BASIC CORE South Tyrol

The project has its roots in a precise and simplified cartographic updating methodology introduced by the Consortium of Municipalities of the Province of Bolzano in the early 2000s. This methodology, which was consolidated over the years, could no longer be applied following the adoption of the Territorial Data Catalogue (Ministerial Decree 10.11.2011 “Technical rules for defining the content specifications of geotopographic databases” and subsequent amendments) due to the complexity and articulation of the new national model. The primary objective of the project was to research and define a minimum set of information that could adequately describe the territory within the typical use context of the public administration, ensuring its sustainability in terms of the ability to keep it updated and aligned with the transformations of the territory. Simplifying the definition and understanding of the basic technical layer that every public administration producing geographic data must guarantee within their institutional activities for geotopographic databases is a fundamental step to adequately support territorial management. Lightened of the informational content already managed by the Provincial Administration within archives or sectoral Information Systems, and consequently already included in existing and consolidated maintenance and updating flows, as well as everything that can be considered three-dimensional data nowadays obtainable through faster and more accurate systems, the Basic Core (BC) specification was produced by reorganizing and simplifying the information levels contained in the National Territorial Data Catalogue with reference to the identified minimum subset of required information known as the National Core (NC). To make it practically usable, only the themes considered objectively useful and easily updatable were included in the Basic Core. Our presentation will outline the key points that enabled the design of the Basic Core content specification and illustrates the technological tools developed, as well as the automatic transformation and simplification procedures that led to the significant reduction in the number of object classes provided by the National Core (from 59 to only 23), demonstrating that the Basic Core project is not a merely theoretical exercise, but a practical and concrete application currently tested and successfully used in South Tyrol. The specifically developed Dashboard for managing, correcting and updating the provincial Geotopographic Database, built on the basis of this new simplified specification, will be explained in detail. This dashboard allows effective operation on every management aspect, including the crucial task of sharing maintenance responsibilities between the Provincial and Municipal levels, thus ensuring the full efficiency of this fundamental geographic base. Particular attention will be given to illustrating the guided editing functionality available directly from the online interface, as well as the options for creating and exporting QGIS projects. QGIS projects are designed to perform the most significant and advanced corrections and/or updates. We will conclude the overview of this innovative system with a demonstration of the processes for reimporting and validating the updated data. Finally, practical cases in which the Basic Core has been used will be presented, as well as future developments, already planned and those still under evaluation, that the system will receive in order to refine and make its use more robust.
