Save time and money using drone-based contour mapping
Queensland Drones specialises in fast, precise contour mapping of large construction and development sites using drones. Drones offer a much faster, safer and more cost-effective path to construction and development site contour mapping.
Our mapping flights are undertaken at 20-24 megapixel image resolution with a typical ground resolution (GSD) of <2.5 cm per pixel, which is close enough to pick out a marker peg, inspection hatch or drain cover on the ground.
Our construction site contour mapping can use your existing survey marker points and any available local government public survey markers. We can also lay our own Ground Control Points (GCPs) using dual-frequency GNSS satellite technology with correction via the Trimble corrections network to typically <1 cm. Contours can be levelled to your own local datum or to GDA94 with Australian Height Datum (AHD) heights.
Our team can usually be on your site within 3 working days (faster for urgent requests) and have contour data back to you within a few days after that. Data is supplied in PDF, KMZ and DWG file formats for ease of use. We are willing to travel anywhere in Australia or internationally to capture imagery for ortho-mapping. We have our own GIS specialist and our own GIS data processing platforms for fast, reliable map generation.
