Sinico, Marion; Russeil, Valentin; Huat, Joël; Le Mezo, Lionel, 2022, "Zones de production maraichères et fruitières à La Réunion (2021)", https://doi.org/10.18167/DVN1/JBQV7I, CIRAD Dataverse, V1
Cette étude réalisée en 2021 s’inscrit dans le cadre d’un projet de recherche portant sur l’autonomie alimentaire-énergétique de La Réunion porté par l’ADEME, le CIRAD et l’Université de La Réunion visant à simuler l’évolution d’indicateurs d’autonomie alimentaire-énergétique, en... |
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... |
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... |

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... |
