Last Week in Earth Observation: June 5, 2023

Hyperspectral EO, climate risk, EO technology hype cycle, edge computing and how much is too much when it comes to flying.

Welcome to a new edition of ‘Last Week in Earth Observation, containing a summary of major developments in EO from last week and some thoughts on the sector that I have come to love.

In this edition: hyperspectral EO, climate risk, EO technology hype cycle, edge computing and how much is too much when it comes to flying.

5. SAR wave vs hyperspectral wave in EO

We have seen quite a few investments into SAR and hyperspectral companies in the past couple of years and it seems to be continuing in 2023. Next week, I will include a summary of investments in EO for 2022, by sensor and by vertical - so you can see that for yourself. But, as I noted my very own EO technology hype cycle, SAR and hyperspectral are at the peak of inflated expectations.

But one key difference between the ongoing SAR wave and hyperspectral wave in Earth observation: The distinct foundations that have been built over the years, for data processing and use case demonstration of the value derived from each sensor.

The bottom line? SAR EO companies somewhat have it easy, as the foundation have been there - basic tools were available and some use cases were already demonstrated. Hyperspectral EO companies have some work to do - the onus is on them to both build the tools and demonstrate the value add for end-users.

One visual leveraging EO


This is a new section where I want to link an image or a video based on EO that is interesting or cool or informative (or all of the above), that caught my attention.

6. How much are we flying?

For this week, I found this interesting image from FlightRadar24, a Swedish company that provides real-time aircraft flight tracking information, leveraging data from navigation satellites, automatic dependent surveillance-broadcast (ADS-B) sensors and other sources.

The following image, posted on Twitter on May 26, shows 22,000 flights in the air at the same time, which the company claims is the most number of flights they have ever tracked at a single point in time. FlightRadar24 also claims that they tracked 253,000 flights on air on May 25 - another record. Just how much is too much flying?1

7. Why Space Sustainability Matters for Earth Observation

We are launching more Earth observation satellites than ever before, and the progress in space tech has meant that any individual, organisation or country can put up an instrument in space to collect data for scientific, commercial, environmental or strategic purposes. But how sustainable is that?

To discuss this, I had Krystal Azelton, Director of Application Programs at the Secure World Foundation to discuss: the state of the space environment, the threats and worst-case scenarios, what regulations exist and how effective they are, the similarities with climate policies, why every stakeholder in the Earth observation sector should care about this topic and more.


Until next time,

Aravind.
