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.

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 […]

GIS Data

Average sea-surface topography for 2013 as mapped by CryoSat combined with data from the ERS-2, Envisat, GFO, Topex/Poseidon and Jason missions. Red represents higher sea levels (up to 20 mm) while blue represents lower areas (down to –20 mm). CryoSat’s ground-tracks are seen as long ‘strips’. It can be seen that CryoSat reaches higher latitudes compared to previous radar altimeter missions, and can capture a high-degree of mesoscale activity in the Gulf Stream. Source: ESA/CNES/CLS

Download CryoSat-2 Ice and Ocean Data Products

The polar-orbiting CryoSat-2 satellite provides researchers with a ice and ocean data that is helping to understanding the current state of the world’s ice sheets and oceans.   Since its launch in 2010, CryoSat-2 has collected data that provides scientists with an understanding of changes in the thickness of polar sea ice, […]

This Day in GIS: May 7 – Launch of Proba-V Satellite

Proba-V, the miniature satellite was launched on May 7, 2013 from French Guiana.  The “V” in the name stands for vegetation as Proba-V’s role is to capture imagery about the world’s vegetation to be used, for example, for day-by-day tracking of extreme weather, alerting authorities to crop failures, monitoring inland water […]

GIS Data

Acquired on 13 April 2014 at 23:57 GMT (14 April at 01:57 CEST) by Sentinel-1A, this image shows a transect over the northern part of the Antarctica Peninsula. It was acquired in the satellite’s ‘strip map’ mode with a swath width of 80 km and in dual polarisation. The colours indicate how the land, ice and water reflect the radar signal differently.

First Satellite Images from Sentinel-1A

Launched on April 3 and reaching operational altitude on April 11, the first images captured by the European Space Agency’s (ESA) Sentinel-1A satellite have been made public. The first of five satellites planned for the Sentinel group, Sentintel-1A will be tasked with gathering all-weather, day and night radar images.  Imagery […]
