ERIN Dual-processed Landsat TM tiles in Western Australia - Perth tile

A Landsat TM image was cut using a NATMAP Geoscience Australia 1:250 000 scale map named Perth (Map number SH50-14) 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.采用澳大利亚地球科学局（Geoscience Australia）出品的比例尺为1:250000的NATMAP地图（图幅号SH50-14，名称为《珀斯》），对一幅陆地卫星专题制图仪（Landsat TM）影像进行裁切，最终以GeoTIFF格式存储。 该影像已完成几何校正，采用澳大利亚大地基准1994（GDA94）与澳大利亚地图投影带50（MGA50）坐标系；针对该Landsat TM卫星影像采用双增强技术开展处理：以7、4、1波段组合实现陆地信息增强（RGB模式），以3、2、1波段组合实现水体信息增强（RGB模式）。本数据集为20世纪90年代由ERIN从海岸图集（Coastal Atlas）项目中处理的一系列分幅影像之一。
