The processing of global archive of L2A is reaching the end.Mylinkdrive mitsubishi
At the moment, data processing goes back to July Stay updated by following our Forum! An example of non-atmospherically corrected data L1C on the left and atmospherically corrected data L2A on the right.
You can access it seamlessly using a Python client. Visit EDC Marketplace to explore or create your own Jupyter Notebooks, data products and applications for yourself and others to use!
The library is already used by two well-known remote sensing web applications - EO Browser and Sentinel Playground - and we are in the process of migrating other applications to the new library too. For more details see our blog post. While machine learning is a field that is already appreciably useful in Earth observation, its limits are being constantly expanded.
In the past few months, we were looking at how we could use semi-supervised learning - a form of learning, where we use labelled as well as unlabelled data - to improve the performance of deep neural networks in classification of satellite imagery. Besides enabling us to achieve high performance with less labelled data, our results lead to an optimistic implication: that we can use labelled data, sourced only from a small, bounded, geographic region, and still perform well in other unseen regions by adding unlabelled samples from those areas.

Therefore, we are proudly presenting the new features, such as the Education mode, which offers 12 devoted themes, multi-temporal scripting, better control of time intervals, improved time-lapse filters, and five other cool adjustments. Dive in! Continue reading. A quick introduction to remote sensing for teachers who would like to use satellite imagery in class is brought to you by Pierre Markuse. Pierre is a freelance remote sensing expert with a special interest in optical remote sensing, and his images are being used by numerous media outlets.
To learn more about the usage of satellite data, how to process and visualize it, and about different resources on how to get started, read his guest blog post. Get inspired by the scripts submitted in the second round of the Contest, presented in our blog postand submit your own script in the next round. We have received 23 beautiful and useful remote sensing scripts that you can explore globally in EO Browser.
The results are published on the official Contest website and the entries are available in our Custom Scripts repository. To simplify the usage of different versions of custom scripts in the processing API and our web applications, EO Browser and Sentinel Playgroundwe have decided to deprecate versions 1 and 2, and keep only the basic version and version 3. All the scripts in the Custom Script repository using deprecated versions were already converted to V3.
For now, you can still use V1 and V2 as before.Jump to navigation. You simply go to your area of interest, select criteria such as time range and cloud coverage, and inspect the resulting data from different sources. Use our EO browser to filter real-time data by location, date and cloud coverage.
On-the-fly processing and visualization make it possible to build new products in a matter of minutes. Make your data available online, across different platforms and clients.
You can choose amongst standard ones, e. Sentinel Hub services are providing long-term analysis in an efficient way. We maintain our showcase tool EO Browser, to make these features available to just about anyone.
Follow 4 simple steps to compare the data:. The process in the background takes care of the selection of appropriate scenes, download and processing of data, as well as mosaic creation. The visual comparison tool makes it possible to observe changes in the land from onward. Go over your area of interest, select a relevant datasource e. You can then preview the time-lapse in the right part of the window.
Note that the cloud coverage condition is applied on the full scene level e. Just uncheck anomalous frames on the left. Note that this works only for layers with one output component e.
Because of the clouds which get in the way and which distort the NDVI significantly cloud NDVI values are low - growth curve is not as orderly as one would have hoped for. Therefore, we have added a simple local area cloud detection algorithm based on the Braaten-Cohen-Yang method this can be replaced with the L2A scene classification data or some other algorithm and the result is much nicer.
You can also check the numerical values of each point. The image can be prepared based on user's desired configuration. By choosing "Custom" it is even possible to choose any combination of bands as well as some basic math operations between pixel values. You can also set different parameters such as atmospheric correctioncontrast gain and luminance gamma.
If you need these data in your own platform, you can either export them as GeoTiffJP2KMZ format or include them using web services.

Step 1: Search for your area of interest.A wildfire with hot spots highlighted on false color backdrop. Some months ago I posted a script on this blog which could be used to visualize wildfires in Sentinel-2 images using the really excellent Sentinel Hub EO Browser since you are somehow reading this article I suspect you know the EO Browser already, but if not, read about it here and try it outit is free for non-commercial use!
In the past months I saw it used by quite a few people and was even more amazed that people contacted me asking questions about it or giving general feedback. Highlighted wildfire burn scars on a darkened natural color backdrop. So I decided to write a second version of the script, taking in some of the ideas and feedback. The result is the script you can find here, which is quite a bit longer and more complex than the first one, and will hopefully give you even better results. It can still do everything the first script could do, but I improved the visualization of the hot spots, which are looking a bit smoother now, as well as the preset band combinations.Supervised Classification of Sentinel-2 Images
It also allows for a lot more fine-tuning of the resulting image and is a lot more flexible in general. I put more attention on burn scars this time, so some of the new band combinations are meant to especially highlight those. As an added feature, I included a function to automatically highlight burn scars in images, which is especially interesting if you want to visualize the extent of burn scars in a natural color image, or if you are using this highlighted burn scars with a black backdrop as a modifying layer in your GIS application to create a map.
As with most automatic classifications, the results are not always perfect. They vary between really good and totally unusable, it really depends on the scene, the type of vegetation burning and the atmospheric conditions. If you are trying to automatically highlight the burn scars near a still ongoing fire for example, the smoke can be a problem.
That all being said, the script allows a lot of different settings, and with a little manual fine-tuning you can usually generate quite appealing images in a very short time, one of the really great advantages of the EO Browser.
Change a setting, and more or less immediately see the result. Copy and paste the script or right-click and download it here. You can also find it — and other custom scripts — in this custom script repository.
The part of the script you will be using most are the settings used in the variables, here is a very brief explanation of what those variables will do and how you can use them to alter the resulting image. You might also have noticed that I commented out most band combinations. In order to get a quicker processing in the EO Browser you should only have the combinations active you are using for the image you are processing, it will save their resources and your time.
Choose one of the atmospheric correction methods when not working with L2A scenes to get better results. EO Browser screenshot. I divided the hot spots which usually align quite well with active fires and zones with lots of residual heat into three zones. The inner part of the hot spot is fire3followed by fire2 and then fire1 at the edge of the hot spot. Those three variables define the way the script will visualize hot spots.
Usually you can go with the default as shown here, this way the hot spots will appear in red at the edge, followed by orange, and then yellow at the center, creating a more or less natural, fire-like appearance.
This block of variables defines the overall visualization used.
While the first version of the script just had one static background you can now define two different layers and blend them. The layer1Amount and layer2Amount variables define the visibility of the layer.
This can also be used to lighten up a dark image by setting the amount to a value over or to subtract one visualization from the other by setting one of them to a negative value. In the script you will find some predefined band combinations, but instead of using one of those you can also define your own e.The sandbox 2
For the NBR8A12 and NDVI you can also define thresholds and whether they will be shown as discrete colors or as color gradient, color order, and palette used. To change those things you have to edit these lines here:. The first three values after the index are the thresholds used.
The medium threshold is only used with gradients, with discrete colors everything equal or less than the low threshold will be colored as the low value color e. NBR and dNBR can be used to quickly estimate burn severity, however, their values can depend on the scene and type of vegetation.
To conclusively determine burn severity, field assessments will be necessary. With the stretchMin and stretchMax variables you can adjust the lightness of the resulting image, play around to get a nice result. Saturation can be used to make the resulting image more vivid or, if set to 0, to get a monochrome version of your used band combination.This repository contains a collection of custom scripts for Sentinel Hubwhich can be fed to the services via the URL.
The Sentinel-1 imagery is provided by two polar-orbiting satellites, operating day and night performing C-band synthetic aperture radar imaging, enabling them to acquire imagery regardless of the weather. The spatial resolution depends on the mode: approx. See Copernicus services for more details. Dedicated to supplying data for Copernicus servicesSentinel-2 carries a multispectral imager with a swath of km.
The imager provides a versatile set of 13 spectral bands spanning from the visible and near infrared to the shortwave infrared, featuring four spectral bands at 10 m, six bands at 20 m and three bands at 60 m spatial resolution. As indices primarily deal with combining various band reflectances, the table of 13 bands is given here for reference see here for details.
The main objective of the mission is to measure sea surface topography, sea and land surface temperature, and ocean and land surface color with high accuracy and reliability to support ocean forecasting systems, environmental monitoring and climate monitoring. The Sentinel-3 provides imagery in m spatial resolution. Sentinel-5P provides atmospheric measurements, relating to air quality, climate forcing, ozone and UV radiation with high spatio-temporal resolution. EO Browser serves level 2 geophysical products.
Its spatial resolution is below 8km for wavelengths above nm and below 50km for wavelength below nm. The Landsat program is the longest running enterprise for acquisition of satellite imagery of Earth, running from The most recent, Landsat 8was launched on February 11, Landsat-8 data has 11 spectral bands with spatial resolutions ranging from 15 to 60 meters. Landsat 5 long outlived its original three-year design life.
Developed by NASA and launched inLandsat 5 has orbited the planet overtimes while transmitting over 2. The Landsat 7 satellite still orbits the the Earth in a sun-synchronous, near-polar orbit, at an altitude of km mi. The satellites are multispectra, providing visible, near infrared, mid infrared and thermal bands. For more on Landsat 5, including its available bands, read here and for Landsat 7, read here.
PlanetScope satellite constellation consists of more than small satellites called Doves. PlanetScope data complements Sentinel-2 with better spatial resolution 3m and almost global daily coverage. It is an excellent source for vegetation monitoring. For more information on PlanetScope, visit our documentation page. The satellites deliver the incredible global 0.
