✨ Update to Planet Basemaps ✨

Planet implemented an improved normalization approach for surface reflectance basemaps that use Sentinel-2 as a normalization target.Why is this important?PlanetScope imagery is collected using a constellation of different satellites—including different satellite generations—that have different relative spectral responses (RSRs). The different RSRs are due to the different sensors, and the variability in PS surface reflectance (SR) data. SR correction for PS data relies on MODIS estimates of the atmospheric optical thickness, which is collected at a different time of day and at a coarser spatial resolution when compared with PS imagery. This leads to significant variability in PS SR data even for images that have the same RSR. For example, same satellite generation and sensor. Therefore, we apply normalization to correct for the variability of SR data leading to more consistent time series.What did we change?We processed the entire Sentinel-2 imagery catalog between 2017 and 2023 using the Framework for Operational Radiometric Correction for Environmental monitoring (FORCE) method then created monthly-cadence, multi-year composites by estimating the 30th percentile for each pixel location using only cloud-free data. How does this improve the product?Sentinel-2 normalized basemaps will have better correlation to FORCE making them more consistent and accurate for time series use.  The improvements were intentionally made to be fully backwards compatible with our current normalization models so existing customer and archive data is still 100% valid and usable.Are there any possible impacts?The new approach works best when there are a high number of observations to build the model. In areas where observations are limited due to clouds or other conditions, the algorithm may produce inaccurate results that manifest as artifacts in the final product. Examples of this are shown in the technical datasheet. If you notice this or any other artifacts please file a ticket and the customer support team will address the issue. This is not expected to be widespread so there is minimal risk of impact.For additional information, refer to the Surface Reflectance Basemaps Technical Datasheet.

✨ Tasking Dashboard and API Updates ✨

This update will simplify how quality issues are managed and also how quality information is presented in the Tasking Dashboard.In preparation for this change, we will also simplify how we surface quality information in the dashboard.These improvements are part of a broader initiative to make Planet quality processes faster, more accurate, and easier to interact with - more to come in the next months!What's New? New Evaluation field API Tasking DashboardThe Evaluation field replaces the Assessment field, which is deprecated and will not reflect future improvements to our quality processes.Rejecting a capture in the Tasking DashboardIf you disagree with the quality evaluation for an order, the Tasking Dashboard allows you to request an additional review of the capture within two weeks from the capture publication date.The Assessment feature replaces the current manual process and you no longer have to contact your Planet representative.Please provide as much information as possible in your request to expedite the process.The process of the capture review is visible in the dashboard in the capture detail view and in the order history.The Planet team reviews your request and might re-task or re-process the image if our quality commitments are not met. Email notifications will be sent to the order creator once a decision is made. Your Planet representative may also reach out for more information about this issue.

Announcing: Planet SDK for Python 2.0.0 is live!

This is a repost. See the original post: hereA few months ago, we let you know about the first beta release of our new Python SDK and CLI. On behalf of the Developer Relations team here at Planet, I’m so excited to announce that this new toolkit is now live and available to all. This new and improved toolkit took the best parts of the original Planet Python library and added a number of great improvements. If you’ve had the opportunity to use the beta tool, you’ll already be familiar with how much easier it makes working with Planet’s APIs in Python: the 2.0 release of our Python SDK abstracts out all the details of interacting with Planet’s APIs, so you can focus on actually using the data and building workflows. We’ve also built a new Command-Line Interface to enable that same easy interaction with Planet APIs – without using code. If you’re already familiar with Planet’s V1 CLI, the new and improved CLI is similar while also allowing you to work in a more modular fashion, enabling a wider array of workflows. Check out the documentation here to learn more about how it works, and don’t miss the Tips & Tricks section for some nifty examples of how you can use the Planet CLI alongside your favorite geospatial tools like GDAL/OGR, Fiona (fio), Kepler.gl, Placemark.io, and more. Both the SDK and the CLI support the Orders, Data, and Subscriptions APIs. To get started, install it from pip with ‘pip install planet’, explore the CLI, and then dive into the Python Guide. Be sure to not miss the SDK Examples that link to a number of Python Notebooks. If you’re already a user of the V1 Python Client, check out our upgrade guide for tips on migrating your code to V2. We’re very interested in hearing from you all as you start using this new toolkit, so don’t hesitate to ask for help or share your feedback with us: just post on Planet Community and tag your post with ‘sdk’ or ‘cli’.

✨Planet Explorer Updates!✨ (April 19, 2023)

Planet Explorer Updates April 19, 2023✨ New ✨It is now easier to preview and order imagery. When you search for imagery, there are three new buttons.Click the X items button to check out each satellite image from that date and make the best choice. Click the eye button to preview the imagery from that date on the map. Click the cart button to add the imagery to your order. You can select and de-select imagery from multiple dates. You can also lock the footprint of an image onto the map to get a better sense of coverage.When you place an order, there is a new option to composite images, which stitches them together. You will receive fewer files and consume less quota. Composite all will give you one file and composite by strip will provide the most consistency (spatial, spectral, environmental, etc). Take a look at the impact of each option on the map to get a sense of what you will receive.You can now more easily use your Hosted Data in other tools and platforms. Download the Cloud Optimized GeoTIFF (COG) and pull it into other web applications at no extra cost.Improvements 🙌🏻You can now select MGRS as a format in Settings, under the Coordinate System section. You can also easily copy MGRS coordinates out of Explorer to paste into other systems. The coordinates can be found in the bottom banner of the app. Please note: precision varies by the zoom level and resolution.

Nonprofit Program

Nonprofit organizations and NGOs are mission-driven, high-impact organizations that aim to promote the common good. However, due to extremely tight budgets, nonprofits often rely on publicly available data that is typically outdated and insufficient at the scale at which they operate.Planet hopes to change some of that dynamic.Organizations have been taking advantage of freely available satellite imagery, such as Landsat and Sentinel, for decades. However, imagery at 30m and 10m respectively often does not provide the detailed spatial information required to monitor change at a local level. In many cases, they need daily imagery so they can take action as change happens in real-time on the ground. Clouds also are commonly an issue with publicly available imagery due to their less frequent temporal resolution. The Planet Nonprofit Program strives to reduce the barriers that nonprofits face by providing a customized offering of its imagery and services. Through tiered product bundling inclusive of steeply discounted pricing on PlanetScope, SkySat, and the Planet cloud-free Basemaps, we hope to enable nonprofits to discover the value of high-temporal, high-resolution imagery to help advance their mission.Planet has worked closely with nonprofit organizations in the past on impactful initiatives, such as detecting illegal mining in the Amazon, preserving cultural heritage in active conflict areas, mapping renewable energy, and measuring global carbon emissions. But to efficiently scale and move faster than the problems we have to solve to ensure a safe, healthy planet for future generations, we need to increase the rate of our ability to get Planet products into the world’s hands. We believe Planet’s Nonprofit Program will help us get closer to that goal.  Are you a nonprofit/NGO that is ready to unlock the power of Planet data? Contact the Nonprofit Program!
