The MAIL geoportal includes the following applications:·       Marginal land identification on EU level based on existing open access datasets: The application can be used display the original marginal land classification that was performed during the project or to create new classification based on the selection of different layers and indicators.·       The Carbon Sequestration Capacity groups layer displays the classification of marginal land in five carbon sequestration capacity classes.·       The Decision support system can provide insight in the selection of the most suitable marginal land area for a reforestation project using a carbon calculator tool, a carbon projection tool, an afforestation cost calculator, and potential suitable tree species selection tool.·       The identification of marginal lands using satellite images generated enhanced marginal land maps for a selected time period in a specific area.·       The multi temporal analysis tool can provide information regarding deforestation detection, forest areas monitoring, and afforestation/reforestation project monitoring.
