UPDATING OF VECTOR DATABASES AT THE INSTITUT CARTOGRAFIC DE CATALUNYA

Since 1985 the ICC has been creating and updating topographic and thematic databases and deriving cartographic products using automatic symbolization and semi-automatic generalization. After describing the workflows used to update the ICC databases and the derived products, the paper describes the main aspects of ongoing projects for optimizing updating processes such as extending the data models for supporting incremental updating and versioning, the mechanisms for conveying updated data to the users, and the web based harvesting of information. In addition, the paper describes the prototype developed together with the Harbour Authority of Barcelona and the City of Barcelona for the collaborative updating of topographic data at large scale, and the project of updating the Street database that will be developed together with the municipalities.
