Erosion Gully Density

\n\nThis data set is a gully density map (km/km2) covering river basins containing\nintensive agriculture.The data set is a product of the aWater-borne erosion\nand sediment transporta project of the National Land and Water Resources Audit\n(NLWRA).The digital map data is provided in geographical coordinates based on\nthe World Geodetic System 1984 (WGS84) datum. This raster data set has a grid\nresolution of 9a3(approx 250 metres).The data set may be of use to researchers\nand policy makers in need of national or regional scale land use data.Key\nwords: gully density; gully erosion; soil erosion\n\nSee [further metadata](http://data.daff.gov.au/anrdl/metadata_files/pa_egd__r9cl\n__00811a00.xml) for more detail.\n\n本数据集为沟谷密度图（单位：千米/平方千米），覆盖包含集约化农业的流域范围。本数据集系国家土地与水资源审计局（National Land and Water Resources Audit, NLWRA）水蚀与泥沙输运项目的研究成果。该数字地图数据采用基于1984世界大地测量系统（World Geodetic System 1984, WGS84）的地理坐标基准。本栅格数据集的网格分辨率为9a3（约250米）。本数据集可面向需要国家级或区域级尺度土地利用数据的科研人员与政策制定者提供支撑。关键词：沟谷密度；沟蚀；土壤侵蚀。如需获取更多详细信息，请参阅[补充元数据](http://data.daff.gov.au/anrdl/metadata_files/pa_egd__r9cl__00811a00.xml)。
