Applicability of the LPIS data approach in Croatian SGA

The Croatian State Geodetic Administration (SGA) is a key player for the implementation of the INSPIRE directive. It deals with cadastral and topographical data, geodetic activities, collecting new data, the design of spatial information systems and solutions, distribution of spatial data, services and standardized finished products and their archiving. The JRC Mars unit has since 2010 designed and implemented an approach to exchange LPIS data between all EU Member States and the European Commission. The similarity between their respective roles merits investigating the potential for sharing experience. The obvious field for application of JRC’s experience would SGA’s implementation of the quality assurance and upkeep procedures of topographical and cadastral data. For Quality management, data exchange could be designed so that data is entering into the system through a gateway with automated procedures such as quality checks. A system must be designed in a way that ambiguity is prevented and that self-assessment control system are present. This allows to producer to perform an independent inspection on a sample generated by SGA. Another result of such a system is a record of additional quality metadata. The LPIS upkeep methodology approaches the maintenance from a feature and message perspective. This system describes how individual reference parcels should be processed in the case of reported changes. The final objective is that features attribute values are correct and complete and reflect the current situation on the ground regarding to the valid rules. Similar approaches could be designed for the update of topographic SGA database which contains land cover, introducing a more dynamic management of the “layer”. Knowing the current implemented processes and solutions this paper is bringing some potential improvements for data management and control system
