Aravind Ravichandran is the founder of TerraWatch Space, where he does consulting and strategy with the goal, in his words, to demystify Earth Observation. This is an introduction to the 5 layers Aravind identifies as making the Earth Observation industry. Aravind writes one of the most popular newsletter gathering the latest news and featuring deep dives analysing the industry. We also hosts a podcast -albeit on pause at the moment- so was the perfect person to discuss Earth Observation at a high level.Episode Sponsor: SkyFiGet high resolution imagery easily, with prices up front on SkyFi.comAbout AravindTwitterLinkedInTerraWatch spaceAravind's NewsletterAravind's podcastShownotesNote: Links to books are Amazon Affiliate links.
