Searching remote sensed imagery from various image providers
Searching and browsing remote sensed imagery directly from JupyterLab.
This extension is using the eodag library to efficiently search from various image providers. It can transform search results to code cells into the active Python notebook to further process/visualize the dataset.
The extension is composed of a Python package named
eodag-labextension, and add a tab into the left panel of Jupyter
Lab. The package consist of a Python Jupyter notebook REST service consumed by the client and served at
/user/<username>/eodag/ for JupyterHub (a home page is available at that URL).
- pip >= 21.0
eodag-labextensionversions are compatibles with JupyterLab v3
- v3.1.3 is the latest version compatible with JupyterLab v2
- v2.1.3 is the latest version compatible with JupyterLab v1
pip install eodag-labextension
You can also uninstall it quite simply.
pip uninstall eodag-labextension
eodag configuration file should be localized at
Make sure that that file is configured properly.
You can use
eodag-labextension inside a Jupyter notebook. Start Jupyter lab with
jupyter lab, and in Jupyter lab
open a notebook.
Open the EODAG tab on the left side of the JupuytuerLab interface by clicking on that icon.
With displayed search form, you can enter select your data geographically and apply some search criteria:
- Product type: the searched product type. For each entry of the drop-down list, a tooltip is displayed at hovering time with corresponding description.
- Start date: minimal date of the search temporal window.
- End date: maximal date of the search temporal window.
- Max cloud cover: maximum cloud cover allowed in search results in percent.
- Additional parameters: used to enter key-value pairs criteria for the request.
You can draw multiple extents, or use none. Each extent can be a rectangle or a free polygon. Product type is mandatory. Other criteria are optional.
Once search criteria are filled out, click on the "Search" button to proceed to next step. At the end of the search, a popup opens and displays results.
The results overview popup is compopsed of 3 parts:
- a map showing products extent
- a table listing products
- a pane containing metadata for currently selected product.
The results table allows you to access product metadata by clicking on the desired product line. The magnifying glass button allows you to zoom in on the product's in the map view. By scrolling down in the list of results, the search is automatically restarted to retrieve the following results.
In the metadata view, clicking on the thumbnail displays it in native resolution. Clicking it again reduces its size again.
Apply to the Jupyter notebook
If the search result is correct, clicking on the "
Apply" button will insert the Python eodag code in a new cell
after the selected cell of the currently open notebook. The popup is automatically closed. From there, it is possible
to work in the notebook on the search results by executing the eodag search.
Here is an example of generated code:
from eodag import EODataAccessGateway, setup_logging setup_logging(1) # 0: nothing, 1: only progress bars, 2: INFO, 3: DEBUG dag = EODataAccessGateway() geometry = "POLYGON ((0.550136 43.005451, 0.550136 44.151469, 2.572104 44.151469, 2.572104 43.005451, 0.550136 43.005451))" search_results, total_count = dag.search( productType="S2_MSI_L1C", geom=geometry, start="2021-08-01", end="2021-08-11", cloudCover=17, )
Please refer to the user manual notebook for results usage examples.
