The images gathered by Doves can be accessed online and some of which is available under an open data access policy, provide up-to-date information relevant to climate monitoring, crop yield prediction, urban planning, and disaster response. With acquisition of BlackBridge in July 2015, Planet Labs had 87 Dove and 5 RapidEye satellites launched into orbit. In 2017, Planet launched an additional 88 Dove satellites, and Google sold its subsidiary Terra Bella and its SkySat satellite constellation to Planet Labs. By September 2018 the company had launched nearly 300 satellites, 150 of which are active. In 2020, Planet Labs launched six additional high-resolution SkySats, and 35 Dove satellites.
Welcome to Planet (formerly Planet Labs)
A short stroll from the downtown San Francisco headquarters of Yelp and LinkedIn, Planet operates the largest and least expensive fleet of satellites in history — the first to take pictures of the entire landmass of the globe, once a day, and sell them to the public. The company is part of a fast-growing commercial satellite industry that is democratizing insights once available mainly to people with Top Secret government security clearances. -- Via NBC
Planet Labs and a Planet API
Planet Labs's launch of the PlanetScope DOVEs is organised around the main idea to image Earth every day.
Planet designs, builds and operates ultra-compact, inexpensive cubesats which can be manufactured in bulk.
Over 130 DOVES from PlanetScope have been launched into very similar orbit planes, circling Earth every 90 minutes:
- 12 satellites on 22 June 2016
- 88 satellites on 15 February 2017
- 48 satellites on 14 July 2017
- 4 satellites on 31 October 2017
- 4 satellites on 12 January 2018
- 16 satellites on 29 November 2018
- 3 satellites on 3 December 2018
- 12 satellites on 27 December 2018
- 20 satellites on 1 April 2019
- 12 satellites on 27 November 2019
- 26 satellites on 3 September 2020
- 9 satellites on 28 October 2020
- 48 satellites on 24 January 2021
- 44 satellites on 13 January 2022
(as of May 2023)
SkySat, operated by Planet, is a high resolution constellation of 21 satellites, able to image revisit any location on Earth up to 10x daily (a daily collection capacity of 400 thousand km²/day). SkySat images are approximately 50 centimeters per pixel resolution.
Constellation & Sensor Overview
The SkySat satellite constellation consists of multiple launches of our SkySat-C generation satellites, first launched in 2016.
Each satellite is 3-axis stabilized and agile enough to slew between different targets of interest. Each satellite has four thrusters for orbital control, along with four reaction wheels and three magnetic torquers for attitude control.
All SkySats contain Cassegrain telescopes with a focal length of 3.6m, with three 5.5 megapixel CMOS imaging detectors making up the focal plane.
SkySat Imagery Products
SkySat Products are available for search and download via Planet’s APIs, User Interfaces, and Integrations, in the form of Scene, Collect, and Video products, which are encoded in our platform as a set of Item Types and Asset Types.
A SkySat Scene Product is an individual framed scene within a strip, captured by the satellite in its line-scan of the Earth. SkySat Satellites have three cameras per satellite, which capture three overlapping strips. Each of these strips contain overlapping scenes, not organized to any particular tiling grid system.
SkySat Scene products are approximately 1 x 2.5 square kilometers in size. They are represented in the Planet Platform as the SkySatScene item type.
A SkySat Collect Product is created by composing roughly 60 SkySat Scenes along an imaging strip into an orthorectified segment, approximately 20 x 5.9 square kilometers in size. They are represented in the Planet Platform as the SkySatCollect item type. This product may be easier to handle, if you're looking at larger areas of interest with SkySat imagery. Due to the image rectification process involved in creating this product, Collect is generally recommended over the Scene product when the AOI spans multiple scenes, particularly if a mosaic or composite image of the individual scenes is required. Collect performs necessary rectification steps automatically. This is especially useful for users who don't feel comfortable doing orthorectification manually.

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. GreenBestPractices

- Floating Forests
Help with the Kelp, Join in -- be a Be a Planet Citizen, Planet Scientist -- http://www.floatingforests.org/
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.

NASA Builds Your Own Private Satellite -- With Google Android (2012)
What would you do with your own private satellite? If you haven't decided, you should. PhoneSat -- a project overseen by NASA's Ames Research Center in Silicon Valley -- wants to lower the cost of building space satellites to the point where anyone with space ambitions could launch one. Yes, it's a satellite made from a phone. The not-so-secret ingredient is Google's Android mobile operating system.
PlanetLabs Launches ...
Planet Labs PBC is an American public Earth imaging company based in San Francisco, California. Their goal is to image the entirety of the Earth daily to monitor changes and pinpoint trends. The company designs and manufactures Triple-CubeSat miniature satellites called Doves that are then delivered into orbit as secondary payloads on other rocket launch missions. -- Via Wikipedia
In 2013, a first generation of Planet Labs 'Dove' micro-satellites were launched into space to remotely image and provide Earth Science data available to all (http://www.planetcitizens.org Planet Citizens]...
Planet Labs filed its founding paperwork and officially launched in 2010, before becoming operationally recognized widely with its first products in 2012.
History is being created, new chapters in visionary Earth Science that started with the original NASA mission statement words: “To understand and protect our home planet..."
Here is a nod and a tip of our green hat to those who pushed forward the first generation of Earth Science from space, as they could see the possibilities and need for environmental protection and the knowledge we needed to have in order to manage our home planet as planet citizens.
Steven Schmidt / GreenPolicy360 Siterunner Here are a few words in memory of George E Brown..."My friend, mentor, and colleague", a man who led big science and put in place a foundation of environmental activism in Congress over three decades.
As a high school student, I met George Brown in the mid-1960s and we began to work, purposefully and closely, to make environmental protection a political reality. He changed the direction of my life and was integral to the founding of Earth Day in 1971 as he helped to set in motion my lifetime of environmental activism. George was looking forward to the 21st century, and especially to the challenges of environmental and earth science programs that he led in Congress for decades, until suddenly he passed away in 1999. George was an amazing man, a visionary who was a mover in the U.S. Congress for four decades, beginning in the 1960s when we began our friendship and work together on a political journey. Let me dedicate this GreenPolicy360 page to George E. Brown as both a biography and memorial. George will always be an influencer for me and his work and legacy is key to understanding my generation...
I can see back to the beginning of an Earth Observation "Inventory". I remember meeting, then years of learning, sharing and work alongside a congressman who set in motion and for decades shepherded U.S. earth science research programs. George E. Brown was a special person who brought a physics and engineering background to Congress. George saw what others didn't really understand and when he showed me the original Mission Statement of NASA, I began to understand.
