cell side Zpt values, and creates sloping cells using the ZC, ZU, ZV and ZH values. It does insure a continuous flow path, but the spatial accuracy may become lower comparing to the approach of sampling elevation directly from DEM. For more discussion, please see <u>[[Quadtree_and_Sub-Grid_Sampling_FAQ#Why_shouldn.27t_I_use_Z_Shape_gully.2Fmin_lines_with_SGS_models.3F|SGS FAQ page]]</u>.
