Itasy, Vakinankaratra - Madagascar - 2023 - Land cover reference spatial database

This reference database in vector format (ESRI shape format) is organised according to a multi-level nomenclature. It is used to train an image classification algorithm with a view to producing land use maps for the Itashy and Vakinankaratra regions as part of the DINAAMICC project. Each GPS point was converted into a polygon by digitising the boundaries of the corresponding plot on the Google Satellite background and/or the mosaic of Spot 6/7 images acquired in 2022 and 2023 during the growing season. In addition, other polygons were digitised by photo-interpretation of the images. The database covers the entire study area in order to be representative of existing crop types and perennial structures. The final database contains 3726 polygons.
