Surveying

Our relatively small and easy to operate aerial platforms can be transported easily and used to capture imagery of small specific areas that would be uneconomical or impractical to cover with a traditional manned surveying. 


Instantly, these outputs can be used for a variety of applications including;


  •  Visual analysis of a project and its assets.     
  • Monitoring progress of earthworks and construction projects.
  •  Accurate 3D and 2D measurements like stockpile volumes.
  • Environmental monitoring.
  • Topographic situation for drainage and flood modelling.

All of this information is directly compatible with most survey and engineering software providing a complete and visually detailed data set to integrate into a project’s workflow. 


Aerial images are then quickly processed and transformed into meaningful outputs such as high resolution, orthorectified images and accurate 3D surfaces models. 

Data outputs

Orthomosaic

 What is an orthomosaic photo? ... Unlike an uncorrected aerial photograph, an orthophotograph can be used to measure true distances, because it is an accurate representation of the Earth's surface, having been adjusted for topographic relief,[1] lens distortion, and camera tilt. 

Multispectral

 A multispectral image is one that captures image data within specific wavelength ranges across the electromagnetic spectrum. The wavelengths may be separated by filters or by the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range, i.e. infrared and ultra-violet. Spectral imaging can allow extraction of additional information the human eye fails to capture with its receptors for red, green and blue. It was originally developed for space-based imaging, and has also found use in document and painting analysis. 

3D Point Cloud

 A Point Cloud is a 3D visualization made up of thousands or even millions of georeferenced points. Point clouds provide high-resolution data without the distortion sometimes present in 3D mesh models and are commonly used in industry-standard software. 

Digital surface model (DSM)

 DSM's measure the height values of the first surface on the ground. This includes terrain features, buildings, vegetation and power lines etc. DSM's therefore provide a topographic model of the earth's surface. DSM's can be used to create 3D fly-throughs, support location-based systems and augmented simulated environments. 

3D Mesh with texture

 Texture mapping is a method for defining high frequency detail, surface texture, or colour information on a computer-generated graphic or 3D model. ...Texture mapping originally referred to a method (now more accurately called diffuse mapping) that simply wrapped and mapped pixels from a texture to a 3D surface.
