Christmas Island Vegetation and Clearing Dataset

The Christmas Island Vegetation and Clearing Map was developed through a collaborative project by Geoscience Australia, Christmas Island Phosphates, and Christmas Island National Park during the 2013/2014 financial year. The map classifies the full extent of Christmas Island into vegetation and land cover classes. The dataset contains four attribute fields;- Level 1 classification- Level 2 classification- Mean tree height (Mean_TreeH)- Area (square m)The majority of data was gathered in 2011, with an exception being the rehabilitation boundaries which are up to date as of May 2014.The data represent the best position achievable with the limited resources available during the project's timespan. Geoscience Australia recognises that some data inputs could be improved with additional field checking. The boundaries of cleared areas have been verified in some cases only and may extend into primary, uncleared vegetation in places; ground-truth verification is strongly advised. Consequently, this information should not be relied upon as the sole information source when making operational decisions.

圣诞岛植被与清退地图（Christmas Island Vegetation and Clearing Map）由澳大利亚地质调查局（Geoscience Australia）、圣诞岛磷酸盐公司（Christmas Island Phosphates）及圣诞岛国家公园（Christmas Island National Park）于2013/2014财年联合合作项目研发而成。该地图将圣诞岛全域划分为植被与土地覆盖类别。本数据集包含四类属性字段：一级分类、二级分类、平均树高（Mean_TreeH）以及面积（单位：平方米）。绝大多数数据采集于2011年，仅修复工程边界数据更新至2014年5月。本数据集为项目周期内依托有限资源所能达成的最优成果。澳大利亚地质调查局指出，部分数据输入项可通过补充野外核查得到优化。仅部分已清理区域的边界已完成核验，部分区域的边界可能延伸至原生未清理植被范围内；强烈建议开展地面实况验证。因此，在制定运营决策时，不应仅将本信息作为唯一信息来源。
