USGS GAP Hawaii 2001

The GAP/LANDFIRE National Terrestrial Ecosystems data represents a detailed vegetation and land cover classification for the Conterminous U.S., Alaska, Hawaii, and Puerto Rico.GAP/LF 2011 Ecosystems for the Conterminous U.S. is an update of the National Gap Analysis Program Land Cover Data - Version 2.2. Alaska ecosystems have been updated by LANDFIRE to 2012 conditions (LANDFIRE 2012). Hawaii and Puerto Rico data represent the 2001 time-frame (Gon et al. 2006, Gould et al. 2008). The classification scheme used for the Alaska and the lower 48 states is based on NatureServe’s Ecological System Classification (Comer et al. 2003), while Puerto Rico and Hawaii’s map legend are based on island specific classification systems (Gon et al. 2006, Gould et al. 2008).

GAP/LANDFIRE国家陆地生态系统数据代表了美国本土、阿拉斯加、夏威夷和波多黎各的详细植被和土地覆盖分类。美国本土的GAP/LF 2011生态系统是国家差距分析计划土地覆盖数据-2.2版的更新。阿拉斯加的生态系统已被LANDFIRE更新至2012年的状况(LANDFIRE 2012)。夏威夷和波多黎各的数据代表2001年的时间框架(Gon等人,2006年,Gould等人,2008年)。阿拉斯加和48个州的分类方案是基于NatureServe的生态体系分类(Comer等人,2003年),而波多黎各和夏威夷的地图图例是基于岛屿的具体分类系统(Gon等人,2006年,Gould等人,2008年)。
