Analamanga, Itasy, Vakinankaratra - Madagascar - 2016-2017, Land cover map

The land use maps published here were produced for the municipalities studied by the DINAAMICC project during the period 2016-2017 (based on data previously collected by other projects). They cover the entire Itasy region and part of the Analamanga and Vakinankaratra regions. This period was chosen for the availability of the field surveys needed to train and validate the algorithms for producing land cover maps. The data used are cited in the "Related datasets" category below. The choice of a simplified nomenclature divided into two hierarchical levels made it possible to create a database of 4,245 polygons. The images used are the Sentinel-2 level 2A images distributed by THEIA acquired between September 2016 and June 2017. Considering the distribution of the municipalities studied by the project, the available field surveys and the absence of very high spatial resolution images over the area during this period, it was decided to use the Iota² chain on 4 Sentinel-2 tiles. The overall accuracy of the maps obtained is 87% for level 1 and 78% for level 2. Download the attached document for detailed explanations of the methodology.
