GIS (Geographic Information System)

Geographic Information Systems (GIS) are a powerful tool for capturing, managing, analysing and understanding spatial distribution, connectivity and interaction of features. Computer-based GIS are used to digitally represent and analyse the geographic features present on the Earth’s surface and the events taking place on it.

GWP Consultants LLP offers a range of GIS solutions, using ArcGIS, for environmental, geotechnical and engineering, hydrogeological, hydrological and surveying tasks. The multi-disciplinary nature of GIS enables GWP to integrate and analyse complex spatial information across multiple disciplines.



In house expertise and services include:

  • A range of remote sensing products, e.g., Landsat, SRTM, ASTER, aerial imagery/photogrammetry, and LiDAR datasets.
  • GIS-based geomorphological modelling. This includes computation of digital elevation, slope, aspect, and application to soil erosion potential, landslide risks, and models to characterise topography, fluvial and coastal geomorphological environments.
  • GIS-based hydrological modelling. This includes the computation of surface water flow direction, flow accumulation, storm runoff routing networks, stream orders, catchment boundary delineation, fluvial and pluvial flooding and coastal storm surge and tsunami inundation modelling.
  • GIS-based image processing techniques for land-use classification.
  • Development of data inputs and visualisation of output results from, hydrological and hydrogeological modelling software packages (e.g. HEC-RAS, HEC-HMS, and Groundwater Vistas).
  • Preparation of datasets for Computer Aided Design programs, including CAD and LSS.
  • Optimisation of development location selection using spatial relationship proximity analysis, including buffer zones, access and transport routes, and hazard zone avoidance.
  • Spatial planning and awareness of the interaction between natural and processes, populations and infrastructure – including disaster risk reduction planning.
  • GIS database management and administration.
  • Cartography and map production.

Recording of a presentation given by Marc Girona-Mata of GWP Consultants at Esri in June 2018.

Due to accelerating climatic and environmental changes, flood hazard modelling and mapping is an increasingly important issue. Flood hazard mapping in developing nations is often restricted to few areas and rarely available for national-scale infrastructure risk analysis and spatial planning, as traditional modelling approaches are inherently affected by increasing uncertainties and require a large number of datasets.
Learn how GWP Consultants overcame this difficulty using a simple GIS-based geomorphological approach, using Samoa as a case study. LiDAR-derived high-resolution Digital Elevation Models and ArcGIS analysis techniques were used to model and map flood hazards. Hear how Collector was used to assist with field activities (validating GIS-based flood hazard products and producing a drainage infrastructure database), significantly reducing time inputs.
ArcGIS Online platform capabilities were used to deliver flood hazard products and improve risk communication to relevant stakeholders, including the Government of Samoa, World Bank, and United Nations Development Programme.
