Temporal: The forgotten resolution
Temporal resolution shouldn’t be forgotten when considering satellite imagery; however it’s often neglected, with its partners of spatial and spectral resolution getting the limelight. The reason is the special relationship spatial and spectral has, where a higher spectral resolution has … Continue reading
SMAP ready to map!
On the 31st January NASA launched their Soil Moisture Active Passive satellite, generally known by the more pronounceable acronym SMAP, aboard the Delta 2 rocket. It will go into a near polar sun-synchronous orbit at an altitude of 685km. The … Continue reading
The Satellite Earth Observation Industry Began …
The satellite Earth observation (EO) industry, arguably, began 37 years ago yesterday. Now, before everyone starts tweeting and emailing hear me out. Although by this date EO satellites were in orbit, data successfully collected and imagery produced, the concept of … Continue reading

What do colours mean in satellite imagery?
Satellite images are a kaleidoscope of colours, all vying for attention. It’s important to be clear what the colours are showing, and more importantly, what they may not be showing, to interpret the image correctly. For example, a patch of … Continue reading
Current Work in Remote Sensing and Photogrammetry
Last week the annual Remote Sensing and Photogrammetry Society (RSPSoc) conference was held in Aberystwyth. Now I’ve stepped down as RSPSoc Chairman I could relax and enjoy this year’s event as a delegate. Arriving on Wednesday morning, the first session … Continue reading
Rosetta: Extra-terrestrial Observation
Most people will have seen last week’s news about ESA’s Rosetta spacecraft arriving at comet 67P/Churyumov-Gerasimenko and the animated images of the ‘rubber-duck’ shaped object taken from Navigation Camera (NavCam), part of Rosetta’s Attitude and Orbital Control System. The arrival … Continue reading
Looking Deeper At Phytoplankton from Space
NASA is currently in the middle of a joint airborne and sea campaign to study the ocean and atmosphere in preparation for developing instruments for future spaceborne missions. The Ship-Aircraft Bio-Optical Research (SABOR) campaign has brought together experts from a … Continue reading
How Many Earth Observation Satellites are in Space?
Space is growing market! With Google recently announcing its purchase of Skybox Imaging, the myriad of organisations jostling to be the first to offer commercial space flights and the launch of two UK satellites last week(TechDemoSat-1 and UKube-1) it’s clear … Continue reading
