Service Description:

All scenes were processedto Standard Terrain Correction Level 1T by the United States Geological Survey (USGS).Further processing performed by the Canada Centre for Remote Sensing included conversion ofsensor measurements to top of atmospherereflectance, cloud and cloud shadow detection, reprojection,selection of best measurements, mosaic generation ,noise removal and qualitycontrol. To provide a clear sky measurement for each location in Canada, data from the years2009, 2010, and 2011 were used, but 2010 was preferentially selected. Bands 3 (0.63-0.69 μm), 4(0.76-0.90 μm), 5 (1.55-1.75 μm), and 7 (2.08-2.35 μm) are provided in this version assignificant atmosphere effects strongly limit the quality of the blue (0.45-0.52 μm) and green(0.52-0.60 μm) bands. Multi-criteria compositing was used for the selection of the mostrepresentative pixel. For ETM+ onboard Landsat 7 a scan line malfunction caused missing linesof data in all scenes collected after May 2003. Atmosphere and target variability between scenescause these lines to have significant radiometric differences in some cases. A Fouriertransformation approach was applied to correct this occurrence. This mosaic was developed forland cover and biophysical mapping applications across Canada. Other applications of these dataare also possible, but should consider the temporal and spectral limitations of the product.Research to enhance the spatial, spectral and temporal aspects are in development for futureversions of moderate resolution products from historical Landsat sensors, Landsat 8, and Sentinel2 data.The source data is accessible at https://neodf.nrcan.gc.ca/neodf_cat3/
