"Aerial mapping with a difference"

GeoM offers clients quality data capturing and mapping for the mining and power line industries. With innovative aerial mapping techniques that allows for low flying data capturing, ensuring accurate data capturing with a single flight. GeoM offers volumetric surveys, open cast mine mapping and data management for the mining industry. Ensuring comprehensive mine planning and maintenance during the life cycle of a mine location. GeoM also caters to the power line and tower infrastructure maintenance and management for the Electrical Transmission industry. Ensuring that the topographical data captured with innovative LiDAR mapping documents all the vegetation management needed around the power lines and towers.

Hyper spectral Data – The fusion of Hyper spectral data and LiDAR data makes it possible to characterize plant and forests in terms of species and health, tied to the stand height and structure.

Volumetric Surveys

Specialising in Volumetric Surveys

Volumetric surveys are very useful in a number of quantitative (measurable) ways as well as being a qualitative (visual) representation of a project site in three dimensions. GeoM specialises in volumetric surveys using LiDAR and small format aerial photogrammetry. The small format aerial photogrammetry technology, used for mining, stockpiles, gravel pits and landfill monitoring: is more accurate, quicker and more cost-effective than field surveys. GeoM can also supply high resolution, colour orthophotos in digital, as well as laminated hard copies.

LiDAR

Light Detection and Ranging Systems

Light Detection and Ranging (LiDAR) is an impressive and highly practical technology that uses laser pulses to generate large amounts of data about terrain and landscape features. LiDAR is an important geospatial data acquisition technique, which GeoM utilizes to determine topography and surface information. GeoM uses LiDAR as a part of their quality services to suit specific client requirements.

LiDAR Applications

LiDAR uses laser pulses to generate large amounts of data about the physical layout of terrain and landscape features. LiDAR data can be analysed and used in a range of applications including:

  • Land mapping for use in forestry and land management
  • Digital terrain maps for use in geographic information systems
  • Digital Mapping for use in analysing building structures and architecture

How Does LiDAR Work?

There are several varieties of LiDAR, all of which operate using the same basic principle: the instrument fires rapid pulses of light at the target and a sensor mounted in the survey aircraft measures the amount of time taken for each light pulse to bounce back. GeoM utilise LiDAR along with other techniques to provide accurate and detailed aerial surveying solutions to all clients.
