The session aims to focus on understanding, modelling, analysing and improving each step of the process chain for producing digital environmental surface grids (terrain, climate, vegetation, etc.) able to be used in Ecosystem Services issues: from the sensors (in situ as well as Earth Observation data) to the map dissemination. In this context, topics as data acquisition/ingestion, data assimilation, data processing, data homogenization, uncertainty and quality controls, spatial interpolation methods, spatial analysis tools, derived metrics, downscaling techniques, box-tools, improvements on metadata and web map services are invited. Spatio-temporal analyses and model contribution of large series of environmental data and the corresponding auxiliary Earth Observation data are especially welcome as well as studies that combine cartography, GIS, remote sensing, spatial statistics and geocomputing. A rigorous geoinformatics and computational treatment is required in all topics.
