The title compound, C(14)H(21)Cl(3)O(9)·2H(2)O, is a disaccharide constructed from a galactose and a fructose. In the mol-ecular structure, the tetra-hydro-furan five-membered ring and tetra-hydro-pyran six-membered ring assume envelope and chair conformations, respectively. An extensive O-H⋯O hydrogen-bonding network occurs in the crystal structure.
Triangulation of LiDAR data can produce unnatural water surface. Therefore, it is necessary to hydroflatten LiDAR data. Hydro-flattening is driven primarily by cartographic mapping needs, and can also help hydrologic analysis, because hydro-flattened surfaces behave naturally; allowing water flow from upstream to downstream. Detailed hydro-flattening requirements have been stated by USGS, which...
