Renou, Alain; Idrissa, Tereta; Goebel, Regis; Jean, Janine; Brévault, Thierry; L. Llandres, Ana, 2019, "Données brutes sur l'effet du taux d'ecimage de cotonniers sur les populations de chenilles de la capsule", https://doi.org/10.18167/DVN1/PCTL8J, CIRAD Dataverse, V1, UNF:6:X/PzKC++9lHmdTGOb6qU0A== [fileUNF]
The aim of the experiment was to study the effect of different pest control strategies (most of them involving plant topping) on the population of cotton bollworms, Helicoverpa armigera, Diparopsis watersi and Earias spp, in Mali. The impact of these pest control practices on the... |
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... |
Espinosa, Luis; Brancheriau, Loic; Prieto, Flavio; Lasaygues, Philippe, 2019, "Ultrasonic tomographic reconstruction considering wood anisotropy", https://doi.org/10.18167/DVN1/GI8LSW, CIRAD Dataverse, V1
We proposed an approach to solve the inverse problem for tree imaging, using a method based on ultrasound travel-time tomography and adapted to the anisotropy of wood material. The proposed inversion procedure was developed between 2015-2018. The method considers the dependency o... |

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... |

Londoño Villegas, Mónica María; Le Mezo, Lionel; Dupuy, Stéphane, 2019, "Base de données spatiale pour l'apprentissage - 2016-2017- La Réunion", https://doi.org/10.18167/DVN1/HM9QNL, CIRAD Dataverse, V1
La base de données pour la période 2016-2017, est constituée de 2650 parcelles. Nous l'utilisons pour calculer une carte d'occupation du sol à partir d'image satellites. Nous avons sélectionné de façon aléatoire 20% des parcelles de chaque classe pour constituer une base de donné... |
