Aerial photography is curried out with the Geoscan UAVs supplied with full-frame Sony cameras and dual-frequency Topcon GNSS receivers. Photogrammetric data analysis is conducted in the Agisoft Metashape Professional software.

Around the world, there is a great demand for aerial photography to conduct surveying and acquire data. The reason is:

Low price of aerial photography

Aerial photography costs several times less than satellite imagery and traditional surveying.

High precision

Standard deviation of feature points is less than 10cm.

High resolution of photos

The Geoscan UAVs allow receiving photos with spatial resolution up to 1 cm/pix, which guarantees high level of precision of models and orthophotos.

Work in difficult conditions

Aerial photography can be carried out in low cloud and within wide range of operating temperatures, from -20 to +40 °С. Aerodynamic properties of the Geoscan UAVs allow them not to diverge from a route even in a windy weather.

Work in necessary coordinate system

After a flight you receive georeferenced photos, and while processing the images, you can refer them to a necessary coordinate system.

High productivity

Several hundred square kilometers can be surveyed per a day.

 

Acquired data

Photogrammetric processing, carried out in Agisoft Metashape, allows receiving necessary data for further use.

In one file or tiles. Formats: geotiff, jpg, png, GoogleEarth KML\KMZ.

ResolutionResolution up to 2 cm/pix

ScaleScale from 1:500 to 1:5000

Dense point cloud Dense point cloud
DSM is necessary for surveying terrain in detail on any territory.
DSM analysis allows resolving the following problems:
Mapping

Mapping

On the base of DSM, terrain maps can be built as well as geomorphic features can be researched.

Building design

Building design

DSM allows determining the volume of earthworks and monitoring changes over time.

Road design

Road design

The structure of relief is surveyed, trail profiles are built as well as pit depths, volumes of embankments and directions of excavations are measured.

Environment

Terrain models allow building surfaces with contour lines with the required height relief sections.

Modelling in GIS

Modelling in GIS

Creating DSM for digital maps and navigators.

The Agisoft Metashape software allows building a three-dimensional polygonal model of an object after processing photos as well as creating photorealistic models that can be used for further analysis.
