EO Browser makes it possible to browse and compare full resolution images from the sources mentioned above. 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.

Search scenes

You can browse images from the entire Earth's surface and make simple queries to restrict scenes to specific date ranges, location and cloud cover.

Browse available data using EO Browser

Use our EO browser to filter real-time data by location, date and cloud coverage.

EO Browser

Hover over the numbers to learn more about each step.

  1. 1STEP 1Specify an area of interest.

  2. 2STEP 2Define the temporal settings (e.g. last available data, last available data without clouds, one month ago, specific time period or any combination).

Configure visualisation

On-the-fly processing and visualization make it possible to build new products in a matter of minutes.

Hover over the numbers to learn more about each step.

  1. 3STEP 3Choose amongst several pre-set visualization options e.g. true colour, false colour, NDVI, EVI, etc.) or define one that suits your needs best.

  2. 4STEP 4Download full resolution image.

Expose the data via WMS

Make your data available online, across different platforms and clients.Try our WMS/WMTS service.

Hover over the numbers to learn more about each step.

  1. 5STEP 5Choose the coordinate projection you would want to use the data in.You can choose amongst standard ones, e.g. EPSG:3857, "Google maps", EPSG:4326, "Google earth", UTM or the national ones - in case your is missing amongst the options, let us know so that we add it.

  2. 7STEP 7Get unique WMS address.

  3. 8STEP 8Include WMS in any 3rd party tool, e.g. QGis, ArcGIS, OpenLayers or other proprietary tools.WMS is based on OGC standards so it should work everywhere.

Comparison of Data

Follow 4 simple steps to compare the data:

Step 1: Search for your area of interest.

Step 2: Select criteria such as time range and cloud coverage.

Step 3: Inspect the resulting data from different sources.

Step 4: Pin your favorite results and compare them.

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 1984 onward.

Time-lapse

Go over your area of interest, select a relevant datasource (e.g. Sentinel-2, Landsat-8, MODIS) and visualization setting (true colour, false colour, NDVI). Then click on the “Create Gif” button where you can choose the time range. EO Browser will find all the available scenes for the area, subject to your cloud coverage requirement, 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.

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.

Different Visualisation

The image can be prepared based on user's desired configuration. There are already several visualizations available such as true color, false color, NDVI, EVI, etc. 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 correction, contrast (gain) and luminance (gamma).

If you need these data in your own platform, you can either export them as GeoTiff, JP2, KMZ format or include them using web services.

User guide:

1. Search

  • Search for the location of your interest either by scrolling the map with mouse or enter location in the search field on the right side of your screen.
  • Choose from which satellites you want to receive the data (checkboxes on the left side of your screen).
  • Select maximum Cloud coverage percentage.
  • Select time range by either typing the date or select the date from calendar.

Additional features:

  • Enable  option to view land cover and vegetation growth (with spacial resolution 300m and 100m).
  • Choose Layer from the dropdown menu (Color or NDVI with 1km or 100m spacial resolution).
  • Select Date by either typing the date or select the date from calendar.
  • Click  button to import KML/KMZ file - to create area of interest. Area will be used for clipping when exporting an image.

* Proba-V is Esa's minisatellite which provides land cover and vegetation growth across the entire planet every two days.
 

2. Results

Next to the thumbnail of your location - image/tile information is shown:

  • Sensing date - 
  • Sensing time - 
  • Cloud Coverage - 
  • Tile Crs - 
  • Mgrs Location - 

Clicking on the  icon you get access to raw data image from EO Cloud or SciHub. Clicking on the  button next to the image thumbnail will open the Visualisation tab.
 

3. Visualization

The user can apply different pre-installed or custom spectral band combinations to visualise images:

  • Custom Script - Select custom band combinations or write your own classification script for visualisation of images.
  • True Color - Visual interpretation of land cover.
  • False Color - Visual interpretation of vegetation.
  • NDVI - Vegetation index.
  • Moisture index
  • SWIR - Shortwave-infrared index.
  • NDWI - Normalized Difference Water Index.

User Configurations - Sentinel Hub users, when logged in, can apply one of their own configurations from Configuration Utility tool to fine-tune the visualization experience and to enable use of advanced functions such as multi-temporal processing, etc.

Using Linked Custom Scripts - Use custom scripts, which are stored elsewhere, either on Google drive, GitHub or in our Custom script repository. Paste the URL of the script into a text box in the advanced script editing panel and click Refresh.

Before downloading, you can now define area of interest (AOI) by clicking on the  icon. Data will be clipped accordingly.
Prepare download – By enabling  toggle button one can choose between various image formats, image resolutions and coordinate systems before downloading the image.
Download Image – Click Download Image button to start downloading image in GeoTiffJP2 or KMZ format. Low-scale exports are possible as well if one wants to download GeoTiff of the whole Europe for example.

Additional features:

  • Zoom to the centre of the tile - By clicking on the  icon.
  • Pin layer for later comparison (your pins will be stored in application for future use) - By clicking on the  icon.
  • Toggle between Hide and Show Layer options - By clicking on the  icon.  
  • Set different parameters such as atmospheric correction, contrast (gain) and luminance (gamma) by clicking Effectsicon.
  • Change the date of the image directly in visualization tab, without going back to results panel. Type in or paste the date of the imagery in addition to selecting it from a calendar.

4. My pins

In this section your favourite(pined) images are listed. Clicking on the Compare button will compare pinned images in 2 modes:

  • Opacity (Draw opacity slider left or right to fade between compared images)
  • Split (Draw split slider left or right to set the boundary between compared images)

The visual comparison tool makes it possible to observe changes in the land from 1984 onward.

Additional features:

  • Zoom to location - 
  • Remove pin -
