EO Browser makes it possible to browse and compare full resolution images from all the data collections we provide. You simply go to your area of interest, select your desired time range and cloud coverage, and inspect the resulting data in the browser. Try out different visualizations or make your own, download high resolution images and create timelapses.

Sentinel Hub services are providing long-term analysis in an efficient way. We keep EO Browser, our showcase of Sentinel Hub functionality free to use, to make 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 and July 2020.

Explore EO Data

EO Browser allows you to visualize satellite data from numerous satellites and data collections instantly. The process in the background takes care of the selection of appropriate scenes, download and processing of data, as well as mosaic creation. Browsing satellite data has never been so easy!

To make it even more exciting, we have prepared a special education mode of EO Browser, where you can explore 12 unique themes, with the selected locations of interest and chosen visualizations. This EO content is perfect for students and teachers or anyone interested to explore satllite data.

Custom Visualization

Satelite imagery in EO Browser can be visualized based on user's desired configuration. There are already several visualizations with legends and descriptions prepared for you, such as true color, false color, NDVI, EVI, etc.

By choosing Custom it is possible to choose any combination of bands and make a composite by simply drag and dropping the bands into the RGB channels. On the image below, Danakil Depression has been visualized using SWIR, RED and BLUE bands of Sentinel-2.

The index tool makes it possible to quickly create remote sensing indices and control the visualization, by drag and dropping bands into the equation.

Our custom script functionality is a powerful tool for visualizing satellite data. Using Javascript, you have full control over your visualization, allowing you to make computations, logical operators and conditions, data fusion, multitemporal scripting, etc. You could for example calculate the snow index and display only the pixels you calculated to be snow as blue, and return all the remaining pixels in natural color.

Data fusion makes it possible to combine satellite data collections in a single image, take advantage of each, and bring your scripting to a new level. In this example, you can see Sevastopol area, with cloudy pixels returned in Sentinel-1, which penetrates clouds, and the rest in Sentinel-2 true color. Read more about data fusion in our Medium blog post.

Additionally, you can modify your image by editing the strength of the three color channels, contrast (gain) and luminance (gamma) in the effects pannel.

To make your own visualizations, visit our custom scripts documentation to get started.

Pins and Image Comparison

EO Browser makes it possible for you to save your preffered locations and visualizations as pins, and allows you to share them with others. You can add descriptions to your pins as well, and share them via link, or via a JSON file by exporting it.

If you would like to compare satellite imagery of an area on different dates or from different data collections, you can do that by adding your pins to the compare pannel, and compare them using split or opacity sliders.

The comparison below displays the striking Aral sea water level reduction from 2005 (ENVISAT) to 2019 (Sentinel-2).

Pin Story Builder

You can quickly create a story of your pins of the same area in our pin story builder.

Below, we have created an example story of the California 2018 wildfires, displaying visualizations from different satellites to study the event. It includes gas concentrations from Sentinel-5P, thermal imagery from Landsat 8 and various visualizations of the fire and burned area from Sentinel-2.

Time-lapse

Time lapse functionality makes it possible for you to create gifs of changes through time. To make a timelapse, go to your area of interest, select your preffered data collection (e.g. Sentinel-2) and visualization setting (e.g. NDVI). Then click on the Create timelapse animation button on the right, where you can choose your time range and select your preffered data frequency. EO Browser will find all the available scenes for the area and present them as “frames”.

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.g. 100km x 100km), so there might still be some frames with too many clouds.  Just uncheck anomalous frames on the left. Note also that timelapse functionality supports only 300 images at once, so if you need a longer time-frame, select for example a monthly data option.

Below you can see the example timelapse of Shanghai ship traffic, made with a Sentinel-1 custom composite visualization. You can observe the moving ships as time passes.

Statistical Analysis

Outline the area and select the statistical info chart (buttons on the top right). Note that this works only for layers with one output component (e.g. indices, single band products, etc.).

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. Statistical information can be exported into a .csv file.

Custom Configurations

In EO Browser, you can display and explore your own configurations with your custom visualization layers, which you can create using our Sentinel Hub 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 various file formats. You can download quick PNG or JPG image, selecting whether you want to keep the logo, legend or captions, you can download high resolution imagery, or TIFF data for further analysis, all for free.
