Aerial Surveying

Naga Visions offer aerial surveying and data processing services through our Australian partners with cost-effective state-of-the-art systems and extensive experience of international projects.

The acquisition and processing uses technology and methods derived from the aerospace industry, high-end computing science, digital imaging, geospatial analysis and military intelligence.

Data are captured using the following systems:

  • 3 large format cameras (Vexcel UCX, UCXp, UFp)
  • 3 medium format cameras (IGI Digicam H39, H50, H60)
  • 1 oblique system including 4 x Hasselblad 50 MPix camera, with a 45° oblique angle and 150mm lens (10cm GSD at 5000ft)
  • 3 lidars (IGI Litemapper LM5600, LM6800, LM7800)

Together with partners we can also offer realistic 3d Models solutions. Applications:

  • GIS update
  • Orthophoto and DTM creation
  • Utilities, Cadastre, Urban Planning, Asset Management and Environmental Studies
  • Oil and Gas
  • Mining
  • Infrastructure Engineering
  • Topographic Mapping

Small Areas

RPAS (Remote Piloted Aircraft System) technology has become extremely reliable in terms of automatic flight control. High resolution imagery can be acquired from different platforms depending on the requirements.

We focus on the automatic and fast processing of the imagery which provides our clients with a quick turnaround of a couple of days from the capture of the imagery to the delivery of the end products.

Quick mobilisation anywhere in the world with high-tech, compact RPAS (Remote Piloted Aircraft System) hardware and low cost operation is now possible. Typical photographic coverage is up to 0.5 square km at 2cm ground resolution in less than an hour of flight.

The RPAS (Remote Piloted Aircraft System) are electric powered, therefore leaving zero carbon emission footprint, an environmental friendly solution that is also a non-hazardous one if flying over areas where petrol powered RPAS (Remote Piloted Aircraft System) are too risky.

Different sensors are available for mapping or surveillance: High Definition (HD) video cameras, high resolution SLR photogrammetric cameras as well as night vision sensors.

Our RPAS (Remote Piloted Aircraft System) solution is particularly efficient and affordable for:

  • Mapping of open pit mines, oil and gas refineries, harbours…
  • Environmental studies, impact from natural disasters
  • Corridor mapping: pipeline, power lines, railway, roads…
  • Emergency services and law enforcement: accidents, crime scene..

Large Areas

If large areas are to be captured for mapping purposes (more than a thousand, an innovative solution can be proposed with a super large frame digital camera (SLF) for acquiring imagery either in True Colour (TC) or/and False Colour Infrared (FCIR).

The exceptional performance of the VisionMap A3 camera allows to capture 1,000 sq. km in a day at a ground resolution of 10cm taken from about 11,000 feet above the ground.

This very compact aerial survey digital mapping camera is about 10 times lighter than conventional aerial survey large format digital cameras. Its accuracy cannot be disputed neither its advantages:

  • IMU and stabilised mount are not required
  • High resolution imagery can be captured over airports areas
  • Very large sweep offering oblique view
  • High overlap for robust ray matching in the aerial triangulation
  • Twice the productivity vs conventional aerial digital survey cameras
  • Lower carbon emission footprint because of less flying…
  • This revolutionary camera is an excellent tool for covering large areas in minimum time


The Metasensing Synthetic Aperture Radar compact sensor allows accurate mapping measurements derived from L,Ku or X band. It can be installed on small, readily available inexpensive aircraft. The sensor provides a resolution up to the decimeter level with a coverage rate that can reach 600 sq. km per hour. Main applications are digital terrain modeling, environmental monitoring, mapping through vegetation and change detection.

Aerial thermography can help in analysing the heat loss of houses and buildings and therefore optimise the insulation. This technology becomes more and more attractive to government agencies , private sector and individuals seeking to reduce their energy costs.
