Environmental reporting & rehabilitation monitoring
By leveraging the latest cutting-edge satellite imagery technology, Geoimage works closely with mining organisations to assist in providing environmental reporting and rehabilitation monitoring. Our ongoing partnerships help streamline reporting processes for our clients within the mining industry. Find out below how your organisation can benefit.
Environmental Monitoring and Compliance
As mine sites continue to develop, monitoring both the natural environment and culturally sensitive localities is a key responsibility for all resource operations.
Quantifying and controlling these changes during construction and operation phases is often essential due to legislative reporting requirements. Accurate monitoring and reporting can also save time and money throughout subsequent rehabilitation stages. Using regularly captured imagery, Geoimage works closely with mining organisations to quantitatively track changes in natural (vegetation, fluvial, marine) and pre-existing man-made features. Geoimage can also assist with classifying overburden soil types from satellite imagery, and reporting on total areas covered by a given class.
Site restoration returns disturbed land from mining activities to a stable, productive and sustainable state for both the local wildlife and surrounding communities. During the rehabilitation process, continual evidence-based monitoring and assessments are required to comply with government legislation for all mining leases.
Satellite-derived spatial datasets assist in identifying and quantifying rehabilitation areas, regions of success and stress, and be used to assess change throughout project areas. Summaries of these compliance monitoring activities can then be combined with the evidence and support the completion of mining and rehabilitation compliance reports in a timely manner.
Geoimage arranges satellite capture programs at various resolutions of a project area, on a high-frequency basis. Comparison of multi-date data can assist in identification of any landscape disturbances. Using sophisticated classification algorithms, spectral indices are analysed to identify where mine site pollution, including dust, has impacted a landscape. It is also possible to generate products which assess vegetation health and indicate stress, whether it be development associated or due to natural processes.

Know where to look before you hit the ground
For thirty years, Geoimage has provided services to resource exploration companies through many of the key stages, covering both regional and targeted site selection.
Our cutting-edge satellite imagery offers up to an astonishing 30cm resolution for detailed images over priority areas. Stereo capability delivers Digital Terrain Models with better accuracy than LiDAR of the same resolution, often at a much lower cost.
A cost-effective approach
Initial Regional Analysis and Area Selection
The processes of area selection and target identification can significantly benefit from the use of satellite imagery. With a large archive and relatively low entry price, medium resolution satellite data can be used along with spectral processing derivatives to locate smaller areas of interest.
Once these areas of particular interest have been defined, clients can subsequently task these areas to be captured by the higher resolution satellites. This two-stage approach reduces overall costs by mitigating multiple data capture missions through the use of appropriately scaled datasets.
By identifying structural features, alteration signatures and more, we’re able to highlight ore bodies and their respective mineralisations. Having worked closely with the exploration sector for many years, Geoimage can recommend particular sensors and techniques to aid in exploration depending on
We offer spectral processing suites of both high-resolution SWIR’s from WorldView-3, and the eve SWIR’s from ASTER. Our DEMs can also assist with delineating structure features, and we are now able to produce a 50cm DEM with 30cm contours!
The best ways to uncover a wealth of insights
The Landsat Enhanced Thematic Mapper Plus (ETM+) sensors measure wavelengths that are useful for identifying alterations associated with minerals. As Landsat ETM+ includes a shortwave infrared band from 2.08-2.35mm, it can not only determine rock
ASTER sensors are also able to leverage multiple thermal
When combined with the satellite-derived surface elevation models, both these products described can be used in
