Sir Samuel regolith landforms digital data

The Sir Samuel 1:250,000 regolith-landform map illustrates the distribution of regolith materials and the landforms on which they occur, described using the RTMAP scheme developed by Geoscience Australia, drawn over a 3-band Landsat Thematic Mapper image.

塞缪尔爵士（Sir Samuel）1:250000比例尺风化壳-地貌图展示了风化壳（regolith）物质的分布及其赋存的地貌类型，该图采用由澳大利亚地质调查局（Geoscience Australia）研发的RTMAP制图方案进行要素描述，并基于3波段陆地卫星专题制图仪（Landsat Thematic Mapper）影像绘制完成。
