- KonferenzbeitragEnviroMap Austria — A Novel Web-Based Environmental Atlas(The Information Society and Enlargement of the European Union, 2003) Orthofer, Rudolf; Kutschera, Peter; Humer, Heinrich; Loibl, WolfgangThe authors propose a new approach for public dissemination of digital map data through an interactive web-based system. Holders of environmental data can publish a version of their data and data seekers get access to these data. Environmental maps are managed as raster data streams based on a standard map projection and a predefined 250x250 m cell size. The advantages of the EnviroMap system are that users do not need GIS expertise, and that data holders can use the system for publishing an "EnviroMap raster version" of their original GIS data and thus advertising the availability of original data. Die Autoren schlagen einen neuen Ansatz für die öffentliche Verbreitung digitaler Landkarten durch ein web-basiertes interaktives System vor. Dateninhaber können ihre Daten mit einem Upload-Tool in das System hochladen, Datennutzer haben dann Zugriff zu diesen Daten. Im EnviroMap-System werden Umweltkarten als Rasterdaten verarbeitet, die auf einer standardisierten Geo-Projektion und einer vorgegebenen 250x250 m Zellgröße basieren. Vorteil des EnviroMap-Systems ist, dass es auch von Nutzern, die keine besonderen GIS-Kenntnisse haben, einfach verwendet werden kann, sowie, dass Dateninhaber eine "EnviroMap Raster-Version" ihrer originalen GIS-Daten veröffentlichen können und damit die Verfügbarkeit ihrer Originaldaten bewerben können.
- KonferenzbeitragMulti-Actor Urban Energy Planning Support: Building refurbishment & Building-integrated Solar PV(Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Ouhajjou, Najd; Loibl, Wolfgang; Fenz, Stefan; Tjoa, A MinConsidering the large amount of energy consumption in cities, two-thirds of the overall consumption, these latter have an important potential in terms of CO2 emissions reduction. Therefore, energy strategies are needed at a city level and consequently, adequate planning tools are required to support urban energy planners in assessing their decisions (e.g. which buildings are the best to refurbish). This paper presents an ontology based approach for urban energy planning support applied to building refurbishment and building-integrated solar PV planning. The adopted methodology is an iterative, incremental process, where each iteration leads to the integration of a new planning decision. The process starts by the identification of the actors whose interests are affected by the decision, then developing/ re-using computation models that provide answers for their questions. The different models are integrated using an ontology that models the parts of the city within the scope of the questions to be answered. The system is applied in a district (about 1200 buildings) in the city of Vienna. The adopted approach provides different actors with specific information to their points of view. Furthermore, the output is aggregated to a common level of abstraction, to be understood by all the actors. This approach is applicable to different cities, as the ontology also integrates extension and upgrade mechanisms that provide flexibility to cope with different data-availability contexts.
- KonferenzbeitragUsing TaToo services to enhance information retrieval about climate change consequences – Demonstration of the Climate Twins scenario(Innovations in Sharing Environmental Observations and Information, 2011) Peters-Anders, Jan; Lobo, Tomás Pariente; Ungar, Joachim; Loibl, WolfgangTaToo’s Validation Scenario (VS) 1 “Climate Twins” is a web application that tries to bridge the gap between scientific climate change model outputs and the scientists’ problem of transporting climate change implications to a broader public audience. To allow “real world insights” about future climate impact and appropriate adaptation, one can look at model regions, where the current climate appears similar to an expected future climate of a point of interest (POI). We call such region pairs with similar climate conditions (at different times) “Climate Twins”. From these (remote) current Climate Twin region parts one can learn “hands on” how future climate impacts may be experienced in the POI and how to adapt there to the changing climate conditions, expected in the future. In contrast to the other two TaToo VS Climate Twins is unique in the way it is making use of TaToo’s services, i.e. its way of using TaToo as a lookup facility to find additional information on a specific topic. The aim of this paper is the description of the Climate Twins application, the lookup process of additional information as well as Climate Twins’ momentary ontology concept.
