About This Service

Inundation modelling, risk zoning, and drainage analysis Using SAR (Sentinel-1) time-series, DEM-based hydrological modelling, and field validation, we delineate floodplain extents, model inundation scenarios at varying return periods, and produce decision-ready risk maps for urban planners, insurance underwriters, NEMA, and infrastructure developers.

Inundation modelling, risk zoning, and drainage analysis

Using SAR (Sentinel-1) time-series, DEM-based hydrological modelling, and field validation, we delineate floodplain extents, model inundation scenarios at varying return periods, and produce decision-ready risk maps for urban planners, insurance underwriters, NEMA, and infrastructure developers.

Key features

  • SAR-derived flood extent mapping
  • Watershed & catchment delineation
  • 1-in-10, 50 & 100-yr flood modelling
  • Exposed asset & population analysis
  • Drainage network & culvert mapping

Our Process

Requirement Scoping

We define your project area of interest, desired outputs, required accuracy, and data constraints through structured consultation.

Data Acquisition

We source or capture the optimal imagery or field data — satellite, UAV, or ground survey — matched to your resolution and temporal requirements.

Processing & Analysis

Radiometric correction, classification, feature extraction, and spatial analysis are performed using industry-standard GIS and RS software.

Quality Assurance

Accuracy assessments, error matrices, and field validation are conducted to ensure deliverables meet defined accuracy thresholds.

Delivery & Handover

We deliver print-ready maps, spatial datasets (Shapefile, GeoTIFF, KML), and technical reports with full metadata documentation.
