Crop Loss Detection using NDVI anomalies

3rd Extending The Market Challenge (EM3)
ethz2-2.jpg

Challenge Description

The goal of the Challenge is to have a first evaluation of crop loss based on time series analysis of a vegetation spectral index derived from satellite images (Normalised Difference Vegetation Index - NDVI) for the chosen parcels. Seven data pipelines were defined under this challenge:

  • Landsat-7 and -8 NDVI time series (Ref. EXT-02-03-01)
  • NDVI growing season statistics time series per pixel (Ref. EXT-02-03-02)
  • NDVI long term averages of growing season statistics time series per pixel (Ref. EXT-02-03-03)
  • NDVI anomalies of growing season statistics time series per pixel (Ref. EXT-02-03-04)
  • NDVI growing season time series per parcel (Ref. EXT-02-03-05)
  • NDVI long term averages of growing season time series per parcel (Ref. EXT-02-03-06)
  • NDVI anomalies of growing season time series per parcel (Ref. EXT-02-03-07)

The Challenge Promoter is Fidelidade, Companhia de Seguros S.A. (https://www.fidelidade.pt)

Results

The results below are divided into Software Repositories, Online Services and Data Products Repositories.
In case you would like to get in touch with us about specific results, please use the indicated reference codes (e.g. WFP-01-01-01).

 

Software Repositories

There are two categories of software repositories generated for the Challenge:

  • GitLab repositories are hosting the reference software code, for use by the team members of a challenge only (restricted access)
  • GitHub repositories are hosting the public software code (mirrors), for engagement and collaborative work with the broad community of software developers (public access)

Follow the links below to proceed to one or the other, and find an "Ellip Workflows (ewf)" software application implementing a data processing function.
You can adapt this software to your own context, commit a contribution to the related repository, or engage with the BETTER consortium to run it for a specific purpose (new area of interest, ...) by requesting Cloud resources to support (at) terradue.com

Data Processing as-a-Service

There are two categories of "Data Processing as-a-Service" application packages created for the Data Challenge:

  • Data Processing Pipelines are controlling full EO data production campaigns, for use by approved members of a challenge only (authorized access),
  • On-demand Processing Services are controlling individual EO data processing jobs, also for use by the approved members of a challenge only (authorized access).

Follow the links below to proceed to one or the other, via a dedicated Geobrowser application providing web access to one or the other of the Data Processing services.
You can engage with the BETTER consortium to request authorized access via support (at) terradue.com

Data Product Repositories

There is a dedicated client App publicly available for the visualization of the data products resulting from EO data processing challenges.

The results can consist of:

  • Validation data: small amount of data products generated for approval by the Challenge promoter
  • Production campaign data: full-time series/collection of data products answering the Challenge promoter question about Earth Observation data being used to help solve global societal challenges
