Spatial Analysis

Changes in Cambodia from Sentinel-1A readings at 20 m resolution, acquired every 12 days from March 2015 to March 2016. Dark blue represents water surfaces, light blue to magenta represents agriculture (bare soil and cultivated fields), light to dark green represents forests, and white indicates settlements. In particular, the varying shades of magenta indicate rice sowing and transplanting between mid-September and the end of October.

Using Remote Sensing to Map Rice Paddy Drop in the Mekong Delta

Satellites including Europe’s Sentinel-1A can now track the rise and fall of different agricultural products around the world. The satellite’s imagery showed that rice production in the Mekong Delta has decreased in the past year.

Acquired on 27 June 2015 at 10:25 UTC (12:25 CEST), just four days after launch, this close-up of France’s southern coast from Nice airport (lower left) to Menton (upper right) is a subset from the first image from the Sentinel-2A satellite. This false colour image was processed including the instrument’s high-resolution infrared spectral channel.Acquired on 27 June 2015 at 10:25 UTC (12:25 CEST), just four days after launch, this close-up of France’s southern coast from Nice airport (lower left) to Menton (upper right) is a subset from the first image from the Sentinel-2A satellite.

First Satellite Images from Sentinel-2 Delivered

Four days after its launch, the first images from Sentinel-2 have been delivered.  Covering an area from central Europe and the Mediterranean, ending in Algeria, images from the satellite is part of the Copernicus environmental monitoring program.  Designed as a twin satellite system, Sentinel-2A and Sentinel-2b (which will launch in 2016) will provide […]

Using 200 million measurements collected by ESA’s CryoSat mission between January 2011 and January 2014, researchers from the Alfred Wegener Institute in Germany have discovered that the Antarctic ice sheet is shrinking in volume by 125 cubic kilometres a year. The study, which was published in a paper published on 20 August 2014 in the European Geosciences Union’s Cryosphere journal, also showed that Greenland is losing about 375 cubic kilometres a yearUsing 200 million measurements collected by ESA’s CryoSat mission between January 2011 and January 2014, researchers from the Alfred Wegener Institute in Germany have discovered that the Antarctic ice sheet is shrinking in volume by 125 cubic kilometres a year.

CryoSat Shows Record Loss of Polar Ice

Scientists concerned about climate change are closely monitoring the thickness of polar sea ice. For many years, ice cover has been deemed a significant gauge of global warming’s impact on the Earth. The loss of sea ice in the Arctic and Antarctica could speed up the rate of global warming, […]

Spatial Analysis

Information on land cover, market values and forest management was used as input to a managed timber production model and applied to the Huong Son forest concession. The left image displays the total net present value (TNPV) of the forecasted timber extraction until 2045 (based on average values); the darker the area, the greater the value. The image on the right image displays the total biomass foreseen to be extracted by the forest operations within each parcel; the darker green the more biomass. Numbers correspond to the parcels listed in the forest management plan of the Huong Son Company. Source: ESA/GeoVille

Evaluating Ecosystems from Space

The impact of humans upon the planet’s ecosystems has long been a concern for scientists, and now the European Space Agency (ESA) is taking their assessment of natural resources to a new level with satellite technology. The emphasis of a new project from the ESA is on promoting sustainability and […]
