Novi Sad Green Areas GIS

From Airborne Vegetation Mapping to an Operational Urban-Greenery Platform

Novi Sad Green Areas GIS connects 2.5 cm airborne imagery, vegetation/point-cloud processing, field-verified inventories, Web GIS and mobile operational workflows.

Project context

One system had to begin with physical reality — and end in daily municipal operations

The City of Novi Sad needed a structured information basis for urban green areas that could support planning, maintenance, inspection, reporting and continuous update. The project therefore combined city-scale geospatial production with operational Web and mobile software instead of treating mapping and management as separate tasks.

Airborne acquisition

City-scale capture at 2.5 cm ground resolution

MapSoft planned and carried out the aerial campaign over Novi Sad from 9–13 August 2020 using the SILA 750 aircraft. Final project material records 12,108 images, approximately 5 TB of raw imagery and 2.5 cm GSD.

Multispectral point-cloud processing

RGB + NIR attributes became part of the classification workflow

The processing chain combined point-cloud geometry with RGB and NIR information. RGB/CIR colourization, NDVI calculation and multispectral attributes were used together with geometry to improve separation of urban-scene classes — especially vegetation — before vegetation-only extraction and height-based classification.

The sequence below is built from authentic project stages: RGB → CIR/NIR → all classes → ground + vegetation → vegetation-only → NDVI → NDVI filtering.

Detailed inventory

From city-scale vegetation signal to field-verifiable managed objects

Approximately 500 ha of public green areas were mapped in detail using stereorestitution followed by field verification and supplementation. Low, medium and high vegetation were vectorized into GIS-ready geometry and connected to the operational object model.

Operational Web GIS

The resulting data became a working green-infrastructure platform

The customized MapSoft Geoportal connects green spaces, maintenance units, attributes, statuses and editing workflows in one browser environment. Authorized client users can inspect and maintain the spatial inventory rather than rely on a vendor-only update model.

Vegetation intelligence

Map-based statistics turn the inventory into decision support

The Geoportal provides vegetation analysis and statistics by spatial unit, connecting mapped objects with area-based indicators and visual summaries that support planning and operational review.

Operational workflow

Inventory, planning, field work, inspection and reporting share the same information model

The platform was designed around a complete municipal workflow rather than a map viewer: maintain the inventory, plan work, record execution, update from the field, manage inspection and change, analyse results and administer users and data governance.

Adoption & enablement

A multi-organization system supported by structured training

Final project material documents training for 40 attendees from 9 organizations across administrator, office-user and field/mobile-user roles.
