ZY-3 is an optical imaging satellite with a Multispectral Camera (MSC), which collects imagery at a resolution of 5.8m with four spectral bands (Blue, Green, Red, Near-IR). ZY-3 also has a Three Line Array (TAC) camera, which collects panchromatic images at 2.1 m (nadir) and 3.5m (forward and backward cameras).
PCI Geomatics conducted quality control on ZY-3 imagery to determine the accuracy, and found that the correction level is very precise using Rational Polynomial Coefficients (RPCs).
“We worked closely with an image collected over Hong Kong on March 2013 to assess the automated methods used to correct ZY-3 images using RPCs,” said Dr. Philip Cheng, Senior Scientist at PCI Geomatics. “Our software includes support for pansharpening, and high resolution digital elevation model extraction using imagery from the single pass stereo mode.”
A sample image of Hong Kong (processed and pansharpend using PCI Geomatics software) is available here: www.pcigeomatics.com/images/ZY-3/HongKong.jpg.
Support for ZY-3 is available in Geomatica and GXL 2013.
