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.

Rehabilitation Monitoring

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 a desired area, commodity and requirements.

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

Spectral processing

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 types, but also map hydrothermal clays. 

ASTER sensors are also able to leverage multiple thermal imagery to identify epithermal clay minerals, iron oxides, silica, carbonate, malice and propylitic alteration. This imagery is best used for regional mapping at scales down to 1:50,000.

When combined with the satellite-derived surface elevation models, both these products described can be used in stereo analysis to delineate structural features. A two-fold approach between both products is quite common, with lower resolution SRTM data being commonly used for the initial analysis, and high-resolution elevation data consequently being utilised over the areas that show the potential.

If you’re seeking to explore an area to identify potential minerals, ores or propylitic alterations, our team of satellite imagery experts can help. Call us now on 07 3319 4990 or email us via

As another year comes to an end, we're already busy planning ahead with our clients for 2018 operations.

If you're looking to capitalise on any remaining budgets from 2017, now's the best time to put them to use before it's too late.

We're seeing organisations take advantage of this period to invest in the expansion of their existing satellite imagery collections and geospatial solutions. How can Geoimage help you hit the ground running in 2018?

Get in touch with our team today to discuss options available to make the most of your remaining 2017 budget. Call us now on 07 3319 4990 or email us via

We're closing our doors from 4pm Friday 22nd December! Our office will re-open Monday 8th January 2018.

Geoimage is experiencing very high demand for Digital Elevation Model (DEMs) purchases, with our Mining, Oil and Gas clients opting to use satellite imagery wherever geospatial insights are required. 

Satellite can be considerably less expensive than LiDAR for DEM creation and environmental monitoring. This combined with the benefits of using 8 multispectral bands, DEMs can provide added analytic options for greater insights into your specific project requirements.

Today Geoimage can offer 50cm DEMs with 30cm resolution imagery, from anywhere around the globe, and the capacity to capture will soon double following the commercialisation of DigitalGlobe’s latest high-resolution satellite imagery by WorldView-4.

Geoimage's Geospatial Processing and Technical team specialises in DEMs creation derived from either archived stereo imagery, or can task a satellite to custom collect stereo data specifically over your area of interest. This speed of capture and the amazing accuracies obtained is good news for clients requiring detailed terrain information over any global location.

Some common uses of DEMs include:

  • Extracting terrain parameters
  • Operations management, identifying pit and stockpile changes
  • Calculating topsoil clearance and remediation requirements
  • Modelling water flow or mass movement (for eg. landslides, wall collapses)
  • Orthorectification of aerial photography or satellite imagery
  • Terrain analysis in geomorphology and physical geography
  • Engineering and infrastructure design
  • Line-of-sight analysis
  • Base mapping
  • Hydrological modelling – flood mitigation or watershed analysis
  • Environmental change application
  • Risk assessment.

DEMs can be delivered to you either as a Digital Surface Model – including vegetation, buildings and more, or as a Digital Terrain Model – removing trees and buildings to deliver a “bare earth” model. Multiple DEMs can also be compared to identify changes in volume, for example, stockpiles, tree canopy cover, pit size and clearance, and more.

Digital Elevation Models are an integral part of any geospatial analysis. Some of the benefits of using satellite imagery, include:

  • World wide availability without any access restrictions
  • Large area coverage
  • Resolution from very high to regional
  • Fast processing time
  • Low processing cost

Geoimage are experts in creating all types of DEMs from satellite imagery suited to your specific needs and requirements.
