Biography
Anna Lleopart is head of the Cartographic databases Unit at the Cartographic and Geologic Institute of Catalonia, in Barcelona. She is responsible for the design of cartographic databases and the production of ICGC Street and address database of Catalonia. She has large experience in data modelling and has participated in several standardization working groups, both national and international. She has been the facilitator of the Cartographic Coordination Commission of Catalonia working group responsible for specifying the Municipal Address Dataset of Catalonia and is currently the facilitator of the working group specifying the Road Network dataset, both compatible with INSPIRE specifications.

In the last decade, the hardware and software potential has increased exponentially so that, it is possible to man-age and deal large amounts of data, especially spatial data; at the same time, the number and diversity of users as well of channels to access geographic information have also increased significantly. In parallel, INSPIRE deployment is challenging national mapping agencies which can take it as an opportunity to modernise their products. All these factors lead to modify the data models and to define updating polices for adapting the services and products to the customers needs. The goal is to offer to the user the chance of defining an area of interest, the type of updating delivery (incremental, historical) and the thematic subsets, for visualizing, accessing, downloading or acquiring the information. The presentation will explain how the Institut Cartografic i Geologic de Catalunya (ICGC) existing models are improved taking into account the INSPIRE data specifications. The addition of an unique and persistent ID, the temporal information or metadata at object level is an efficient way of managing the change of updating policies from dataset or mapsheet criteria to themes, layers of information or buffers around changes.
All these aspects will be detailed by each one of the key changes implemented in ICGC data models:
• Object ID: unique and persistent feature identifier.
• Temporal information: life-cycle information and revision date.
• Object metadata: name and date of the updating information sources.
Finally, it will be given an overview of the production workflow and the designed tools for ensuring the man-agement of the specific characteristics of the data model and for optimizing the updating process.
