At present and within a context of integrated coastal management, the population growth and increasing land pressure with their subsequent land cover changes on the Thau basin make this territory an important policy issue. In order to cope with the issues at stake the Thau regional authorities have entrusted SMBT from 2006 onwards with the joint development of several planning tools (SCoT, SAGE and Natura 2000 Convention) to conduct an integrated approach to territorial development. The aim of the present paper is to present the methodology used for mapping the initial 2012/2013 land use cover of the Thau basin from Pleiades imagery. This map will be a basic input for the observatory of the Thau territory and support the implementation of planning tools. The methodology was divided into two parts: first, a photo-interpretation approach for artificialised area mapping and evolution monitoring over several years and second, a remote sensing detection approach with the achievement of an object-oriented classification of agricultural and natural environments. This methodology allowed to obtain an up-to-date land use cover according to a 4 level typology adapted from the CORINE land cover nomenclature. This land cover will be updated every second year to help produce assessment and monitoring indicators for the Thau territory.
