AntelopeMigrationIdentifiedSubletteWGFDCorridor

These data represent the WGFD-edited version of statistically-based polygons derived from GPS collar data collected from 415 antelope migrating in the Sublette antelope herd unit (PR401). There were nine different GPS collar studies that contributed to this data set which included collaring efforts from Grand Teton National Park all the way south to Interstate 80. The data were collected from 2002 through 2025. The GPS data were analyzed using Line Buffer (300 meter) for the high, medium and low use levels and Brownian Bridge Movement Model (BBMM) for stopovers, which produced polygons based on where animals traversed from winter range to summer range (and back) and how much time they spent along the way. The original data were edited to be more manageable on the ground as the WGFD works with land management agencies during land use planning. NOTE: The same metadata content is used for the other FCs comprising the entire corridor dataset.本数据集为经WGFD编辑的版本，其数据源自在萨布利特羚羊群单元（PR401）内迁徙的415只羚羊的GPS项圈监测数据。本数据集共纳入9项不同的GPS项圈研究，项圈布设范围覆盖从大提顿国家公园一路向南至80号州际公路的区域。数据采集时间为2002年至2025年。针对该GPS监测数据，研究人员采用300米线缓冲区分析法划分高、中、低三种使用等级，并通过布朗桥运动模型（BBMM）识别停留点；最终生成的多边形要素涵盖了羚羊在冬季栖息地与夏季栖息地间（及返程）的移动路径，以及其途中停留的时长信息。由于WGFD在土地利用规划工作中需与各类土地管理机构协作，原始数据已被编辑优化，以提升实地应用的可操作性。注：构成完整廊道数据集的其余要素类（Feature Classes，FCs）均采用相同的元数据内容。
