Supplemental Information

History: This layer utilised the LANDSAT TM data collected as part of the 1990 - 1995 Agricultural land cover change project. Processing of this dataset included the use of the ERIM image restoration algorithm giving a much sharper image than previously achieved with the TM100_1993 dataset. Imagery used in this dataset was acquired primarily over summer 1994/95 with dates ranging from December 1994 to February 1996. Relationship to other Datasets: This layer is derived from TM100_93 Current Design Issues: This layer has been designed to store remotely sensed LANDSAT image mosaics for use in geospatial applications.
