The lagrangian dispersion model LASAT, developed and distributed by Ingenieurbüro Janicke, is being employed by IVU Umwelt GmbH in addition to IMMISnet to calculate pollutant dispersion. LASAT is a complex model for calculating concentrations of air pollutants, taking into account e. g. orography and building structures. It is based on the same algorithms as AUSTAL2000 and is in accordance with the new German directive on air pollution modelling TA-Luft.
In studies for large areas with many emission sources, the generation of input data in the required formats is often tedious. The use of a GIS for the automatic generation directly out of GIS-data is practically indispensable. Therefore, IVU Umwelt has developed the ArcGIS-Extension LASarc.
The current release LASarc offers the following functionalities:
LASarc is available for ArcGIS.
