Our UAV platforms provide high definition imagery, which can be post-processed to derive digital surface models, all of which enable better scoping, planning, data gathering, design and maintenance decisions.
We are able to deliver data to clients' specifications for in-house processing, or alternatively can offer processing solutions. These include:
Our UAVs acquire multiple vertical images on each flight which once processed, produce high-resolution orthophotos (an aerial photograph with a uniform scale similar to a map). The orthophotos can be geo-referenced to a known coordinate system and overlaid on existing data sets. Imagery can be supplied in formats compatible with most software.
The aerial photography is supplied at resolutions up to <1cm/pixel. This is in high contrast to off-the-shelf aerial imagery which is typically ~10 cm/pixel resolution and may be out-of-date, or satellite imagery which is only commercially available at 40 cm/pixel, and is generally not available "on demand".
As part of our complete service, GUS is able to supply GPS positioning and control surveys to establish a ground control network used to rectify the aerial photographs.
Digital Surface Models
Further processing of stereo images acquired on each flight, allows accurate and detailed digital surface model (DSM) generation. The DSM can be used for visualisation, and allows volumetric analysis (e.g. mine stockpiles) or detailed design studies.
Vertical Take-off and Landing UAVs, with gyro-stabilised pan-tilt capability can utilised to acquire 180° or 360° panoramic images (after processing) which are ideal for scoping, site overviews, construction progress updates and marketing purposes. The precise on board GPS capability of the UAV allows it to return to precise locations to acquire images for repeat “time-series” imagery.
