摘要：Geomatica 9 is the latest version of PCI Geomatics geospatial image processing software product. It is particularly significant because it brings together into one integrated system advanced tools for remote sensing,photogrammetry,cartography and GIS. This merging of image processing and GIS within a single environment is one of PCI Geomatics key philosophies. This paper focuses mainly on the capabilities of Geomatica for orthorectifying very high resolution (VHR) satellite imagery. Orthorectified VHR satellite imagery is proving significant in the areas of cadastral mapping,agricultural,forestry and urban monitoring. VHR imagery would include products from the IKONOS,Quick Bird,EROS and SPOT-5 satellites. Based on rigorous parametric satellite models developed by Dr Thierry Toutin of the Canada Centre for Remote Sensing,Geomatica supports all the commercial VHR sensors. Rigorous sensor models offer the highest theoretical accuracy when orthorectifying imagery. The Rational Polynomial Coefficient (RPC) method of orthorectification is also supported by Geomatica and considered in the paper. Including the latest modification to the RPC model released by Space Imaging for their IKONOS imagery. Geomatica 9 supports block bundle adjustment of satellite imagery. In the way that block bundle adjustment reduces the number of Ground Control Points required to orthorectify a block of aerial photographs,the same concept is applied within Geomatica to reduce the time and cost required to map large areas. From sensors such as QuickBird and IKONOS,both panchromatic and multispectral imagery taken over the same area is available. A method of performing data fusion on these data within Geomatica is considered which preserves the original colour and detail of the input imagery.
