Management of integrity constraints for multi-scale geospatial data sources

Abstract

In order to improve readability and understanding of geospatial data, some representations of spatial information can be transformed using cartographic generalization, which generates multi-scale data. These data types have been treated since the 90's by multirepresentation databases, which are intended to allow that different views of the same object be stored and linked, enabling navigation across scales. One of the main goals is to guarantee the availability of information without any contradiction between the different representations. The concept of scale goes beyond issues of space, since it also applies, for instance, to the time scale. This project aims to study and develop a system to manage integrity rules for multi-scale situations, related to geospatial data.
