Airborne Mapping

i) Elevation Updates using IFSAR Technology by Intermap

  • Cloud-free and multi-look radar imagery, to create a unified, seamless, homogenous 3D elevation Digital Elevation Model (DEM) for nationwide.
  • Interferometric SAR is a technique which uses the relative phase difference between two coherent SAR images, obtained by two antennae separated by an across track baseline, to derive an estimate of the surface height.
  • Acquisition 60 times more efficient; 4,000 to 5,000 square kilometers per day.
  • We recently flew over 500,000 square kilometers of Malaysia: 2008 & 2009 data acquisition program (NexMap 05 Product), 2017 data acquisition program (NextMap 05 Product), 2019 data acquisition program (NextMap 05 Product) dan the latest 2022 data acquisition program (NextMap 01 Product).

  • Our personnel are trained and experienced in every step of the process from requirement assessment, GCP establishment, calibration, data acquisition, raw data processing, data post-processing, accuracy assessment, hydrologic-flattening and by product generation.

    • iii) Mobile Mapping Systems (MMS) with Leica Pegasus Ultimate (P2U)

  • Combination of navigation and remote sensing technology on a moving platform, MMS offers the fast, efficient dan complete data collection objects by millions of points per second with centimeter accuracy.
  • Suitable to identify roadway assets and related infrastructure
  • Our MMS product includes:
    o High-resolution 360 Panoramic Imagery
    o Colour-coded LiDAR Point Cloud
    o Features & Assets Extraction
    o Networks Extraction
    o Digital Surface Model (DSM) Generation
    o Digital Terrain Model (DTM) Generation

    • iv) Terrestrial Mobile Mapping with Leica BLK2GO

  • A 3D digital twin creation.
  • Never before has reality capture been so fast, agile and flexible.
  • Capturing Reality is now possible within just a few minutes with Leica’s seamless end-to-end solutions.
  • Can go from field to finish in record time.
  • The BLK2GO handheld imaging laser scanner recreates spaces in 3D as you move.
  • It captures images and dimensionally accurate point clouds in real-time and uses SLAM technology to record your trajectory through space.
  • Applications:
    o 3D Measurements
    o Visualizations
    o 2D CAD Drawings (Floor plans)
    o 3D BIM/CAD Models
    o Construction Verification
