Space Imaging certification requirements included the ability to load, display, read coordinates and orthorectify IKONOS stereo models, and the ability to block adjust IKONOS stereo models with or without ground control. Tests performed included image coordinate measurements, orthorectification with a DEM, and various block adjustments of two stereo pair using varying degrees of ground control. Space Imaging's acceptance criteria compared results between the Space Imaging ground station and the software under test, Geomatica 9. To make allowance for the operator's ability to read points within an image, an agreement within ±1 pixel is generally acceptable. The results were that PCI Geomatics' Geomatica 9 passed all tests.
PCI Geomatics was first in the geomatics software industry to announce the ability to orthorectify Geo OrthoKit IKONOS satellite imagery from Space Imaging, the world's leader in providing Earth imagery and related services to commercial and government markets. In certifying PCI Geomatics' Geomatica 9 RPC block adjustment technology, Space Imaging has taken the first steps to providing a template for successful testing of other photogrammetric software implementations of the Space Imaging RPC Block Adjust technique.
"Distinctions of this importance have great meaning in our industry, although this may not be clearly realized by the general public." states Dr. Robert Moses, President and CEO of PCI Geomatics. "Receiving such an acknowledgement from Space Imaging for our accuracy is a greatly appreciated validation of PCI Geomatics development efforts to bring forward our best work in Geomatica 9."
