Geospatial Service

CREST can now offer support for a range of remote sensing and surveying projects.

Our Spectra SP60 GNSS rover can provide <4cm survey accuracy in real time using Trimble’s CentrePoint RTX correction service, while our Spectra T35 robotic total station can enable surveying with millimetre accuracy.

Our range of drones and sensors can fulfil a wide range of applications:

  • Our small and versatile DJI Mavic Pro can easily be transported and deployed in remote or inaccessible areas to provide high quality video or still images, suitable for creation of georectified orthophotos.
  • Our DJI Inspire 2 takes this a step further with longer flight time and a range of sensors including a Zenmuse X7 camera, capable of recording film quality video or 24 MP still images – allowing for centimetre resolution aerial photography – and a Zenmuse XT radiometric thermal sensor, providing thermal imaging suitable for applications such as energy efficiency and water quality among others.
  • Finally our DJI Matric M600 Pro offers flight times of up to 37 minutes, allowing for extensive coverage in a single flight, and can carry a payload of 6-7kg, allowing for a wider range of sensors to be deployed. This includes our Parrot Sequoia multispectral sensor capable or capturing images in near-infrared (NIR), red-edge, red and green bands, making it ideal for agricultural and biodiversity applications.

Combined with our surveying capabilities, this provides the potential to generate very high resolution georeferenced aerial photography across visible, thermal and near-infrared bands, as well as the generation of scaled 3D models of sites and objects using structure from motion (SfM) techniques.
