Human Influence Index Dataset of the Last of the Wild Project, Version 2, 2005 (LWP-2)

The Human Influence Index Dataset of the Last of the Wild Project, Version 2, 2005 (LWP-2) is derived from the LWP-2 Human Footprint Dataset. The gridded data are classified according to their raster value (wild = 0-10; not wild >10). The ten largest polygons of more than 5 square kilometers within each biome by realm are selected and identified. The data set was produced by the Wildlife Conservation Society (WCS) and the Columbia University Center for International Earth Science Information Network (CIESIN). The global and continental data are available. The purpose of the data set is to provide an updated map of wild areas in geographic projection which can be used in wildlife conservation planning, natural resource management, and research on human-environment interactions.

2005年发布的《荒野最后地带项目》第二版人类影响指数数据集（LWP-2）源自LWP-2人类足迹数据集。该网格化数据依据栅格值进行分类：荒野区域对应0-10区间，非荒野区域对应大于10的数值区间。针对每个生物地理界下的生物群系，本数据集选取并识别出其中面积超过5平方千米的十大最大多边形区域。本数据集由野生动物保护协会（Wildlife Conservation Society, WCS）与哥伦比亚大学国际地球科学信息网络中心（Center for International Earth Science Information Network, CIESIN）联合编制。全球及大洲尺度的数据均已公开可用。本数据集旨在提供经更新的地理投影荒野区域地图，可应用于野生动物保护规划、自然资源管理以及人类与环境交互作用相关研究。
