GeoMedia WebMap improves integration and access to regional cartographic data.

The Region of Friuli-Venezia Giulia in Italy recently deployed its Internet Visualizer Catalogue, an enterprise Web-based cartographic catalogue that uses Intergraph's cartographic solutions to integrate and visualize geospatial data and information such as orthophotos, digital terrain models, and digital maps of various scales. This system enables the geographically dispersed organizations within the region to share and integrate geospatial information, resulting in increased efficiency of data collection as well as improved access to a broader array of cartographic and related information. The Internet Visualizer Catalogue was developed for the Region of Friuli-Venezia Giulia by Insiel, Finsiel Group -Telecom Italy, the company that manages most of the IT implementations for the region's local authorities.

Responsible for the maintenance and accuracy of the region's cartographic knowledge and resources, the Regional GIS and Cartography Office faced the challenge of coordinating a 20-year collection of data originating from various sources and platforms in numerous formats. The overwhelming influx of disparate raster and vector data often resulted in delayed distribution of information needed for operational decision making to regional organizations. Users working in the Regional Environmental Office (REO) relied heavily on digital maps and orthophotos to monitor polluted areas, dumps, and water conditioners, and users in the Regional Transportation Office (RTO) needed updated cartographic information to perform daily operations for road and railway networks. Both groups required a timely method of acquiring updated cartographic data. In addition, there was a growing demand from the regions and the users to visualize the data between the two. The agency wanted a solution to correlate raster and vector data of varying scale and efficiently deliver it to multiple users in diverse organizations for enterprisewide access.

Using Intergraph's GeoMedia WebMap, the Internet Visualizer Catalogue is distributed to all cartographic product users within the region, allowing them to integrate their own information as well as access data available from other users. Because GeoMedia technology is based on OpenGIS standards established by the Open GIS Consortium (OGC), all data within the region can be brought together regardless of platform, thereby increasing productivity and efficiency. Further advantages of the new system include the reduction of duplicate data sets, a broader set of maps with varying thematic content, and an increased level of communication between the Regional GIS and Cartography Office and external user organizations.

By simply logging on to a centralized Internet or intranet portal, users now can view both raster and vector data sets at the same time, depending on their cartographic scale. For example, features such as administrative boundaries, rivers, and hydrological basins can be compared with an orthophoto. Alternatively, geographical locations of the regional aquifer network or mountain cableways can be overlaid with digital maps. The Internet Visualizer Catalogue also includes functionality to permit identification of features such as linear and area measurement, viewing of attribute values, querying of specific map areas, and spatial analysis of proximity and routes.

The Internet Visualizer Catalogue has also provided new opportunities for using geospatial information in the region. In addition to providing more in-depth spatial analysis capabilities for current cartographic and administrative professionals, the catalogue has attracted an increased number of users, including new users who focus on the region's forestry, agriculture, transportation, and geology.
