EuroRegionalMap How to Succeed in Overcoming National Borders

摘要

EuroRegionalMap (ERM) is a pan-European multifunctional topographic reference dataset at scale 1:250 000 based on national contributions from EuroGeographics member organisations. In one of its regional production groups data providers of eight Central European countries faced the challenges of harmonizing their national medium-scale databases in matters of content, geometry and quality standards. This paper presents a progress report about the chosen approach and the realiza-tion of this multinational co-production. In this context the used project organisa-tion and the given ERM specifications and guidelines are introduced. Thereafter the different national ways and means of deriving an ERM dataset by converting national data to ERM are exemplarily shown. Furthermore, to demonstrate a best practice approach the edge-matching of data at the cross-border area of countries to reach a seamless dataset is presented in more detail. The last focus is set on how quality assurance is achieved. In a validation phase all data is checked by several validation procedures to identify errors in the data's logical structure as well as to insure feature/attribute compliance with the current ERM specifications. On-going changes and future developments complete the paper.
