Classified 3D Point Cloud
A Point Cloud is generated from aerial imagery using specialized software. These points represent the external surface of various objects and each point are defined by X, Y & Z coordinates in a three-dimensional coordinate system. Points can be classified into various categories like: low-, medium- & high vegetation, ground, buildings and structures.
Point Clouds can be exported to 3D Mesh grids for use in CAD and BIM systems.
Digital Elevation Models
DEM are models that are generated using geo-referenced aerial Imagery analyzed and processed in specialized software. DEM can be classified in 2 categories:
- DSM (Digital Surface Model): Representing an elevation model of the earth / ground surface including objects on it.
- DTM (Digital Terrain Model): Representing an elevation model of the earth / ground surface without any object on.
These models can be exported for use in GIS and terrain modelling software. Alternatively, elevation data known as contour lines can be exported for use in BIM, CAD and GIS software.

GIS Maps
GIS (Geographic Information Systems) is a remarkable tool used for calculations, estimates and reports. We use aerial imagery and data made available to display results in an understandable user-friendly way. Types of GIS maps that can be produced:
- Infrastructure maps
- Land use maps
- Orthophotos
- Orthophotos are traditionally obtained from geo-referenced satellite imagery. These image sets might be a few years old and do not show current conditions of the project area. By using a drone and Image processing software, we can supply a clear and up to date orthophoto of the area.
- Topographical maps

Volumetric Calculations
Volumetric calculations are done making use of geo-referenced aerial imagery by surveying an area with a RPAS. These images are analyzed and processed into a 3D-model using specialized software from where we identify the volumes that needs to be calculated. Results are then calculated in cubic meters (m3) and weight in tons (t) or kilograms (kg). We make use of the known material density of the specific material being surveyed to calculate the weight per cubic meter (m3).
Volumetric Calculations can be done on:
- Stockpiles at farms, mines and quarries.
- Tailings dams at mines
- Open cast pits at mines
- Banks on edge of open cast pits
- Cut and fill areas on construction sites
