Satellite images are one of the most important data sources for environmental monitoring and carbon sink assessment. Whether you’re compensating for a flight 🛩 or a burger 🍔, images taken from space are used to evaluate the forestation projects supported by your money. Hundreds of satellites orbiting the earth provide a continuous stream of data for accurate ecological analysis.

We launched the Terramonitor service in 2018 to help scientists and businesses to get access to high quality calibrated satellite images. During the past years we have developed a completely automated satellite image processing chain which acquires the raw data, performs several processing steps and delivers the data in various formats to the user.

Our plan for the next years is to build the first global calibration network for earth observation satellites, with terrestrial calibration sites on all continents. The calibration sites can be used for calibration and quality assurance of all high-resolution satellites, including open-access satellites of the Copernicus program as well as hundreds of commercial satellites. Using calibrated satellite images significantly increases the accuracy of satellite-based analysis related to, for example, climate change, biodiversity loss and carbon sequestration. For satellite operators, quality assurance is essential for producing information to demonstrate their data are fit for use.

Now, in April 2022, we have launched L×4, the world’s first blockchain-based fund dedicated to satellite calibration. The fund consists of thousands of digital collectibles, Landx4 tiles, that represent pieces of satellite images all around the world. By owning a specific Landx4 tile, the owner gets exclusive access to unique calibrated satellite images for the corresponding geographical area. The fund will be implemented using NFT (non-fungible token) technology, which makes it easy for anyone to invest in the fund and support the calibration technology development. Landx4 tile owners can trade tiles like traditional stocks. The main difference is that trading takes place in the blockchain in a decentralized fashion.

Ok, got it. But why should I take part in L×4? Here are the three main reasons:

  1. 🛰 Support satellite calibration technology. Make an impact to improve the accuracy of satellite images used in climate change, biodiversity loss and carbon sequestration research, among other use cases. As a tile owner and community member, you will get the right to vote in decisions about the future directions of the fund.
  2. 🪙 Invest. The L×4 fund provides an easy way for anyone to invest in our technology with little capital. As with any startup investment, there are big risks but even bigger opportunities since the satellite data market is growing rapidly.
  3. 🖌 Art & games. Calibrated satellite images are unique pieces of art, showing the beauty of our planet in an unprecedented fashion. By owning a Landx4 tile you are the licensed owner of the digital asset and can showcase it in a digital art gallery. Games and prizes will be announced for tile owners, related to climate change, biodiversity and carbon sequestration.

Sounds good, when and how can I participate? The fund will be released to the public during Q2/2022. Join us in Discord to get updated!
