PCI Geomatics and Natural Resources Canada Announce Support of SPOT 5 Rigorous Sensor Model 02.12.2003
PCI Geomatics and Natural Resources Canada (NRCan) announced support for data (10-metre, 5-metre and 2.5-metre pixel spacing) from the SPOT 5 satellite in PCI Geomatics' Geomatica OrthoEngine software.
PCI Geomatics will include the new SPOT 5 Rigorous Sensor Model within Geomatica, the company's popular all-in-one flagship software solution for remote sensing, spatial analysis, cartography and photogrammetry.
Using an initial version of the physical rigorous 3-D model developed by scientists at NRCan's Canada Centre for Remote Sensing, researchers have achieved high accuracy under a variety of image-terrain conditions. After verification and testing over the next few months, PCI Geomatics expects to further refine these results.
PCI Geomatics was the first provider of image-centric geomatics software solutions to support the IKONOS Rigorous Sensor Model within its geomatics software suite. It is also the only company currently offering support for the QuickBird Rigorous Model. Both models were developed through the cooperative efforts of PCI Geomatics and NRCan.
The development and support of the SPOT 5 Rigorous Model have provided users of satellite data with a more accurate and less restrictive model for using SPOT Image SPOT 5 satellite data, resulting in fewer limitations to criteria such as terrain, slope and other geographical considerations.
SPOT 5 was launched on May 4, 2002, and contains two independent optical instruments (HRGs). Each includes two panchromatic (5-metre) CCD arrays that can be combined to generate a 2.5-metre image product, as well as three multispectral (10-metre) channels and one short-wave infrared (20-metre) channel. Each SPOT 5 HRG has an imaging swath of 60 kilometres. Like the previous SPOT platforms, SPOT 5 is able to collect across-the-track stereo data, by imaging the same area from two different orbits. Moreover, the SPOT 5 platform is capable of along-track stereo viewing through a dedicated stereo sensor.
