Remote Sensing

Remote sensing involves the collection of high-precision geospatial data using LiDAR (Light Detection and Ranging) and photogrammetry from aerial, terrestrial, or mobile platforms. These technologies allow AeroTek to create highly detailed 3D models, terrain maps, and structural assessments without the need for extensive on-site ground surveys.

LiDAR emits laser pulses that measure distances to the ground or objects, generating dense point clouds that can be processed into high-accuracy digital models. Photogrammetry, on the other hand, involves taking multiple high-resolution images from different angles and processing them into accurate 3D reconstructions using advanced software and AI algorithms.

Together, these technologies provide comprehensive spatial intelligence for engineering, construction, environmental monitoring, and asset management. In Guernsey, where coastal topography, dense urban infrastructure, and protected natural landscapes require meticulous surveying with minimal impact, remote sensing allows for fast, non-invasive data collection across large or inaccessible areas.

  • 🔸 Construction & Engineering Firms for high-accuracy site data for planning and design
    🔸 Infrastructure & Utility Companies for monitoring roads, pipelines, and civils
    🔸 Property Developers & Architects for creating realistic 3D models for clients and planning approvals
    🔸 Environmental Agencies & Conservationists for tracking habitat changes and coastal erosion
    🔸 Government & Local Authorities for managing land-use planning and public works projects
    🔸 Agricultural Businesses & Landowners to enhance land productivity through precision mapping

  • These surveys are curated to the client’s requirements, however typical deliverables include:

    ✔ 3D Point Cloud Data (LAS/LAZ Format) – High-density, georeferenced datasets that provide detailed elevation and structure mapping

    ✔ Digital Terrain Models (DTM) & Digital Surface Models (DSM) – Ground-level elevation data (DTM) for topographic studies, and DSM for mapping buildings, vegetation, and infrastructure

    ✔ Georeferenced Orthophotos (Aerial Imagery) – High-resolution, distortion-free aerial images corrected for spatial accuracy, used for urban planning, coastal monitoring, and infrastructure projects

    ✔ 3D Mesh Models & Textured Digital Twins – Photorealistic site visualisations used for construction planning, historic preservation, and urban development

    ✔ Volumetric Analysis & Stockpile Measurements – Accurate calculations of material volumes for earthworks, excavation, and resource inventory management
