On 7 January 2019, DigitalGlobe (a business unit of Maxar Technologies) reported its WorldView-4 satellite experienced a malfunction in its control moment gyros ("CMGs"), preventing the satellite from collecting imagery due to the loss of an axis of stability.

Geoimage (a licensed reseller of DigitalGlobe products) understands efforts are ongoing to restore satellite functionality, however DigitalGlobe believes it is unlikely WorldView-4 will be capable of capturing any further imagery.

Despite this setback the picture is far from doom and gloom. DigitalGlobe operates four state-of-the-art very high resolution satellites, capturing a range of imagery including Panchromatic, 4 band, 8 and 16 band multispectral, and in-track stereo for Digital Elevation Model creation. 

In addition, Geoimage has access to exabytes of historical satellite and remotely sensed data from DigitalGlobe and many other satellite and remote sensing operators. The world in its entirety has been captured literally thousands of times. 

SATELLITE OPTIONS ON THE INCREASE

Geoimage works closely with DigitalGlobe, AIRBUS, 21AT, RESTEC, PLANET and more. Our primary focus is to identify the most suitable remote sensing data solution for clients, create job-ready data sets, and provide a range of expert value-added solutions including Multispectral Analysis, Digital Elevation & 3D Models, Vegetation Analysis, and Change Detection services.

SCHEDULED SATELLITE LAUNCHES – GOOD NEWS FOR ALL

  • DigitalGlobe aims to launch six new very high resolution 30cm satellites named WorldView-Legion in 2021
  • Airbus aims to launch four new very high resolution 30cm satellites, which together will form the Pléiades Neo constellation, on schedule for launch in 2020
  • New microsatellites and remote sensing technologies constantly emerging and evolving.

GEOIMAGE READY TO RESPOND

For more than 30 years Geoimage has invested in state-of-the-art software systems. Our expert staff remain at the forefront of industry capabilities, including satellite borne Synthetic Aperture Radar for surface movement monitoring and operations in areas of poor visibility.

2019 will be a fantastic year for remote sensing. There are many ways to view our beautiful planet. Geoimage is looking forward to working with you and the plethora of current and emerging technology applications in the ever-expanding world of remote sensing.

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 sales@geoimage.com.au.
