1 NOVEMBER, 2010 Happy Days Are Here Again Discounts Galore! The recent performance of the Aussie Dollar has seen a rush on the very high resolution satellite sales as clients take advantage of the reduced prices for imagery such as WorldView-2, QuickBird, GeoEye-1 & IKONOS. With all of Geoimage s high resolution imagery being quoted in US dollars (and converted to Australian dollars at the time of invoicing), a 10% rise in the Australian dollar exchange rate equates to a 10% discount on our imagery. The discounting does not stop there!!! With the minimum areas and pricing of WorldView-2 stereo data being slashed recently, many clients are benefi tting by acquiring high resolution DEMs with 1m contours and 0.5m ortho imagery over sites around the world at a fraction of the cost of many aerial solutions. Pearl and Hermes Atoll, North-western Hawaiian Islands, USA DigitalGlobe There surely has never been a better time to acquire high resolution datasets from satellite. Be quick to contact Geoimage for a quotation while the good times roll. STOP PRESS It s official, Geoimage is thrilled to announce that all WorldView-2 and QuickBird archive orders over 100 sq km s will now be discounted by a further 10% until mid December So give our friendly staff a call to take advantage! GeoSpatial Solutions Team A recent study into the effects of drought on koala habitat for Logan City Council (Queensland, Australia) The GeoSpatial Group recently undertook a temporal change mapping project over a target study area for Logan City Council to view the effects of the drought on koala habitats. The team developed a series of statistical analyses on temporal satellite data to distinguish changes in natural bushland within a specifi ed study period. With reference to ancillary weather records sourced from the Bureau of Meteorology we were able to identify periods of suspected drought and assess the spatial change in vegetative properties and the intensity of these changes using a number of recognised indices. James McDonnell - Environment & Sustainability Manager for Logan City Council, commented that; Koalas populations expand and contract in response to drought. The GEOIMAGE drought metric project demonstrated the technical link in remote sensing forest health for koala population monitoring - innovation with huge potential given climate change. Our team is highly experienced in acquiring the most suitable satellite imagery and undertaking the most appropriate statistical analyses to develop a solution tailored to our clients needs.

2 Study places where it is not safe to go back in the water Geoimage was recently approached by a client looking for alternatives to sending fi eld survey teams into a remote and hazardous environment. The client has been undertaking an environmental impact assessment of the construction of a coal loading terminal and associated infrastructure on an intertidal island in Central Queensland. Associated with these studies have been a number of fi eld surveys, at great expense and risk. Access to the site is very diffi cult and the occurrence of saltwater crocodiles makes the planning and risk assessment of fi eldwork almost as time consuming and costly as the actual fi eldwork itself. An integral part of the environmental assessment relied on having information relating to the drainage of tidal fl ows in areas designated for key infrastructure. Traditional survey methods required in situ measurement requiring the installation and monitoring of numerous measurement devices across the island or the capture of detailed survey data through ground survey or LIDAR. Geoimage was able to propose GeoEye-1 Imagery GeoEye 2010 IKONOS Imagery Space Imaging 2005 Quickbird Imagery DigitalGlobe 2008 The solution: Taking full advantage of its independence, Geoimage reviewed archived imagery from all the vendors and recommended the purchase of archive imagery from IKONOS, Quickbird and GeoEye-1. The critical part to the solution was the matching of archive image capture dates with known tidal levels to ensure the image time series adequately covered the tidal range in the project area. a signifi cantly cheaper solution that eliminated the need for ground survey, using Very High Resolution satellite imagery. Each epoch was then classifi ed into an intertidal land cover map using Geographic Object Based Image Analysis (GEOBIA). Classes were defi ned to show the regions of exposed saltpans, recently inundated saltpans, inundated saltpans and wetland vegetation, with an overall accuracy exceeding 90% for each epoch. The integration of these three epochs gave a clear qualifi cation of the occurrence of overland drainage and drainage channels. The outcome: The results of this project provided the client with valuable hydrologic information required to satisfy their environmental assessment across the study area, in a timely manner and at a fraction of the cost of capturing new imagery. Tide land cover classifi cation Geoimage 2010 Geoimage wins ALOS Reseller of the Year Award for the 3rd time! RESTEC (Japan) has announced that Geoimage has won an ALOS Reseller of the Year Award for our sales during This is the third year in a row that Geoimage has won this prestigious award. As Bob Walker, CEO of Geoimage says The ALOS satellite provides imagery and DEM information with a broad scale coverage and is a very important dataset for both Geoimage and our clients - our team is justifi ably proud that our hard work and expertise with satellite imagery has been recognised by RESTEC.

3 Bowen Basin Symposium The Bowen Basin Symposium was run by the Bowen Basin Geologists Group and the Geological Society of Australia and held from 6 to 8 October 2010 at the Mackay Entertainment and Convention Centre. The large turnout of +600 delegates highlighted the boom in Exploration and Development in the Queensland Coal Mining Industry, the coal seam gas developments and the emerging LNG export industry. Since the launch and commissioning of DigitalGlobe s WorldView-2 satellite in late 2009, Geoimage has been able to offer to the Coal Industry access to a system capable of; 0.5m colour imagery The ability for large area collects up to +10,000 sq km in the same overpass. E and N accuracies of better than 4m without ground control with a good DSM for orthorectifi cation, and accuracies of subpixel with a few ground control points. Stereo imagery capable of generating 1m DSMs with an accuracy of m. 8 band multispectral imagery for the most demanding spectral processing. Our GeoSpatial Group are using this imagery to do detailed assessments of vegetation communities. Geoimage had a trade booth at the symposium which highlighted the ways that we have used the WorldView-2 imagery to help our clients working in the Coal Industry. Active coal mine locations over the Bowen Basin in Queensland - false colour Landsat mosaic (bands 7,4,1) USGS Geoimage 2010 As part of its preparation for the Bowen Basin conference, Geoimage prepared a mosaic of very recent low cloud Landsat 5 imagery at 30m resolution over the Bowen Basin. The main dates used in this mosaic were late 2009 as the 2010 imagery was affected by the heavy rains this year. We are pleased to offer our clients a complimentary copy of the B741 colour composite of this mosaic in ECW format. Please contact dems@geoimage.com.au for your copy. Geoimage releases new DEM fl yer Since the ready availability of the WorldView-2 imagery in early 2010,Geoimage has processed a large amount of imagery from around the globe. In addition to the clarity, speed of capture and the 8 bands, we have been impressed by the geo-locational accuracy of the data. Orthoimages produced using a good Digital Elevation Model usually only require one accurate ground control point to be shifted into the correct location with a sub-pixel accuracy. This same accuracy is also achieved in the production of 1m resolution Digital Surface Models from WorldView-1 and WorldView-2 stereo pairs. Geoimage is now routinely achieving vertical accuracies of 0.5m 0.7m (LE90), with only one or two accurate ground control points required. This speed of capture and the amazing accuracies obtained are good news for clients requiring detailed terrain information over anywhere in the world. This brochure presents several case histories of the excellent results that we are now seeing from the WorldView DSMs. For large area coverage, Geoimage recommends DSMs produced from the ALOS PRISM sensor which are produced at a 5m cell size and a vertical accuracy of 3-5m. We are sure that you will be impressed with the results that have been documented in this fl yer, and if you have any queries, please contact one of our friendly team in either our Brisbane, Perth or Sydney offi ces or dems@geoimage.com.au.

4 Good news story of the week: Success in capturing imagery in Papua New Guinea Geoimage is pleased to advise that this winter has seen some excellent high resolution satellite imagery captured over many parts of Papua New Guinea. Traditionally PNG is extremely diffi cult to capture with low cloud coverage, however, both WorldView-2 & GeoEye-1 had great success this year. Route selection identifi ed on 50cm Pan-sharpened WorldView-2 imagery in natural colour draped over a 1m DEM DigitalGlobe 2010 Geoimage 2010 This high resolution satellite imagery is being used to better understand the natural and built environment. Geoimage regularly interprets this imagery to extract features such as assets, infrastructure and many different types of land cover types from highly managed areas and shallow water habitats which assist our clients to make better decisions in such a complicated geographic region. Lisa Dykes - Sales Manager for High Resolution imagery says PNG is always a tough area to image because of the weather constraints, but it is a region where Geoimage is currently seeing great demand for our services and products. With our satellite imagery partners making great efforts recently to capture large areas of PNG, any projects requiring high quality imagery will now be greatly advantaged by the fact that the satellite archive has been bolstered by such low-cloud and recent datasets. It is gratifying to see so much of this imagery now being used by many of our clients and so much interest in Geoimage s datasets.
