• The only true UAV photogrammetric mapping system

    DroneMetrex's TopoDrone-100 with georeference

    The TopoDrone-100 is an unmanned aerial mapping system which provides the most accurate solution for rapid and reliable photogrammetric mapping of mines, stockpiles, pipelines, highways, railways, rubbish dumps, agricultural and forestry sites and other areas.

    The TopoDrone-100 is easy to program for autonomous flight paths, with manual over-rides for safety and recovery if required.

  • User benefits

    Provides a fast, safe and cost-effective mapping solution for a wide range of industries, including geospatial, surveying, civil engineering, mining, agriculture, environmental protection, etc.

    Maps large and at the same time difficult-to-access and dangerous areas, such as flooded zones, bushfire areas, deserts
    with low cost incurred,
    within shortest possible time,
    with quick mobilisation
    minimum security or flying clearances.

    It is able to be operated with minimal training. It launches and lands in any terrain and it can fly under clouds and strong winds.

  • Unique feature: Dynamic Stabilised Active Mount (DSAM)


    The TopoDrone-100 features revolutionary Dynamic Stabilised Active Mount (DSAM) which compensates for “aggressive” flight movements, eliminating camera geometry errors during flight and thus removing the need to correct these in post processing data.


    The Dynamic Stabilised Active Mount (DSAM) is designed with an integrated protective door which is closed during launch and landings, and can be activated at any time of the flight sortie.

  • Unique feature: Direct Georeferencing Solution L1/L2/L5/GLONASS/COMPASS(BeiDou-2)


    The TopoDrone-100 is easily upgradable for Direct Georeferencing L1/L2/L5/GLONASS/COMPASS(BeiDou-2) – mapping with no ground control!

    We have developed our Direct Georeferencing Solution which uses L1/L2/L5/GLONASS/COMPASS(BeiDou-2) on board of our TopoDrones, synchronised to the nano-second of the camera shutter. It ensures accurate positioning of each photograph.

    Differential GPS post-processing is then used to obtain the accurate camera positions which are then used in photogrammetric aerial triangulation.


    • mapping larger areas (which may require several flight sorties to cover the full area of mapping)
    • reduction/full elimination of ground survey control points: when ground survey control needs to be reduced to only one or two points or when ground survey control points are not used at all
    • mapping “challenging” terrain: when the terrain to be mapped is more “challenging” for the type of coverage and therefore the pixel matching (such as dense forests, coastal mapping, etc.)


    • dramatic improvement in mapping accuracy
    • significant reduction of processing time
    • highest quality of overall photogrammetric mapping

  • Unique feature: Stereo mapping and 3D “heads-up” digitising

    Stereo mapping and 3D “heads-up” digitising by DroneMetrex

    Our Drone Mapping System provides a unique opportunity for stereo mapping: from the start the imagery can be viewed and digitised in true 3D “heads-up” mode.

  • Output products

     Output products include:  high density point cloud, accurate imagery (digital orthophotos, digital seamless orthophoto mosaic of the whole area), volumes and profiles, Digital Terrain Model (DTM) – Bare Earth, Digital Surface Model (DSM), contours, 3D photogrammetric “heads-up” feature digitising, digitised linework (kerbings, roof tops, GIS assets, etc.), which can be fed into the design and planning process for industrial applications:
