  • Masae processed likewise :

  • Extraction of pixel-level information from Sentinel 2 imagery and generation of indicators data for Niamey wood supply basin

  • Use of Machine learning to classify each pixel of the different images obtained depending on 8 land use classes

  • Pre-/post analysis of the images allowing the team to identify areas where land use had changed between 2019 and 2020, thereby identifying deforested areas

  • The machine learning algorithm used to classify pixel by land use class achieved 99.5% accuracy. The team was able to detect deforested and degraded areas consistent with ground truth collected by a third party



Deliverable

  • A platform has been developed to visualise the data. It is available here
