Historical charts, soundings and surfaces (DEMs) of western Victoria, Australia

This data repository hosts the georeferenced nautical charts, digitised soundings, converted soundings (Australian Height Datum 1994), surface masks and interpolated surfaces (DEMs) of seven historical surveys conducted in western Victoria during the 19th century. These charts produced by H. J. Stanley, J. Barrow and J. B Mason for Portland Bay (1854, 1869 and 1972), Port Fairy (1870), Lady Bay-Warrnambool (1870) and Apollo Bay (1868 and 1889), were obtained in digital format from the State Library Victoria (www.slv.vic.gov.au). For specific characteristics of individual charts refer to Table 1. These nautical charts provide an unique historical perspective of the coast during the time of the surveys. These datasets were used by the author and collaborators to understand sedimentary dynamics and quantify human alterations in the coastal zone, by comparing their surfaces to contemporary Multibeam Echosounding (MBES) bathymetry and Light Detection and Ranging (LiDAR) data. The georeferenced nautical charts and interpolated surfaces are in Geotiff format, and the digitised soundings, converted soundings and surface masks are in shapefile format. Files are compressed and organised in sub-folders inside specific charts.本数据集仓储收录了19世纪于维多利亚州西部开展的7项历史勘测所生成的地理配准海图、数字化测深数据、转换后测深数据（采用澳大利亚1994国家高程基准）、表面掩膜及插值表面（数字高程模型，DEM）。上述海图由H·J·斯坦利（H. J. Stanley）、J·巴罗（J. Barrow）及J·B·梅森（J. B Mason）绘制，覆盖波特兰湾（1854年、1869年、1972年）、仙女港（1870年）、瓦南布尔女士湾（1870年）以及阿波罗湾（1868年、1889年）的勘测成果，数据以数字格式从维多利亚州立图书馆（www.slv.vic.gov.au）获取。如需查阅单张海图的具体特征，请参阅表1。 这批海图为勘测时期的海岸风貌提供了独一无二的历史视角。本数据集的作者及合作者通过将这些插值表面与当代多波束测深（Multibeam Echosounding, MBES）水深地形数据以及激光雷达（Light Detection and Ranging, LiDAR）数据进行对比，以此解析海岸带沉积动力学过程并量化人类活动对海岸带的改造程度。 地理配准海图与插值表面采用GeoTIFF格式存储，数字化测深数据、转换后测深数据及表面掩膜则采用Shapefile格式。所有文件均已压缩，并按具体勘测海图分类存储于子文件夹中。
