Stapelfeldt Ingenieurgesellschaft mbH is an environmental impact analysis software and consulting company based in Dortmund, Germany. Its core product, LimA, is designed for modeling environmental noise, air pollution, shadows, and solar radiation. It is not a general-purpose enterprise SaaS product, but specialized engineering software for acoustic consultants, environmental agencies, heavy industry, educational institutions, urban/transport planners, and government bodies.
LimA covers noise prediction for roads, industry, railways, aviation, and wind turbines, and can be extended for air pollution, shadow, and radiation analysis. Its standout capability is large-scale model computation: the website says it can be used for city- and even national-level noise maps, with a tiling mechanism that goes beyond the limits of conventional model sizes. Standards support is extensive, including CNOSSOS, Harmonoise, ISO 9613, BS 5228, DIN 18005, RLS 90, SCHALL 03, and others. For GIS integration, LimA can connect with ArcGIS and QGIS, and uses the LimAQ plugin to leverage QGIS geoprocessing capabilities. It also supports Google/OSM WMS overlays, a 3D Viewer, and KML export.
The website does not disclose specific pricing, licensing models, free editions, or trial information. It only mentions that additional computing resources and flexible plans are available. Deployment options are also not clearly stated; the wording suggests more of a traditional professional software package combined with computing-resource services. On the developer-support side, there is no visible open API, but the site notes that functions can be integrated into batch workflows and that a macro library is available for automating and customizing complex processes.
Its strengths are deep industry experience, a product history of more than 30 years, customers in over 50 countries, strong computational performance, ongoing standards updates, major-project experience, and consulting/support capabilities. The drawbacks are limited commercial transparency: payment methods, trials, security and compliance details, and team-permission features are not disclosed. It also has a relatively high barrier to entry for users without expertise in acoustics or environmental modeling.
LimA is best suited to professional organizations working on urban noise maps, traffic noise assessments, industrial boundary noise, aviation/railway noise, and environmental impact assessments for planning. The available text does not mention access from China, so this remains unknown; payment and local reseller information is also missing. For procurement in China, it would be worth comparing SoundPLAN, CadnaA, Predictor-LimA, ODEN, as well as localized environmental modeling solutions built around ArcGIS/QGIS.
