GIS & Remote Sensing

We turn satellite, aerial and drone imagery into decision-ready maps and analysis. From DEMs and orthophotos for hydro projects to vegetation and land cover studies, our geospatial work supports planning, clearances and monitoring.

Capabilities

Photogrammetry

We extract accurate 3D terrain information from overlapping satellite and aerial imagery. The resulting DEMs, orthophotos and contours give planners a reliable base map long before anyone sets foot on site.

  • Aerial triangulation and bundle block adjustment
  • Orthorectification of satellite and aerial imagery
  • DEM generation and editing
  • Orthophoto and contour generation
  • 3D terrain visualisation

Mapping & Analysis

We classify and analyse imagery to show what is on the ground and how it is changing. Land use, vegetation health and catchment maps support feasibility studies, approvals and monitoring.

  • Land use and land cover (LULC) classification
  • NDVI and other vegetation indices (NDRE, SAVI, GNDVI)
  • Change detection and multi-date analysis
  • Hyperspectral and multispectral image analysis
  • Watershed and catchment mapping
  • Pre- and post-excavation surface and volume estimation

Forest & Wildlife

Projects that touch forest land need clear, defensible maps. We prepare forest clearance documentation and map forest cover and wildlife habitat to support environmental approvals.

  • Forest clearance (FC) maps and documentation
  • Forest cover and density mapping
  • Wildlife corridor and habitat mapping

Drone Services

Drones capture high-resolution data quickly over sites that are large, remote or hard to access. We fly, process and deliver orthomosaics, LiDAR point clouds and vegetation surveys.

  • Drone mapping and orthomosaics
  • Drone LiDAR
  • Vegetation index surveys from multispectral sensors
