- Konferenzbeitragemikat.at – Management and Visualization of Spatially Resolved Emission Inventories and Emission Scenarios(Managing Environmental Knowledge, 2006) Orthofer, Rudolf; Humer, HeinrichEmission inventories require the management, documentation and interrelation of large amount of heterogeneous data in a user-controlled logic. emikat.at is a system that supports those who establish emission inventories and work with it. emikat.at consists of a data administration server and a user interface residing on the users’ PC’s (client). At the server database all data is administered specifically for different clients and different versions. Access is limited to authorized clients and their users. Through the user interface, users have the possibility to add, edit and delete data as wells as to define alternate scenarios and to calculate model results. emikat.at derives emissions for the smallest available administrative units, i.e. „census tracts“. In each census tract, emissions are calculated according to the specific properties of emission sources, organized according to business sectors (NACE-system), emission source categories (SNAP-system), as well as according to input materials, fuel types and transformation processes. Emissions from line sources (road traffic) are directly associated to the major roads of a census tract. Emissions can also be calculated on the basis of a 100x100 m raster grid; in that case, land use within a census tract is considered for the spatial allocation of emissions. Results that have a defined spatial reference (such as census tracts, communities, counties, raster cells) can also be visualized as maps. The system was applied to calculate the emissions for the reference year 2003 for the city of Vienna along with two „what-if“-scenarios of this reference year. This paper includes a few illustrative results from the Vienna case study.
- 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.
