sowohl valider Geodaten wie auch einer breiten Partizipation bedürfen. Dieser Beitrag zeigt anhand des „Wadden Sea Region Planning Portal“ (WSRPP), einem trilateralen Web-GIS, exemplarisch auf, wie vorhandene Geodaten unterschiedlicher Herkunft in einem einheitlichen Standard zusammengeführt werden können und damit die Entwicklung integrierter und multilateraler maritimer Raumplanungsprozesse unterstützen. Die Struktur dieses Beitrags gliedert sich dabei wie folgt: Erstens wird die Fallregion anhand ihrer ökologischen, kulturlandschaftlichen und sozioökonomischen
The crowd-sourcing approach should be implemented into a new historical geoportal of Poland due to its increasing potential in WebGIS. Registered users will be able to acquire spatial data from various map series. As it requires feature class harmonization, a common symbol classification should be proposed. It will be based on chosen topographic maps of Polish land from the 19th and 20th centuries. Feature classes derived from archival maps will be standardized and reclassified, but with no information lost. This will be done in four steps which require: data acquisition, map content harmonization, feature class typification and attribute table elaboration. In addition, four methods of data harmonization can be distinguished: symbol sequence, semantic analogies, spatial relations and a combined method. The paper covers the elaboration of two thematic layers - roads and railways based on three topographic maps (Austrian 1:75 000, German 1:100 000, Russian 1: 126 000).

Earth Observation (EO) products are widely used by geospatial society. Over the last years a number of new applications of satellite imagery were proposed. This led to an increased interest in EO products, not only from researchers but also from companies and individuals. The authors constitute the essential part of the team that created the marine, web-GIS system - SafeCity GIS - for dissemination of data obtained from a 1.5 metre HRPT-MetOp satellite ground receiving station. To increase the operationability of the system the authors successfully attempted to broaden the offered functionality by integration with Service Support Environment (SSE). Due to this, EO products for the Pomeranian Region are served as web-services; amongst them there are True Color imagery, meteorological, algae monitoring and fire-detection services. The authors present the created solution for web service support for GIS system based on Service Support Environment and discuss its advantages and disadvantages.
Spatial data have become very important phenomena within the last decade in Europe due to a strong support from the political spectrum with regard to related legislation and resulting in financial support to several research, educational, and enlargement projects. INSPIRE (Infrastructure for Spatial Information in the European Community) Directive indeed defines the principles for the harmonization of spatial data infrastructure in the European community, including Land Use and Land Cover data themes. INSPIRE defines a methodology on how to transform datasets to common data models, but it does not cover the process of data collection and update, because it is out of its scope. Evaluation of the Land Use dataset derived from remote sensing products complemented by fieldworks has been realized since 2006 by Eurostat within the LUCAS (Land Use and Cover Area frame Survey) project. The work presented in this paper follows the LUCAS fieldwork methodology, which was applied during the fieldwork in July 2014 in the City of Zagreb (Croatia), to use at the local (municipal) geoportal level. The surveying groups collected point features with the following data type attributes: Land Use codes defined by HILUCS (Hierarchical INSPIRE Land Use Classification System) and optional Land Cover codes defined by LUCAS classification. In addition, photographs representing the observed areas were collected by cameras embedded in the mobile GIS platforms. An update of original topological layer was performed and Web GIS components for sharing the newly developed datasets were implemented. The results presented provide a suitable proposal for fieldworks methodology and updates of a land use database in line with the INSPIRE directive applicable at a local spatial data infrastructure level.
