CPW Sandhill Crane Shapefile Download

Last updated December, 2025 GreaterSandhillCraneOverallRange is an ESRI shapefile encompassing the observed range of a population of Greater Sandhill Cranes in Colorado. LesserSandhillCraneOverallRange is an ESRI shapefile encompassing the observed range of a population of Lesser Sandhill Cranes 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.最后更新于2025年12月。大沙丘鹤整体分布范围数据集（GreaterSandhillCraneOverallRange）是一份ESRI形状文件（ESRI Shapefile），涵盖了科罗拉多州境内大沙丘鹤种群的观测分布区域；小沙丘鹤整体分布范围数据集（LesserSandhillCraneOverallRange）同样为ESRI形状文件，涵盖了科罗拉多州境内小沙丘鹤种群的观测分布区域。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。数据通过使用不同比例尺的地形图与美国农业部农业航拍图像（NAIP imagery），经SmartBoard交互式白板数字化采集得到（引用来源：Cowardin, M., M. Flenner. 2003年3月. 《最大化测绘资源利用》. 《GeoWorld》第16卷第3期：32-35）。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，不会每年对全州范围的数据进行更新。
