CPW Abert's Squirrel Shapefile Download
收藏资源简介:
Last updated December, 2025 AbertsSquirrelOverallRange is an ESRI shapefile encompassing the observed range of a population of Abert's squirrel in Colorado. This information was derived from Colorado Parks and Wildlife field personnel. Data was captured by digitizing through a SmartBoard Interactive Whiteboard using topographic maps and NAIP imagery at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing Mapping Resources. GeoWorld 16(3):32-35). These data are updated on a four year rotation with one of the four Colorado Parks and Wildlife Regions updated each year. These data are not updated on a statewide level annually.
最后更新时间:2025年12月。艾伯特松鼠全域分布数据集(AbertsSquirrelOverallRange)为ESRI形状文件(ESRI shapefile),涵盖科罗拉多州境内艾伯特松鼠种群的实测分布范围。该数据集的信息源自科罗拉多州公园与野生动物管理局的野外工作人员。数据通过SmartBoard交互式白板(SmartBoard Interactive Whiteboard),依托多比例尺地形图与美国农业部农业航拍计划影像(NAIP imagery)进行数字化采集(Cowardin, M.、M. Flenner,2003年3月,《最大化制图资源》,《地理世界》第16卷第3期:32-35页)。该数据集采用四年轮换更新机制,每年更新科罗拉多州公园与野生动物管理局下辖四个区域中的一个区域的数据,不会每年开展全州范围的更新。
