资源简介：
Two hydro-DEM versions available. Hydro elevation surface derived from Iowa lidar collected during 2007-2010. S-Library The Iowa S-Library series of elevation data are watershed-scale, high-resolution rasters that have been hydro-conditioned and include some hydrologic enforcement. These data should be considered 'bare earth data' and are suitable for large scale examination of the landscape using a variety of terrain analysis methods and visualization techniques. Full metadata available here: https://acpfdata.gis.iastate.edu/ACPF/SLib2m_metadata.pdf P-Library The Iowa P-Library series of elevation data are watershed-scale, high-resolution rasters that have been hydro-conditioned to remove artifacts of the LiDAR collection process. These data should be considered 'bare earth data' and are suitable for large scale examination of the landscape using a variety of terrain analysis methods and visualization techniques.
