[et al.]. [Ottawa] : Natural Resources Canada, c2012. [1] p. : col. photos Caption title. Includes bibliographic references. "A new orthorectification procedure was successfully applied to Landsat-7 data for creating a large area mosaic of the Arctic islands. Results indicate that RMS planimetric positional errors are 7 to 8 m for GCP and 3 to 4 m for CNJ. With available GCP limited to approximately 5 m known accuracy, these seamless map products can be considered accurate to approximately 20 m, or less than one image pixel. An early version of this mosaic was described by J. Gibson, and all digital data of this final version, including some three-band composite images, are now available for free download through GeoGratis. Landsat-7 is currently the best spatially and radiometrically accurate Landsat product for the Canadian Arctic"--Summary. gccst Cartography gccst Geographic data Gibson, Jack. Canada.
