galileo Programme back in 2005. The SAR community soon expressed interest and, in 2008, the Return Link Service was adopted in the Cospas-Sarsat Strategic Plan. Following a great deal of effort by the Galileo Programme, Cospas-Sarsat and beacon manufacturers, a dedicated transmission protocol for Return Link-enabled beacons was established in 2010 and successfully verified during the Galileo In-Orbit Validation Phase in 2013. In 2019, deployment of the required infrastructure was completed and the Return Link Service underwent a thorough System and Service validation that concluded in November 2019.
The SAR Service Definition Document (SAR SDD), available in the European GNSS Service Centre electronic library, is aimed at Galileo SAR users, and describes in detail the characteristics and performance of the Galileo SAR Services. The document presents the relevant system infrastructure and introduces the Minimum Performance Levels that represent Galileo’s commitment to its users during the Galileo SAR Service provision phase.

The SAR community soon expressed interest and, in 2008, the Return Link Service was adopted in the Cospas-Sarsat Strategic Plan. Following a great deal of effort by the Galileo Programme, Cospas-Sarsat and beacon manufacturers, a dedicated transmission protocol for Return Link-enabled beacons was established in 2010 and successfully verified during the Galileo In-Orbit Validation Phase in 2013. In 2019, deployment of the required infrastructure was completed and the Return Link Service underwent a thorough System and Service validation that concluded in November 2019.
The SAR Service Definition Document (SAR SDD), available in the European GNSS Service Centre electronic library, is aimed at Galileo SAR users, and describes in detail the characteristics and performance of the Galileo SAR Services. The document presents the relevant system infrastructure and introduces the Minimum Performance Levels that represent Galileo’s commitment to its users during the Galileo SAR Service provision phase.
