Kawk as an early attempt at integrating spatial data of regional significance
While the European Union is working on implementing the INSPIRE project (Infrastructure for Spatial Information in Europe), it is worthwhile to recall an undertaking from nearly a decade ago, namely the computer-based atlas of the Cracow Province (Komputerowy Atlas Województwa Krakowskiego . KAWK). The project was co-financed by the Committee for Scientific Research, and developed by interdisciplinary team of researchers from the Academy of Mining and Metallurgy and the Jagiellonian University of Cracow. Today KAWK may be perceived as the first Polish attempt at integrating spatial data of regional significance. The attempt was successful and largely parallel to the direction adopted currently by the INSPIRE Directive. The primary objective of the KAWK project was to integrate cartographic, remote sensing and statistical data, and its beneficiaries were public institutions engaged in regional development. It was considered whether KAWK should be an electronic atlas, a collection of once plotted maps, or a spatial data base. The latter option offers a wider range of possibilities . it stores data and enables their processing using the functionality of GIS. The outcome may include both maps and comparative lists, charts, or sets of data for other GIS users. It was agreed that the database should be the model for KAWK. This was a brave decision, as in the second half of the 1990.s GIS technologies were extremely complex and incomplete at the same time. The database was split into groups of subjects: general geographic layout (base map), natural environment, and socio-economic situation. Each group would use source data to a varying degree. The general geographic layout was based on topographic maps to scale 1:50 000. Due to the fact that the maps were out of date, changes were introduced, based on SPOT satellite images and serial photographs. An important outcome of the project is emphasizing the necessity to develop a uniform model of spatial data in the form of database applicable countrywide. The paper presents two strategies of defining objects in spatial data base. It has been evidenced why the strategy of developing more abstract models proves more favorable than the determination of large numbers of detailed objects. The issue has been illustrated with an example of road network. The area for testing KAWK covered the Krakow Province, one of the 49 provinces of the administrative division existing at that time. The administrative reform implemented in 1999 was followed by modification of KAWK from a relatively complete project into a starting point for GIS for the new Małopolskie Province, which included the area of the past Krakow Province. The entire KAWK project was taken over by the marshal of the Malopolska Region who shortly turned it into the geographical data base for the entire province. Some of the data are accessible at http://www.wrotamalopolski.pl.
