Earth Observation

Computer vision is everywhere! But teaching an algorithm to identify objects requires a lot of data and this is definitely the case when we think about GeoAI   But it is not enough to have a lot of data we also need data that is labeled If we are loo...

How do we get data from a satellite down to Earth? How do we task a satellite?  Today the answer is likely to be via radios and a system of downlink sites or ground stations. As the satellites pass overhead or within “line of sight” data can be sent ...

Computer vision is a field of artificial intelligence (AI) that enables computers and systems to derive meaningful information from digital images.    You might think that this is exactly what we are doing in earth observation but there are a few imp...

When comparing multispectral and hyperspectral data it is not simply a case of “more data more better”!  With hyperspectral you have “The curse of Dimensionality” but you also get more flexibility to pick exactly what bands you want to use! With mult...

So you might be wondering why the United Nations World Food Programme needs a geospatial support unit. Let me give you a brief overview,    Basically, they curate and maintain global datasets that they use to model the risk of sudden-onset disasters ...

Personally, I don't feel like aerial imagery gets the attention it deserves! So I invited Michael Bewley - Senior Director of AI Systems at Nearmap back on the podcast to help bring us up to speed on the state of the art of capturing, processing, and...

Tropical forests are large sources of Greenhouse Gas (GHG) emissions, due to deforestation. They could instead be a big part of the climate solution.  Through Norway’s International Climate & Forests Initiative (NICFI), users can now access high-reso...

For some time, there was hype around AI and data science and that they would solve all of our problems. If you think AI solves every problem, then you’re overestimating its utility and where we’re at. However, on the other side, if you’re a business of a...

Applications of thermal imaging from space include monitoring wildfires, urban heat islands, economic activity, and the built environment.  But it's not easy ;)    Connect with Robin Cole at https://robmarkcole.com/   Check out the Earth Observation Hub!...

It turns out that monitoring atmospheric pollution from space is really hard! But if you can do it will help you understand air quality, solar energy, ozone Layer and UV radiation, emissions and surfaces fluxes, and climate forcing    Contact Mark on Twi...
