Degenne, Pascal, 2021, "Risque de ruissellement selon des pentes à 7% sur l'île de La Réunion", https://doi.org/10.18167/DVN1/FSSY6B, CIRAD Dataverse, V1
Estimation d'un risque de ruissellement vers les cours d'eau du Domaine Public Fluvial de l'île de La Réunion selon des pentes supérieures ou égales à 7%. Le calcul de risque de ruissellement est effectué de manière itérative, en partant des cours d'eau et en progressant le long... |
Grimaud, Yannick; Tran, Annelise; Benkimoun, Samuel; Guis, Hélène; Garros, Claire, 2021, "Model of Culicoides spatio-temporal dynamics, Reunion Island", https://doi.org/10.18167/DVN1/LUFIF6, CIRAD Dataverse, V1
A population dynamics model of hematophagous midges of the genus Culicoides has been developed for Reunion Island. It simulates the abundance of each of the five Culicoides species (C. bolitinos, C. enderleini, C. grahamii, C. imicola and C. kibatiensis) present in Reunion Island... |
Dupuy, Stéphane, 2021, "Reunion Island - 2019, reference spatial database", https://doi.org/10.18167/DVN1/T3GIW2, CIRAD Dataverse, V1
The reference spatial database for 2019 contains 5142 plots. We use it to calculate a land use map from satellite images. It is organized according to a nested 3-level nomenclature. This is an update of the 2018 database. The sources and techniques used to build the database by l... |

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... |
Tran, Annelise; Mangeas, Morgan; Demarchi, Marie; Roux, Emmanuel; Degenne, Pascal; Herbreteau, Vincent; Dehecq, Jean-Sébastien, 2019, "ALBORUN - Modèle de la dynamique de population des moustiques Aedes albopictus à la Réunion", https://doi.org/10.18167/DVN1/XF2I3L, CIRAD Dataverse, V3
[FR] ALBORUN est un modèle de la dynamique de population des moustiques Aedes albopictus, développé à l'Ile de la Réunion. Il a été développé avec le langage métier Ocelet, langage dédié à la modélisation de dynamiques spatiales doté d'un environnement de développement de modèles... |
Dupuy, Stéphane; Gaetano, Raffaele, 2019, "Reunion island - 2017, Land cover map (Pleiades)", https://doi.org/10.18167/DVN1/RTAEHK, CIRAD Dataverse, V3
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... |
Dupuy, Stéphane, 2019, "Reunion Island - 2017, reference spatial database", https://doi.org/10.18167/DVN1/TOARDN, CIRAD Dataverse, V3
The reference spatial database for 2017 is composed of 6256 plots. We use it to calculate a land use map from satellite images.It is organized according to a nomenclature offering 3 levels of precision. We randomly selected 20% of the plots in each class to build a validation dat... |
Dupuy, Stéphane; Gaetano, Raffaele, 2019, "Reunion island - 2018, Land cover map (Pleiades) - 0.5m", https://doi.org/10.18167/DVN1/WKAJZO, CIRAD Dataverse, V1
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 methodology uses jointly a Very High Spatial Resolution image (Spot6/7 or Pleiades) and on... |
Dupuy, Stéphane, 2019, "Reunion Island - 2018, learning spatial database", https://doi.org/10.18167/DVN1/8QJABD, CIRAD Dataverse, V1
The spatial learning database for 2018 contains 5620 plots. We use it to calculate a land use map from satellite images. It is organized according to a nested 3-level nomenclature. The sources and techniques used to build the database by land use groups are described below: For a... |
