Noise modelling in GIS
LimA is a joint development of IVU Umwelt and StapelfeldtIngenieurgesellschaft. LimA integrates the LimA Program-System for calculation of noise distributions into the ArcGISgeographic information system (GIS) from ESRI.

Models for calculation of environmental noise are getting moreand more complex and the requirements for the range and degreeof detail of noise rating studies increase. Range and quality ofdigital geo-data for GIS-Systems are growing simultaneously.These trends of development require new arrangements for
programming and data-handling of environmental models. WithArcGIS, ESRI offers a modern, scalable GIS, that can integratemodels and create, data forenvironmental projects effectively and comfortably. Within LimAall data for noise modelling are supplied and maintained
. The noise model is handled by the GIS and has directaccess to the GIS data.

3D-Data
Results in the GIS
With LimA , LimA is embedded in the GIS so you can perform yournoise calculations with LimA directly from ArcGIS. Your geo-data(Geodatabase Shape, ...) are directly available for calculations.There is no need to export the data for calculation purposes, and onlyone non-redundant setof data remains forfurther processing.Powerful ArcGIS toolsfor completing, editing,correcting, and adjust-ing data are available.You may determine theparameters and startthe calculations directlywithin the GIS. Resultsare accessible as sets of data and can be used by ArcGIS immedi-ately: e. g. for generation of maps or further processing like mergingwith other geo-data.

Project ParametersIn the parameters dialogue, the relevant calculation parameters areset interactively with the GIS. You may define the area of calculationby any existing set of data. Additionally, the currently displayed areacan be used or an areadef ined manual ly.LimA-objects in thesets of data are reco-gnized automaticallyand provided with thecorresponding LimA-labels. Further specificparameters needed forthe noise calculationare de-fined by LimAsub-dialogs.
3D-Façades
Noise calculation is started from within the GIS via the LimA Server-Concept. The calculation core works independently from the GIS,allowing you to useArcGIS for any otherpurposes dur ingcalculation. A pro-gressbar displaysinformation about the
and allows for thecancellation of theoperation.

The calculation results are converted into GIS-data automaticallyand are available as raster data in the GRID-format*. InArcGIS thesedata are directly applicable and may be linked to other existing datafor further analyses. All powerful display options of ArcGIS areavailable. In combination with

The LimA-object definitions areavailable in the GIS. So LimA-objectsare recognised automatically, andexplanatory information about theLimA object attributes can also bedisplayed. Via the ‘AttribInfo’
in the context-menu of acolumn oft h e a t t r i -bute-table, ad ia log-boxdisplays the LimA-informations of thechosen attribute.
command
Noise calculations can easily beperformed by for anyreceiver point. Just select thecommand “Calculate receptors” inthe context menu of a point-layer.Calculations are then carried outfor the whole set of data or anexisting selection. The results areinserted into the attribute-table of
the point layer immediately, andthus are accessible in the GIS forfurther handling. By moving oradding points, it’s easy and fast tocalculate the noise level at anysingle point.

Noise Calculation with LimA under ArcGIS®
For detailed analyses, charges of fa ade elements can be determin-ed by LimA. These can be used directly in the GIS and thus by thepowerful 3-D tool of ArcGIS. Also combinations of views of cities (seea b o v e )and in -tegrateddisplaysof fa a-des arepossible.

ArcGIS’ powerful 3DAnalyst visualisation tool lets you display 3-dimensional data easily and quickly. So, effective plausibility checksof the data are possible, and results can be presented impressively.
