We offer software that is constantly in use in our office during the preparation of expert opinions and therefore has a high user comfort and quality standard. This software was partly
- developed by us to improve the quality and efficiency of our internal consulting work, and some of the software was
- commissioned work.
Application areas of the software are
- Calculation of atmospheric flow processes
- Calculation of atmospheric dispersion processes
- Particulate matter forecasts for today and the following day
- Calculation of odorous substance emissions
- Incident information concerning dispersion of pollutants

From SELMAGIS to the Win product range
The Win product range from Lohmeyer offers a modern and integrated software environment for dispersion modelling. All programmes are based on a common GIS platform, which allows input and output data to be captured, edited, checked and clearly visualised in a georeferenced format. Thanks to open standards, in particular the ESRI Shapefile format, data can be reused efficiently within the Win product range and can also be easily imported into QGIS or ArcGIS Pro.
The workflow is clearly structured and consistent across the board: first, emission sources and emission parameters are prepared. The model area and exposure locations are then defined, meteorological input data is compiled, and all information for the respective dispersion model is consolidated. Following the dispersion calculation, the results are evaluated and, where necessary, further processed to determine the total pollution load.
The Win product range bundles these steps into modules that can be used across different models. This ensures a consistent user interface across all programmes, makes it easier to get started with further applications, and consistently carries forward the tried-and-tested SELMAGIS philosophy into a modern stand-alone environment.
The Win product range includes, in particular, the following modules:
- Digitisation for recording and processing emission sources, emission and dispersion parameters, and three-dimensional building information
- Roseplot for importing, processing and displaying meteorological measurement data
- Emissions for generating emission time series and performing calculation of road emissions using PROKAS_E
- Grid-Creator for generating exposure locations, for example as a grid with nesting or as cross-section points along roads
- Navigator for consolidating the required input data and launching the relevant dispersion model
- Results for importing, visualising and further processing calculated concentrations, including the calculation of total pollution loads
The Win product range covers various levels of analysis, from the meso- to the micro-scale. WinPROKAS enables hotspots to be quickly identified at screening quality. With WinMISKAM, high-resolution dispersion calculations can be carried out for such areas, taking buildings into account. WinAUSTAL Pro enables comprehensive dispersion calculations in accordance with TA Luft for emissions from commerce, industry and agriculture. In addition, WinSTACC is available as a system for determining stack heights in accordance with VDI 3781 Part 4.
