Wayne's World:

  

Happy Easter Everyone! We hope that your year has started well and that your projects and endeavours are progressing as planned.  


We have some great news as we start the New Year of further partnerships with satellite vendors.  You may have seen a recent press release detailing our exclusive partnership in Australasia with Skybox Imaging for their SkySat-1 imagery. We are very excited about the opportunity to provide this imagery to clients over the coming months and years.  

We have also now signed a Reseller Agreement with Blackbridge to be able to offer our clients RapidEye imagery.  We have seen the value of RapidEye imagery for some time and are delighted that we are now able to offer it as a valuable option for clients.

I would like to take this opportunity to thank all those clients who responded to our 2014 Client Feedback Survey.  It has become an essential tool for us as we try to stay connected, listen to our client’s needs and feedback and strive for improvement in what we do and how we do it.  I am personally delighted that despite the downturn in workload over the past year, budget restraints and competition generally that we have remained true to our core values of Technical Excellence and Customer Service. We have also identified a number of products and services as well as general improvements that we will work on as a result of the survey.


At Geoimage we pride ourselves on being Unique.  What does that really mean?  Well we believe that our primary focus on satellite imagery, our access to more satellite imagery providers than ever before and anyone else, our depth of technical experience and skill and our approach to customer service all add to make us unique in the industry.  There are risks and benefits that come with being unique but we truly believe that we are now “The Specialists in Satellite Imagery” in Australia.


If you have any questions at all about whether satellite imagery and our specialised services may bring further efficiency to your projects or workflows please do not hesitate to contact our sales team.   One thing we all like to do is to talk with our clients and see if we can help provide a valuable solution.



RapidEye: Geoimage now offers the "Five Fives" solution to it's clients

Geoimage has recently signed a distribution agreement with BlackBridge to market and sell RapidEye products throughout the world.


RapidEye is a unique satellite option - offering a five fives solution:


  • 5 satellites
  • 5 metre resolution
  • 5 spectral bands
  • Up to 5 million sq kms collected every day
  • 5 billion sq kms in archive
The five satellite RapidEye constellation offers enhanced earth observation capabilities to its customers. The combination of large area coverage, frequent revisit intervals, high-resolution and multispectral capabilities are unrivalled in the industry.

Environmental monitoring and mapping of deforestation and forest degradation has become quite a priority and with the RapidEye constellation, Geoimage are now able to offer clients a large area solution, especially over cloudy areas such as Papua New Guinea and Indonesia.


The red edge band together with the broad area coverage and speedy capture time is ideal for assessing change detection of land based features, assessment of current land use, disaster response and reducing emissions from deforestation and forest degradation.

  
RapidEye satellite data has also been used to enforce environmental law in Brazil.

Taking the stress out of mine disturbance

Geoimage & Gaia Resources:

Since the introduction in 2012 of the Mining Rehabilitation Fund (MRF) Act in Western Australia, a number of changes to the regulations around disturbance mapping have taken place.  As a result, all tenement and lease holders on Mining Act 1978 tenure are obligated to report the type and number of hectares of disturbed land to the Department of Mines and Petroleum (DMP) by the 30th June each year. Geoimage along with our partners Gaia Resources, are utilising our strong background in satellite imagery and spatial data to provide accurate and precise results for reporting disturbed land.

Gaia Resources deliver sustainable technology solutions to companies that work with the environment.  They provide services across spatial, software engineering, support, training and hosting.  Operating since 2004, Gaia Resources has a strong reputation as an independent provider able to deliver solutions across a range of areas in the environmental space and was the ideal partner for Geoimage.

Through our partnership, we are able to inform and produce a comprehensive end-to-end solution for clients through satellite imagery acquisition, classification of disturbance into MRF categories, mapping and quantifying disturbed land into hectares and final DMP compliant reporting.

With 25 years in the remote sensing and satellite imagery industry, Geoimage have developed a range of in-house processing techniques to provide the most accurate and precise data as possible. Furthermore with the flexibility to work alongside existing datasets, defining a baseline is a key objective that supports all ongoing work. By investing early in creating a solid and well supported baseline, there will be a significant reduction in anomalous figures when reporting to the DMP, minimising the risk of potential audits and investigations into practices.

Geoimage and Gaia Resources are looking to further improve, innovate and refine upon current automatic classification techniques. With ongoing and consistent research and development, the workflows for the disturbance mapping chain are becoming more efficient and streamlined to benefit tight schedules and demand for the best quality of services. The investment in research and development and our drive to ensure the whole process runs automatically, aims to make this annual reporting requirement as stress free as possible.

For further information on our end-to-end MRF disturbance mapping solution, please contact either Geoimage or Gaia Resources.

Archaeology and Remote Sensing

Bob & Christine Walker:



How much easier would Indianna Jones have found his adventuring if he had available satellite imagery that we now consider as routine coverages?  How much less time he would have had to spend on the ground  battling the cursed snakes and how much more preparation he could have done before his field work?  Of course, the archaeologists are now playing catch up with  the mineral and oil exploration geologists who have been using satellite imagery since the ERTS1 imagery  became available in the mid 1970s.


Many of the techniques used by the “Space” Archaeologist are very similar to those used by the exploration geologists and  mainly involve  study of landscape features such as soil type, vegetation, rock outcrops,  topography and  relief. It is the ability of examining these features in single and multiple date imagery and at all scales from the regional to the detailed that is important in identifying features that are not visible from the ground.


Satellite archaeology is particularly useful in areas which are densely forested and lack modern settlements and infrastructure such as the Peten region of northern Guatemala.  The Peten is a hilly, karstic, thickly forested landscape which offers an incredible barrier for field archaeologists to penetrate. 


The NASA archaeologist Tom Sever and his team have used imagery to map undiscovered roads and causeways the ancient Mayans built to connect cities and settlements. These landscape artifacts represent the advantage of using remote sensing as these causeways are not visible from the ground. By mapping these forms, Sever is able to locate new sites and further uncover ancient Mayan methods of communicated and transportation. Sever and his team also use remote sensing methods to gather data on deforestation. The rain forests of the Peten are undergoing massive deforestation, and Sever’s remote sensing offers another window into this understanding and halting this destruction.

 
Dr. Sarah Parcak
 

As part of a pilot project to create a repeatable methodology to monitor site looting, Dr. Sarah Parcak, Associate Professor of Anthropology at the University of Alabama at Birmingham, deployed satellite imagery along with GIS analysis at the Egyptian pyramid fields of el Lisht and el Hibeh, two significant archaeological sites south of Cairo.

“Looting is a very sophisticated crime conducted in large part by professional criminals that know exactly what they are looking for,” Dr. Parcak explains. “I was convinced that satellite imagery is an ideal tool to track looting patterns, given that looting is commonly characterized by the digging of many small shallow pits that high-resolution imagery could easily identify, track, and monitor over time.”

 

The archaeological site of Portus, Italy, Rome’s Imperial site, built around 114 AD, provides a powerful example of how satellite imagery can impact the discovery process. For more than 30 years, a team of researchers from Southampton University had been working the site, which now lies under a landing pattern for Rome’s Leonardo da Vinci Fiumicino Airport, using primarily ground-based technology, and had yet to discover the city’s amphitheater and other key features.

Dr. Parcak collaborated with the Southampton team, to locate the amphitheater and to identify other key archaeological features using DigitalGlobe WorldView-2 imagery in place of magnetometers and other more conventional ground-based technologies.

Dr. Sarah Parcak, a pioneer in the new field of satellite archaeology, serves as the founding director of the Laboratory for Global Observation at the University of Alabama at Birmingham, where she is an Associate Professor in the Department of Anthropology. She is also the CEO of SpectralGlobe technologies, a company that specialises in using remote sensing technologies to provide innovative landscape solutions.
