EO Browser can browse and compare full-resolution images from all data collections we offer. You simply go to your area of interest, select the desired time frame and cloud coverage, and check the resulting data in your browser. Try out different visualizations or make your own, download high-resolution images and create time-lapse photography.
The Sentinel Center service is providing long-term analysis in an efficient manner. We keep EO Browser, a showcase of our Sentinel Center features free to use, making these features available to just about anyone. Some of the most exciting new EO browser features are collected in our Medium blog posts from March 2020 , July 2020, August 2021 and February 2022 .

The dataset covers: Sentinel-1, Sentinel-2, Sentinel-3, Sentinel-5P, ESA'sarchive of Landsat 5, 7 and 8, global coverage of Landsat 8, Envisat Meris, MODIS, Proba-V and GIBS products.
Explore EO data
EO Browser allows you to instantly visualize satellite data from numerous satellites and data collections. Background processes are responsible for selecting the appropriate scene, downloading and processing data, and mosaic creation. Browsing satellite data has never been easier!
To make it even more exciting, we've prepared the EO Browser's Special Education Mode, where you can explore 12 unique topics, including selected locations of interest and selected visualizations. This EO content is perfect for students and teachers or anyone interested in exploring satellite data.
custom visualization
The satellite imagery in the EO browser can be visualized according to the configuration required by the user. Several visualizations with legends and descriptions have been prepared for you, such as true color, false color, NDVI, EVI, etc.
By choosing Custom , you can choose any combination of bands and simply drag and drop the bands into the RGB channels to make a composition. In the image below, the Danakil Depression has been visualized using Sentinel-2's SWIR, red and blue bands.
Index Tool Quickly create remote sensing indices and control visualizations by dragging and dropping bands into equations.
Our custom scripting feature is a powerful tool for visualizing satellite data. With Javascript, you have full control over visualizations, allowing you to do calculations, logical operators and conditions, data fusion, multi-temporal scripting, and more. For example, you can calculate the snow index, display only the pixels that count as snow in blue, and return all remaining pixels in natural color.
With data fusion, satellite data collections can be combined into a single image, leveraging each image, and taking scripting to the next level. In this example, you can see the Sevastopol region, where the cloudy pixels are returned as Sentinel-1, which penetrates the cloud cover, and the remaining pixels are returned as Sentinel-2 truecolor. Read more about data fusion in our Medium blog post .
Additionally, you can modify the image by editing the intensity of the three color channels (contrast (gain) and brightness (gamma)) in the effects panel .
To create your own visualizations, visit our custom scripts documentation to get started.
Pin and image comparison
EO Browser lets you save pre-fetched locations and visualizations as pins and allows you to share them with others. You can also add descriptions to pins and share them by linking or by exporting a JSON file.
If you want to compare satellite imagery from different dates or areas from different datasets, you can do so by adding a pushpin to the comparison pane and using the split or opacity sliders to compare.
The comparison below shows the amazing Aral sea level drop from 2005 (ENVISAT) to 2019 (Sentinel-2).
Fixed story generator
You can quickly create pin stories of the same area in our pin story generator.
Below, we've created a sample story of the 2018 California wildfires, showing visualizations from different satellites to study the event. It includes gas concentrations from Sentinel-5P, thermal images from Landsat 8, and various visualizations of fire and burning areas from Sentinel-2.
time-lapse photography
The time-lapse feature allows you to create GIFs that change over time. For time-lapse photography, go to your area of interest, select your pre-acquired data collection (eg Sentinel-2) and visualization settings (eg NDVI). Then click the "Create Time-lapse Animation " button on the right, where you can select a time range and choose a preset data frequency. The EO browser will find all available scenes in the area and display them as "frames".
You can then preview the time-lapse on the right side of the window. Note that cloud cover conditions apply to the entire scene level (eg 100km x 100km), so there may still be some frames with excessive cloud cover. Just uncheck the exception frame on the left. Also note that the Time Lapse feature only supports 300 images at a time, so if you need a longer time frame, choose for example the monthly data option.
Below you can see an example of a time-lapse of ship traffic in Shanghai, made with a Sentinel-1 custom composite visualization. Over time, you can observe moving ships.

Statistical Analysis
Outline the area and select Statistics Graph (button in the upper right corner). Note that this only works for layers with one output component (e.g. index, single-band product, etc.).
Since clouds obstruct and significantly distort the NDVI (cloud NDVI values are very low) - the growth curve is not as ordered as one would like. Therefore, we added a simple local area cloud detection algorithm based on the Braaten-Cohen-Yang method (which can be replaced with L2A scene classification data or some other algorithm) with much better results. You can also check the value of each point. Statistics can be exported to a .csv file.
Have you ever wondered how many pixels in your area of interest have a specific value? You can now find this information directly in the EO browser by enabling the histogram feature on the right. This is especially useful when doing analysis or creating custom visualizations.
custom configuration
In the EO browser, you can display and browse your own configurations using custom visualization layers that you can create using our Sentinel Central Dashboard . Below you can see our personal configuration with two commercial Pleiades data layers.
Image and data download
Any image you see on the EO browser screen can be downloaded in a variety of file formats. You can quickly download PNG or JPG images, choose if you want to keep your logo, legend or title, and you can download high-resolution images or TIFF data for further analysis, all for free.
3D capabilities
Check out 3D Earth Observation images! Navigate and even fly over terrain with ease, and when you're done exploring, pinning, sharing, or downloading a visualization. The Terrain Viewer has a range of useful tools; using vertical terrain scaling, you can make flatter areas look more dynamic, and even simulate the movement of the sun and its cast shadows at any time of day. Using a variety of tools, it is possible to manipulate the precision and intensity of shadows, and even control the terrain's environment, diffuse and specular light factors. Check out our blog post to see what you can do with it and see some cool examples.
business data
In EO Browser, you can search, order and visualize commercial high-resolution data in one place! You can choose between Planet Scope , Airbus Pleiades , Airbus Points and Maxar Worldview data. They provide global daily data at high spatial resolutions of 0.5 meters (Pleiades and worldview), 1.5 meters (SPOT) and 3 meters (planetary extent). See how easy it is in the demo video below, and check out the PDF tutorial for step-by-step instructions.
