How to Measure Heights From Space?

Accurately measuring the height of buildings, mountains or water bodies is possible from space. Active satellite sensors send out pulses of energy towards the Earth, and measure the strength and origin of the energy received back enabling them to determine … Continue reading

Ocean Colour Cubes

It’s an exciting time to be in ocean colour! A couple of weeks ago we highlighted the new US partnership using ocean colour as an early warning system for harmful freshwater algae blooms, and last week a new ocean colour … Continue reading

Collaborative Earth Observation

Establishing Earth observation systems are large and expensive projects with the combination of satellite development and launch alongside the ground based infrastructure, but the direct Earth observation community itself is fairly small. Working collaboratively and in partnerships can therefore help … Continue reading

Goodbye HICO, Hello PACE – Ocean Colour’s Satellite Symmetry

Ocean colour is the acorn from which Pixalytics eventually grew, and so we were delighted to see last week’s NASA announcement that one of their next generation ocean colour satellites is now more secure with a scheduled launched for 2022. … Continue reading

Did you know remote sensing goes extra-terrestrial?

If you didn’t realise remote sensing of other planets and space objects occurs, you’re not alone. Remote sensing is playing an important role in helping us understand how our planet, and our universe, was created; however this isn’t celebrated much … Continue reading

Twinkle, Twinkle, Little SAR

Last week ESA released a new synthetic aperture radar (SAR) dataset from NASA’s Seasat mission; nothing unusual in that you might think, except that this data is over 36 years old. As part of its Long Term Data Preservation Programme, … Continue reading

The Small and Mighty Proba Missions

This week the European Space Agency announced the latest mission in the Project for OnBoard Automony (PROBA) mini-satellite programme. Proba-3 is planned to launch in four years; and will be a pair of satellites flying in close formation, 150m apart, … Continue reading

Science won’t be rushed!

Last week scientists presented the most accurate model of ocean currents created to date using data from the GOCE satellite; twelve months after the satellite burnt up on re-entry to the Earth’s atmosphere. Immediacy is the standard bearer for the … Continue reading

Smashing the Earth Observation Data Silos

Earth observation (EO) is an all-encompassing term for monitoring our world, however as soon as you start examining the topography of the field in detail you’ll find all sorts of mountains, valleys and oceans. An illustration of the different stands … 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
