Description
Summary:Lakes were mapped based on Landsat mosaics from 2001/2002 and 2009. Maps are stored as ESRI shapefile. Projection: UTM 52N, Datum: WGS84, Extent: South-bound Latitude: 60.40 * West-bound Longitude: 113.00 * North-bound Latitude: 65.60 * East-bound Longitude: 133.40 Methods: Waterbody mapping was carried out using two mosaics of Landsat satellite images: A Landsat TM mosaic consisting of 25 images acquired during the summer of 2009 and a mosaic of 31 Landsat ETM+ images recorded during two consecutive summers in 2001 (12 images) and 2002 (19 images). Heavy cloud cover in 2001 and 2002 made it necessary to combine remote sensing data from these two years in order to create a cloud free baseline for change detection over the entire region covered by the (cloud-free) 2009 mosaic. The average day of year (DOY) for the 12 images in our 2001 dataset was therefore 213 ±19 (1st August), and for the 19 images in the 2002 dataset 212 ±15 (31st July). Precipitation, which is likely to affect the areas of lakes, did not ...
