Brief description

A Landsat TM image was cut using a NATMAP Geoscience Australia 1:250 000 scale map named Augusta (Map number SI50-9) and was saved in GeoTIFF format. The image was geometrically rectified to GDA94 (Datum) and MGA50 (Projection) and a dual enhancement technique was conducted to Landsat TM satellite data where land was enhanced using bands 741 (RGB) and water was enhanced using bands 321 (RGB). This is one of a series of tiles processed by ERIN from Coastal Atlas project in the 1990's.
