The use of RPAS (UAV’s) for image collection with regards to planning and management of infrastructure, safety, production and rehabilitation as well as wetland health assessment, is at the forefront of the Mining and Engineering sectors. Zeemab Holdings is a fully licensed* and insured service provider offering comprehensive georeferenced imagery collection, including but not limited to 3D point clouds, orthomosaics, maps and models. The processed results can also be used for volumetric determination, as well as measurements for various applications such as pit or structural features and technical drawings.
Wetland health assessment and management is a crucial part of environmentally responsible mining practices. The results from the data collected can also be used for wetland and environmental planning and management.

In cartography, a contour line (often just called a “contour”) joins points of equal elevation (height) above a given level, such as mean sea level. A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
An Orthomosaic generation is the automated process for Orthorectifing the raw imagery and mosaicing them into one single image.
This process will generate a Georeferenced Image and optionally a Digital surface model in various different formats.
DTM Digital Terrain Model
A DTM is synonymous with a DEM (Digital Elevation Model). This means that a DTM is simply an elevation surface representing the bare earth referenced to a common vertical datum.
