Precision Geospatial
Services
From raw spatial data to intelligent 2D/3D deliverables — our core processing services form a complete geospatial ecosystem.
Photogrammetry
Airowtek's photogrammetry service transforms overlapping photographs into precise, survey-grade 2D maps and 3D models. Leveraging advanced SfM (Structure-from-Motion) algorithms and 3D stereo compilation, we process provided imagery to produce dense point clouds, digital surface models (DSMs), digital terrain models (DTMs), and textured 3D meshes.
Our processing workflows achieve high absolute accuracy, ensuring that deliverables are immediately usable in engineering and planning workflows.
- Topographic mapping for roads, railways, and corridors
- Precision 3D stereo compilation for feature extraction
- Volumetric calculations for stockpiles and earthworks
- Site planning and cut/fill analysis
- Floodplain and drainage modeling
LiDAR Processing
Light Detection and Ranging (LiDAR) provides the highest-density 3D point cloud data available in the geospatial industry. Airowtek processes both airborne and terrestrial LiDAR datasets, handling millions of points from raw point cloud data.
Unlike photogrammetry, LiDAR penetrates vegetation canopy to reveal bare-earth terrain beneath forest cover — a critical advantage for corridor mapping, forestry, and archaeological surveys.
- Bare-earth terrain modelling under dense vegetation
- Transmission line corridor and clearance mapping
- Tunnel and underground infrastructure processing
- As-built measurement of complex structures
- Floodplain modelling and hydrological analysis
Orthophoto
An orthophoto is a geometrically corrected image where all perspective distortions have been removed — making it a true map, not just a picture. Airowtek produces high-resolution orthophotos with precise ground sampling distances (GSD).
Our orthophotos are delivered as geo-referenced GeoTIFF files, fully compatible with GIS platforms (ArcGIS, QGIS, AutoCAD Map) and ready for area measurements, digitization, and change analysis.
- Base maps for urban and rural planning
- Asset inventory and condition surveys
- Land use / land cover classification
- Road and utility corridor documentation
- Pre/post disaster assessment mapping
CAD / GIS
Airowtek's CAD and GIS services bridge the gap between raw geospatial data and engineering-grade deliverables. We produce precision 2D CAD drawings, topographic maps, and fully attributed GIS datasets from raw spatial and LiDAR point cloud data using industry-standard software including AutoCAD Civil 3D, ArcGIS Pro, and QGIS.
Our GIS deliverables include spatially referenced vector and raster layers, complete with metadata conforming to IS:4408 and OGC standards, ensuring seamless integration into any planning or engineering platform.
- Engineering survey drawings for project design
- Cadastral and boundary mapping
- Utility network GIS databases
- Spatial analysis and zoning studies
- Change detection and land monitoring
BIM Integration
Building Information Modelling (BIM) represents the fusion of physical reality with intelligent digital twins. Airowtek creates as-built BIM models directly from raw survey datasets and LiDAR point clouds, producing Revit-compatible IFC models at LOD 300 to LOD 400.
Our Scan-to-BIM workflow enables rapid and accurate as-built documentation for existing structures, bridges, industrial plants, and infrastructure assets — eliminating the inaccuracies of manual measurement.
- As-built documentation for existing buildings and bridges
- Clash detection in MEP system design
- Heritage and cultural asset digital preservation
- Facilities management and lifecycle BIM
- Infrastructure project management and handover
Mobile Mapping
Acquire survey-grade spatial data quickly and efficiently from moving platforms. Mobile mapping combines 360-degree panoramic imagery with high-density laser scanning to capture vast infrastructure networks without disrupting traffic or operations.
Our mobile mapping workflows extract critical features such as road topography, signage, power lines, and right-of-way assets, delivering complete city-scale 3D models and GIS databases.
- Road and highway network condition surveys
- City-wide street asset and utility inventories
- Powerline and telecom infrastructure mapping
- Digital twins for smart city initiatives
