It is with great interest that Geoimage is following progress made by the Church of England (CoE) and the Swedish National Pension Funds (Council on Ethics) (SNPF) via their Investor Mining and Tailings Safety Initiative.  Through this initiative they have highlighted the need for greater transparency of mining activities and potential risks, particularly tailings dam operations.

It’s been reported by AFR (Matthew Stevens 11 June 2019) that the CoE observes: “There is currently no consolidated register of TSF (Tailings Storage Facilities).  It has been estimated that there are approximately 18000 TSF worldwide, of which approximately 3500 are currently active.  However, without a global register, the precise scale of the risks is not clear, nor is it clear which company has responsibility for which facilities.”

Industry is investing with renewed vigour in the design, construction and monitoring methods of TSF and the risks they present to the environment and local communities. There are many ways to monitor TSF and each organisation will have its own approach based on a multitude of factors. “Boots on ground” approaches using traditional survey methods have been supplemented with sensor systems such as piezometers to measure real-time variations in pore pressure.  All of this can be further enhanced with remote sensing InSAR* data that provides highly accurate and independent monitoring from space.

*InSAR (Interferometric Synthetic Aperture Radar), is a method that can measure small changes in vertical movement (7mm) from satellite sensors orbiting the Earth at 600km above the ground.

Two ways JBgeoimage are assisting clients to manage their TSF

SMM (Surface Movement Monitoring) Using InSAR

For more than 30 years Geoimage has been serving the mining and exploration sector.  For the past few years Geoimage has joined with Jensen Bowers (professional surveying business of 110 years) to create the combined resources of JBgeoimage - Applied Spatial Intelligence.  JBgeoimage’s commitment to spatial industry leadership has seen it invest in InSAR.  We are now providing a service referred to as SMM (Surface Movement Monitoring) that uses InSAR.

JBgeoimage has been involved in early Australian trials with leading organisations for both mining applications (tailing dam walls) and linear infrastructure (motorways).  Globally it is well tested and verified technology and it provides an accurate and totally independent movement detection system.  Some of the many benefits are outlined in our linked 2-page flyer on SMM (Surface Movement Monitoring) services HERE

JBgeoimage will soon be making a series of announcements about its innovative and timely atlasTSF interactive dashboard and supporting database for monitoring and analysing TSF around the world.

Here’s a sneak preview of the atlasTSF dashboard with dynamic filters;

1 – TSF filtered on the ANGOLD Hazard rating

2 – filter on company name

3 – filter on TSF Status - active

4 - interactive graph on TSF initial date of operation

5 – filter on Hazard Classification System

6 – 30cm resolution imagery of TSF captured from satellite

7 – tabular information on company and TSF status within a geographically cluster.

Improved Analytics - Higher Resolution SWIR

See beyond what’s visible to the naked eye with short-wave infrared (SWIR) imagery. The WorldView-3 satellite's SWIR sensor goes deeper into the infrared spectrum to help remote sensing experts unlock critical information through advanced analytic capabilities. Eight bands of short-wave infrared imagery previously only available at 7.5m pixel resolution, now available at 3.7m resolution, create rich data for categorizing man-made and natural material, penetrating smoke, detecting fire, mapping minerals and more.

For Geoimage clients in exploration, this improves the Geoimage WorldView-3 Spectral Suite. The high resolution pixel allows for less ‘mixing’ and a more defined signature - helping clients narrow down likely ore bodies and areas of interest.

There are a number of industries that would benefit from using SWIR data, particularly those businesses that would benefit from object identifications or objective analysis. For example: 

• Farmers looking to increase yields whilst decreasing costs and minimising the environmental impact with precision agriculture and farming practices.

• Insurance companies and loss adjusters who need to identify, detect or verify the existence or condition of assets.

• Local governments can utilise SWIR in identifying different land cover types and for emergency management planning.

The below provides an indication of what's previously been captured over Australia. If you're overseas, or your area isn't highlighted below, contact us and we can let you know whether there is archive data available in your area, or how soon we can task new data for you.

Only four weeks into 2019, and it’s already shaping up to be a big year.

We’re delighted to welcome back Greg Madden. Greg brings a wealth of expertise in satellite imagery processing and in the use of RADAR data. He has over 20 years’ experience in the industry with a background in the Australian Air Force as a Geospatial Imagery Intelligence Analyst.

Alongside Greg, Geoimage has a strong team of image processers including Michael Izatt and Rohan Chopra. Both Michael and Rohan have expertise in software coding and are developing solutions that leverage satellite data through integration with other spatial and non-spatial data sets.

Enterprise Solutions Manager, Mark Covington, is spearheading a new wave of service offerings leveraging high-end processing hardware and innovative visualisation tools to solve a wide range of business challenges.

One of the areas of focus in 2019 will be on the use of RADAR for infrastructure monitoring, the ability to measure the change in ground levels at millimetre accuracy over large areas on a monthly basis, providing the opportunity to monitor bridges, roads, dams and other linear infrastructure cost effectively.

Thanks for being part of the Geoimage ecosystem. We hope your team is as excited about 2019 as we are!

10 Jan 2019

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.
