Belgrade Air Quality GIS
Environmental measurements, spatial predictors and validated NO2 modelling in one operational GIS workflow.
Belgrade Air Quality GIS integrates city-scale environmental data, validated NO2 prediction models and desktop/Web GIS workflows for scenario analysis and planning-related reporting. Its operational status was reconfirmed with the client in September 2026.
From sparse measurements to city-scale environmental understanding
Belgrade needed one operational environment capable of combining air-quality measurements with terrain, land use, traffic, population, heating sources and urban geometry. The challenge was not to display those datasets separately, but to turn them into a repeatable evidence base for planning-related environmental decisions.
Build the model from the city around the measurement points
The modelling foundation integrated heterogeneous spatial variables that could explain pollutant distribution: traffic load, individual-heating sources, population density, land use, building use, special buildings, terrain and 3D urban geometry. MapSoft normalized these inputs into one controlled GIS/database environment.
Terrain and buildings were part of the analytical environment
The project delivered terrain and prismatic 3D building geometry for desktop and Web visualization, providing spatial context and analytical support rather than a full Digital Twin environment.
Turn measured values and spatial predictors into comparable city-wide surfaces
MapSoft and the University of Belgrade Faculty of Mechanical Engineering jointly developed and evaluated the prediction-model activity group. Validation supported reliable winter and summer NO₂ models, while the available data for other pollutants was insufficient for equally dependable final prediction.
Final prediction focused on NO₂, where the available monitoring data supported reliable seasonal modelling.
The result was a working case process — not a standalone model
For an active planning case, users could define the spatial extent, update planned-state layers, run the air-quality calculation, compare existing and planned conditions, generate cartographic and tabular reports and retain the case documentation for later reference.

One environmental workflow across data maintenance, analysis, 2D/3D Web access and reporting
MapSoft implemented the central data model, customized the desktop GIS workflow, developed the Web GIS/Geoportal and server-side modelling/reporting functions, and connected the environment through documented spatial and application interfaces.
A documented API plus SOAP/WCF and WMS/WFS interfaces support connection with external information systems and spatial services; heterogeneous vector/raster/source datasets were normalized into the central environment.
Validate each model against the available monitoring data
Validation covered the NO₂ models and DTM quantitatively, together with geometric, topological, thematic and database-integrity controls. The same process identified where monitoring data was insufficient for dependable prediction.
Data, models and software delivered as one decision-support environment
The project combined city-scale spatial datasets, validated analytical surfaces, a central database, desktop/Web GIS applications, reporting services, deployment, training and support.
