Konzeption und prototypische Entwicklung eines GIS-gestützten Werkzeugs zur Transformation von umweltrelevanten Geodaten auf INSPIRE-Referenzdatensätze

Abstract

Within Europe the usage of different spatial data sets causes problems. This is true especially for cross-border use of spatial data. Usually the existing spatial data sets are available in many different formats. Furthermore there are cultural, organisational, political, financial and legal constraints to be solved. To solve these problems the directive Infrastructure for Spatial Information in Europe (INSPIRE) was developed by the European Union. This directive is used to support the decision making processes for political concepts and measures which have direct or indirect impact on the environment. The realization of INSPIRE takes place in different parts (annex). Within these parts there are Data Specifications (DSI) defined. The DSIs of the Annex I are already realised. But the DSIs of the Annexes II and III are not yet realised.

Options for the creation of spatial data sets are analysed based on INSPIRE reference data sets. For that purpose appropriate tools have been designed. A GIS-based tool has been developed that enables the conversion of existing spatial data to an INSPIRE-referenced shape. For example a spatial data set covering a topic from Annex III can be used. If the spatial data set contains vector data, the Administrative Units defined in Annex I are used as reference system. If the spatial data set contains raster data, the Geographic Grid Systems also defined in Annex I are used as reference system. With these reference systems an INSPIRE-Compatibility can be realized which means that the spatial data are converted to a form which is similar to INSPIRE. This conversion supports the data interoperability at European level.

In this diploma thesis a tool has been designed and (partly) implemented as a prototype. Existing spatial data sets have been converted to an INSPIRE referenced form. Such a spatial data set cover any of the topics contained in the INSPIRE Annex III. The identified and discussed scenarios demonstrate how current and already implemented topics can be used to make spatial data sets compatible to INSPIRE. The parts of the developed concept have been implemented in a prototype. By means of the two elaborated scenarios Regional climate change and Environmental monitoring the tool has been evaluated with practical data.
