Sentinel-2 Burned Area Analysis

This service takes as input a pair (pre-event and post-event) of Sentinel-2 MSI L2A products and generates a Burned Area Analysis map and NIR/SVWI RGB composites for the two input Sentinel-2 acquisitions.

EO sources supported

  • Sentinel-2 MSI L2A

Output specifications

  • Burned Area Analysis map
  • NIR/SVWI RGB composites
  • Reproducibility notebooks

This tutorial will describe the processing of a pair of Sentinel-2 MSI images to generate a Burned Area Analysis map and NIR/SVWI RGB composites for the two input Sentinel-2 acquisitions on the GEP.

Select the processing

  • Login to the platform (see user section)
  • Select the processing service “Sentinel-2 Burned Area Analysis”:

The “Sentinel-2 Burned Area Analysis” panel is displayed with parameters values to be filled-in.

Fill the parameters

Pre-event product reference

  • Select the Sentinel-2 data collection in the EO Data button.
  • Select the area for which you want to do an anlysis, e.g Corumba in Brasil.

Note

pre-event input can be picked up directly by using the following text filter: S2A_MSIL2A_20190815T140101_N0213_R067_T21KUU_20190815T214633

Post-event product reference

Pick one of the results having the same track, then drag and drop one of the results in the Input reference field:

Note

post-event input can be picked up directly by using the following text filter: S2B_MSIL2A_20190830T140059_N0213_R067_T21KUU_20190830T180923

Area Of Interest in WKT

  • Click on the Magic tool wizard and select AOI. The input parameter is automatically filled with the WKT representing the area selected.

Note

you can also specify manually a different AOI in WKT format, or draw a new area on the map using the search tool and get its value from the Magic tool wizard

Run the job

  • Click on the button Run Job and see the Running Job
