To study the impact of pesticide uses in agriculture on human health, data were collected to represent the spatial dynamics of pesticide uses over time: i) a database of agricultural practices regarding the use of pesticides and their evolution over 50 years for the main three gr... |
Dufleit, Victor; Barbarin, Florian; Henaff, Axel; Taizieres, Benjamin; Bonnal, Vincent; Cattan, Philippe; Chery, Jean-Pierre; Tran, Annelise, 2024, "Banana, sugar cane and market gardening plots, Guadeloupe, 1987", https://doi.org/10.18167/DVN1/LYC8N8, CIRAD Dataverse, V1
A map of banana, sugarcane and market gardening plots was produced from scanned paper maps of Guadeloupe in 1987 published by the French Agriculture and Forestry Department. Paper maps have been digitized and georeferenced to be integrated into a Geographic Information System env... |
Dupuy, Stéphane, 2023, "Mayotte - 2022 - DHM from Pleiades stereoscopic images", https://doi.org/10.18167/DVN1/4EAKVD, CIRAD Dataverse, V2
The data published here are derived from Pleiades images acquired by the Dinamis system. These data are produced for the Biotamaya project. - The DSM (Digital Surface Model) is calculated from Pleiades images acquired in stereoscopic mode. The images were acquired in 2022 (betwee... |
