- #NewSpace - Planet Labs has raised more than $160 million and launched 73 global imaging satellites... Three years ago co-founder Will Marshall built the first of the miniature satellites nicknamed “doves” in a Silicon Valley garage.
- “A lot of people were very skeptical, and what we were trying to do seemed ludicrous,” says Marshall, a former engineer at NASA Ames Research Center in Mountain View, California. “But we have assets in orbit, and customers who are very interested in the data. Every time we take a picture, we can see how the world is changing.”

The Reefscape project aims to improve our understanding of the condition of coral reefs worldwide, while simultaneously developing spectral libraries needed to advance the development of a new satellite mission.
To gather a more comprehensive understanding of the condition of global reef ecosystems, we need a way to assess and monitor them on a large geographic scale. New satellites, such as those from Planet (formerly Planet Labs), are, as of 2017, able to capture near-daily imagery of coral reefs worldwide. Planet’s high-resolution imagery of reef location provides us with an at-your-fingertips understanding of the extent of shallow, horizontally oriented reefs.
To lay the groundwork for a new satellite mission, it is important to develop a baseline understanding of current reef extent, and to pair that information with field-based assessments of reef condition. In addition, improved spectral libraries of corals are required to drive the new satellite design and approach for global monitoring.

 Google Earth Outreach
Under the forward-looking initiative and leadership of Planet Citizen and Bioneers Rebecca Moore who set in motion Google Earth Outreach, Google Earth Engine is an online environment monitoring platform that makes available to the entire world a dynamic digital model of our planet that is updated daily.
The Google Earth Outreach Engine stores petabytes of satellite data and allows high-performance tools to analyze and interpret this information that can then be visualized on a map...

Kyle Cavanaugh had an idea. “These forests change so rapidly and on a variety of different time scales—months to years to decades—so we needed a long record with consistent, repeated observations,” Cavanaugh said. He devised a method to use Landsat satellite data to monitor kelp forests.
A few things made Landsat an obvious resource. Since the 1970s, the satellites have had a regular collection schedule (twice monthly). Their data and images are managed by the U.S. Geological Survey and are reliably stored in an archive that dates back more than forty years. And Landsat’s images are calibrated, or standardized, across different generations of satellites, making it possible to compare data collected across several decades...
Landsat measures the energy reflected and emitted from Earth at many different wavelengths. By knowing how features on Earth reflect or absorb energy at certain wavelengths, scientists can map and measure changes to the surface. The most important feature for the kelp researchers is Landsat’s near-infrared band, which measures wavelengths of light that are just outside our visual range. Healthy vegetation strongly reflects near-infrared energy, so this band is often used in plant studies. Also, water absorbs a lot of near-infrared energy and reflects little, making the band particularly good for mapping boundaries between land and water.
“The near-infrared is key for identifying kelp from surrounding water,” Cavanaugh explained. “Like other types of photosynthesizing vegetation, giant kelp have high reflectance in the near infrared. This makes the kelp canopy really stand out from the surrounding water.”
After a recent meeting on kelp forests and climate change, researchers Byrnes, Cavanaugh, and other colleagues set out to consolidate all of the available kelp forest data from around the world. They wanted to take a step toward understanding how climate change is affecting kelp globally, but they quickly discovered they had a sparse patchwork of information.
Byrnes was struck with a thought. They had used Landsat to expand their studies across time, so why not use Landsat to expand their studies around the world? Could Landsat be used to establish global trends in kelp forest extent? The answer was yes, but the problem was eyeballs.
Unlike research on terrestrial vegetation—which uses Landsat data and powerful computer processing arrays to make worldwide calculations—distinguishing kelp forests requires manual interpretation. While kelp forests pop out to the human eye in near-infrared imagery, computers looking at the data numerically can confuse kelp patches with land vegetation. Programs and coded logic that separate aquatic vegetation from land vegetation can be confounded by things like clouds, sunglint, and sea foam...
"Automated classification methods just don’t produce acceptable levels of accuracy..."
Byrnes and Cavanaugh put together a science team and joined with Zooniverse, a group that connects professional scientists with citizen scientists in order to help analyze large amounts of data. The result was the Floating Forests project.
The Floating Forest concept is all about getting more eyeballs on Landsat imagery. Citizen scientists—recruited via the Internet—are instructed in how to hunt for giant kelp in satellite imagery. They are then given Landsat images and asked to outline any giant kelp patches that they find. Their findings are crosschecked with those from other citizen scientists and then passed to the science team for verification. The size and location of these forests are catalogued and used to study global kelp trends.
