SELMA GIS

SELMAGIS for ArcGIS 10.3 AUSTAL2000 MEMO and MARS/MUSE, PROKAS OML-Highway

SELMA^GIS is a system for Air Pollution Modelling and Visualization. SELMA^GIS offers a unique graphical user interface to work with different dispersion models. It's based on the Geographical Information System ArcGIS 10.3 or higher and is used as an extension in ArcMap. SELMA^GIS makes it easy to work with different sophisticate dispersion models utilising all advantages from the large functionality of ArcGIS, e.g. getting and preparing input data from large data bases, result evaluation by spatial joining with different theme layers and 3D-visualisation (requires 3D-Analyst extension from ESRI).

Modules in SELMA^GIS

SELMA^GIS includes the following Tools:

• SELMA^Digitizing Tools. For digitising road, area and point emission source and 3-dimensional building information's. All data are stored as data base format Shape (ESRI)
• SELMA^Meteo for importing, visualizing and meteorological information from measured data,
• SELMA^Emission
  • to define time series (variation in the year) and
  • to calculate the exhaust pipe emissions of vehicles, including Pm10 emissions calculation appropriate Düring et.al
• SELMA^Domain for defining the receptor grid (nesting is possible)
• SELMA^Navigator for starting the current model. There are implemented yet AUSTAL2000, PROKAS and OML-Highway.
• SELMA^Results to evaluate result data coming out from different dispersion models. The results of each calculation are visualized directly in ArcMap (*. shp) and saved as EXCEL compatible files (*. dbf). Further processing, for example for comparisons with monitoring data, is possible. Various export formats are supported from ArcGIS, e.g. PDF, JPEG, TIF, Mapinfo, Google Earth (only with ArcGIS 9.3 and higher).

At this time SELMA^GIS includes the following dispersion models:

• AUSTAL2000 for calculating dispersion of various substances from point (stacks), line (Streets), area (dumps), grid (emission inventories) and volume emission sources. AUSTAL2000 includes a 3-dimensional Lagrangian particle model and contains a flow model being able to cope with complex terrain (mountains, hills) and also the effects of buildings. AUSTAL2000 is official German Federal Environmental Agency air pollution dispersion model and meets the demands contained in appendix 3 of the German "Technical Instruction Clean Air" (TA Luft).
• PROKAS is used for calculation of air pollution concentration on roads and road systems. It consists of various modules to calculate traffic induced emissions on roads (PROKAS_E), pollutant dispersion on roads without or with loose developments, as well as dispersion on densely developed roads (street canyons).
• The dipersion model OML-Highway was developed especially for motorways by the Aarhus University, Roskilde in Denmark.
• Additional dispersion moduls will be implemented on demand.

SELMA^GIS is available in English, German and Lithuanian language. The documentation and online help is only available in English language.

Area of Application

SELMA^GIScan be applied in different scales (from mesoscale down to microscale) as well for screening purposes to get first quick estimations on the basis of a reduced set of input data, as for sophisticated applications using high quality data and models.

Reference

The modules of  SELMA^GIS are tested and in practical use in Germany, Austria, Bosnia, Lithuania, Bulgaria, Luxenburg and offices of Ingenieurbüro Lohmeyer GmbH & Co. KG in Karlsruhe and Dresden..
