Landsat mosaics 2001/2002 and 2009, Central Yakutia, with links to GeoTIFFs@en
收藏资源简介:
Two mosaics from Landsat scenes were constructed for the study area for the years 2001/2002 and 2009. Mosaicking process was done in ERDAS IMAGINE 9.1. We used the \"Mosaic Images\" processing chain of the \"data preparation\" menu. After adding all images into the \"Mosaic Tool Viewer\", the image quality within the overlap areas were evaluated. Cutlines between neighboring images were drawn manually, in order to create a cloud free coverage for the entire area. Output map area was set to \"Union of all inputs\", output cell size to 30 (2001/2002 mosaic) and 32 m (2009 mosaic). No color corrections along the border of cutlines or across the images have been applied. All Landsat scenes were utilized in Standard Terrain Correction Level (L1T). Further absolute and relative georeferencing of the imagery was not necessary due to the high accuracy of fit (<= 1 pixel) within both mosaics and between them. […]
