Map of predicted Xenopsylla Genus Flea Index (GFI) based on climatic and environmental variables, Reunion Island. Xenopsylla cheopis and Xenopsylla brasiliensis are known vectors of Rickettsia typhi, a pathogenic bacterium causing murine typhus, a neglected zoonotic disease. GFI... |
Dupuy, Stéphane; Gaetano, Raffaele, 2020, "Reunion island - 2019, Land cover map (Spot6/7) - 1.5m", https://doi.org/10.18167/DVN1/YZJQ7Q, CIRAD Dataverse, V1
As part of THEIA (the French Data and Services center for continental surfaces) CIRAD's TETIS research unit is developing an automated mapping method based on the Moringa chain that minimizes interactions with users by automating most image analysis and processing. The methodolog... |
Roche, Mathieu; Helmer, Thierry; Martin, Pierre; Chaminuka, Petronella; Dimitriou, Ioannis; Csorba, Adam; Lindsten, Agneta; Lundén, Tomas; Van Boheemen, Peter, 2020, "LEAP4FNSSA (WP3 - KMS): Terminology for KEOPS", https://doi.org/10.18167/DVN1/GQ8DPL, CIRAD Dataverse, V1, UNF:6:q+wkvuEpP3iSokRJHqL1qA== [fileUNF]
In order to highlight terminology to integrate in the LEAP4FNSSA KMS (Knowledge Management System) called KEOPS (Knowledge ExtractOr Pipeline System), a dedicated terminology to the LEAP4FNSSA project has been extracted with a text-mining tool (BioTex) from a corpus dealing with... |
