LimAarc integrates the LimA program system for calculation of noise distributions as an Extension into the ArcGIS geographic information system (GIS). With LimAarc all data for noise modelling are supplied and maintained in ArcGIS. The noise model is handled by the GIS and has direct access to the GIS data. The noise modelling software itself is tightly integrated into the user interface of ArcGIS and calculations are carried out from within ArcGIS. Results are automatically converted into GIS data and are directly available in ArcGIS for further analysis, presentation or map production.
