“…To meet these demands, a Web-based geographical information system (WebGIS) with additional functions for integrating, visualising and analysing data seems to be an appropriate solution. This could help to solve problems resulting from the use of different data types, varying analytical methods, incomplete environmental monitoring and the lack of metadata information (Schröder et al 2002). Problems in data harmonisation and management should be reduced and prevented by using a WebGIS.…”

The forest monitoring in North Rhine-Westphalia consists of the forest condition evaluation, the foliar chemistry survey and the soil condition evaluation which are parts of the Germany-wide Level I network. Additionally, there are eight permanent sampling sites of the Europe-wide Level II network (UNECE ICP Forests). These data should be integrated and analysed by multivariate statistical methods. But there are problems regarding the access to data for scientific purposes. Accordingly, a Web-based geographical information system for compiling, management and analysis of forest monitoring data was implemented based on Open Source software to improve and harmonise data handling, visualisation and analysis.

“…The surveillance of GMO (Genetically modified organisms) dispersal is one new challenging task in environmental monitoring where WebGIS can be used for standardised data collection and retrieval as well as for risk assessment support. Up to now only few federal and national environmental monitoring networks meet these requirements (Schröder and Pesch, 2004;Schröder et al, 2002). Although in Germany GMO crops like Bt / HR-maize, in particular, are already cultivated on about 225 crop fields with an acreage of about 3,774 ha (state 3/2007) 1 no GMO monitoring in regard to the EC directive 2001/18/EC has been established, yet.…”

The surveillance of genetically modified organisms (GMO) dispersal is a new challenging task in environmental monitoring. Web-based geoinformation systems (WebGIS) are tools for the harmonisation of monitoring methods, network design and data handling in the framework of GMO-monitoring data. Furthermore, WebGIS can be used for serving report duties, for planning GMO-monitoring or as data base for statistical analyses and dispersal models. We developed a WebGIS GMO Monitoring and integrated site-specific data from appropriate environmental monitoring networks and surface maps allowing for the description of the environment of the monitoring sites in terms of, e.g., land use and climate or altitude above sea level. We used platform independent Open Source-software. The WebGIS considers standards released by the Open Geospatial Consortium (OGC) and the International Organisation for Standardisation (ISO) to ensure interoperability between web mapping services (WMS) located all over the world. Projects like INSPIRE (Infrastructure for Spatial Information in Europe) or PortalU use these standards as well. The WebGIS GMO Monitoring offers tools for visualisation, spatial and logical queries as well as interactive data processing tools.
