- KonferenzbeitragCitizen-Centred Information Dissemination with Multimodal Information Channels(Sustainability in the Information Society, 2001) Johansen, Per Henrik; Karatzas, Kostas; Lindberg, Jon Eric; Peinel, Gertraud; Rose, ThomasCitizens call for timely and high-quality environmental information for reasons of comfort and health care. This interest recommends an easy-to-understand and easy-toaccess presentation of such information. Rather than presenting raw data in an extensive fashion, one ought to engineer customisable information services, that can be tailored to individual user groups, be it for reasons of content or be it for reasons of citizen's reachability. InAPNEE, we have been designing information services that draw upon various information channels, i.e. mobile-technologies, interactive portals for the Internet, as well as street panels for municipality usage scenarios. In a nutshell, the APNEEsystem promotes user-friendly information management and dissemination via multiple information channels, and can be applied in multiple information domains or be part of relevant applications or service back bones. Based on such high quality dissemination services, even environmental information will turn into an attractive product once perceived and provided as indicators for emerging interests of citizens towards levels of comfort.
- KonferenzbeitragEnvironmental Services and Data Brokerage Portal: ENV-e-CITY in Action(The Information Society and Enlargement of the European Union, 2003) Moussiopoulos, Nicolas; Karatzas, Kostas; Endregard, Geir; Fedra, Kurt; Friedrich, Rainer; Johansen, Per Henrik; Kalognomou, Liana; Karppinen, Ari; Kraggerud, Per Haavard; Kukkonen, Jaakko; Larssen, Steinar; de Leeuw, Frank; Lohmeyer, Achim; Naneris, Chris; Nicklass, Daniel; Papaioannou, Giannis; Peinel, Gertraud; Pulles, Tinus; Reis, Stefan; Rose, Thomas; Sedlmayr, Martin; van den Hout, DickENV-e-CITY is a European Commission supported e-content project that aims to develop an internet-based service for environmental information related applications. The motivation of this project lies in the need of European cities to perform assessments for complying with the EU environmental legislation, as well as the requirement for efficient environmental impact assessments. The e-content domain considered extends over four environmental application areas: air emission, air quality, topography, and meteorology. The application framework includes meta-data structures for these domains, export and import filters, interfaces and typical e-content services. The user community of the platform envisaged consists of city authorities, consultants involved in environmental impact assessment studies as well as citizens desiring valid information on the state of the atmospheric environment. An initial set of electronic information services is currently under development and will be demonstrated on the basis of the various user categories.
- KonferenzbeitragMonitoring the Environment on the Internet with Open Source Software and Open Standards(Informatics for Environmental Protection - Networking Environmental Information, 2005) Johansen, Per Henrik; Bakke Nielsen, Geir Oscar; Thorset, Hans EinarOpen Source software and Open Standards have been gaining in popularity the recent years. We will show how we implemented environmental and agricultural monitoring systems using these tools. Based on technology developed and explored in the APNEE and APNEE-TU projects run under the 5th Fifth Framework Programme of the IST, we present how we managed to glue together software components from several different open source GIS and map initiatives and projects, into full-fledge web-applications. 2 cases will be used as examples; a khlong and river pollution monitoring application installed in Bangkok, Thailand, and an agricultural application for making state-of-the-art maps of farms in Norway, which in the future also will include wild life preservation, cultural inheritance, etc. The first is an example of a traditional web client-server application directly based on the APNEE core components, while the latter is a completely distributed system which only relies on external data sources, i.e. it contains and maintains no data on its own, and thus serves as an example on how Open Standards affords inter-application interaction. Both applications are based on a common core of software components and technology. We have deliberately chosen these specific cases so that the knowledge presented will be as broad as possible - both in the technological and the standardization dimensions.
