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编辑后的统计型多边形数据，其源自从萨布利特羚羊种群单元（PR401）内415头迁徙羚羊所采集的GPS项圈数据。为本数据集提供数据支撑的共有九项独立的GPS项圈研究，其项圈部署范围从大提顿国家公园一路向南延伸至80号州际公路。数据采集周期为2002年至2025年。针对GPS数据，按高、中、低三种使用强度采用线缓冲区（Line Buffer，300米）方法进行分析；针对中途停留位点，则采用布朗桥运动模型（Brownian Bridge Movement Model, BBMM）开展分析。上述分析基于羚羊从冬季栖息地向夏季栖息地（及返程）的移动路径，以及其在迁徙途中的停留时长，生成了对应的多边形数据。鉴于WGFD在土地利用规划工作中需与土地管理机构协同合作，原始数据经编辑后更便于实地应用。 注意：构成完整廊道数据集的其余要素类（FCs）均采用相同的元数据内容。
