As a part of work package T3 in ISTER project, Geodetic institute of Slovenia is in charge of the design and production of the innovative cartographic web application – the Atlas of Roman routes in Danube Region. The Atlas is more than just a cartographic Atlas; it is built on a widely-documented data catalogue of Roman Routes and settlements which can be geo-visualised, analysed, managed, exported and disseminated through the platform’s functions. Geodetic institute of Slovenia designed guidelines focused on the spatial management component where data preparation, app functionalities, organization and definition of layers are described. As a part of work package T3 in ISTER project, Geodetic institute of Slovenia is in charge of the design and production of the innovative cartographic web application – the Atlas of Roman routes in Danube Region.
