Abstract
This work is the result of the tests performed about designing, realization and disseminating on the Web a 1:10000 scale topographic database following the “Intesa Stato-Regioni” specifications. The first phase of the work concerned the study of the documents produced by the Working Group 01 of the Intesa for general-purpose topographic databases, on which ground we based the realization of a topographic DB of an area in southern Sardinia. The database follows the Intesa specifications regarding layers, themes and classes, including all required spatial components for building and rendering in 3D the topographic database. This entire process was performed in the GCarto-GDS software by Geosoft. From these first phases we were able to analyze the problems linked both to the interpretation of the Intesa specifications, and to the restitution of the requires spatial components, evaluating the increase of workload and produced data. The further phase concerned publishing the topographic database on the Internet. Here, too, we followed the Intesa specifications indicating GML as the spatial data interchange format. The topographic database was published using MapServer, and the resulting data were exported to GML with various open-source tools.Items in DSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
