Vegetation - Fish Slough [ds985]
收藏资源简介:
A fine-scale vegetation classification and map of a portion of the Fish Slough Area of Critical Environmental Concern (ACEC) (including the California Department of Fish and Wildlife (CDFW) Fish Slough Ecological Reserve) in Inyo and Mono Counties, California, was created by the CDFW Vegetation Classification and Mapping Program (VegCAMP). The vegetation classification is derived from floristic field survey data collected during September 2011, November 2012 and June 2013 and is based on previously described Alliances and Associations, with a few new provisional types included. The map was produced using heads-up digitizing using true-color 2012 1-meter National Agricultural Imagery Program (NAIP) imagery as the base. Supplemental imagery included 2012 1-meter NAIP Color Infrared and imagery available through Bing Maps and Google Earth. The minimum mapping unit (MMU) is 1 acre for upland habitats and ¼-acre for wetland habitats. Field reconnaissance and field verification enhanced map quality. The final map includes a total of 365 polygons representing 40 vegetation map classes.
加利福尼亚州因约县与莫诺县境内的菲什斯卢什关键环境关注区(Fish Slough Area of Critical Environmental Concern, ACEC,包含加州鱼类和野生动物部(California Department of Fish and Wildlife, CDFW)下属的菲什斯卢什生态保护区)的部分区域的精细尺度植被分类与地图,由CDFW植被分类与制图项目(Vegetation Classification and Mapping Program, VegCAMP)编制完成。本次植被分类基于2011年9月、2012年11月及2013年6月采集的植物区系野外调查数据,参考已发表的群丛联盟(Alliances)与群丛(Associations)分类体系,并纳入少量新的暂定类型。该地图以2012年1米分辨率的美国国家农业影像计划(National Agricultural Imagery Program, NAIP)真彩色影像为底图,采用目视数字化(heads-up digitizing)方式生成;辅助影像数据源包括2012年1米分辨率的NAIP彩红外影像,以及必应地图(Bing Maps)与谷歌地球(Google Earth)提供的影像数据。其最小制图单元(Minimum Mapping Unit, MMU)针对陆地生境设定为1英亩,湿地生境则为0.25英亩。野外踏勘与实地校验工作提升了本地图的制图质量。最终地图共包含365个多边形图斑,对应40个植被制图类别。
