Check Files 2d zsh zpt: Difference between revisions

'''Note: ''' More than one Z shape layer can modify the same elevation point. For example if two breaklines are applied which intersect then the later occurrence in the geometry control file is given preference. Multiple objects within a GIS layer, may also modify the same elevation point (zpt), for example overlapping polygons. In the _zsh_zpt check file, all modifications byin each Z Shape layer and for each 2D Z Shape layers are reported. If there are multiple modifications to an elevation point, the dz value is the modification from the previous elevation. For example, if an elevation point starts with an elevation of 10.0, which is raised to 12.0 (dz = 2.0), before being raised to 12.5 by a second Z Shape layer, the dz reported for the second layer will be 0.5 and not 2.5 (i.e. compared to the base elevation). The final elevations are reported in the [[Check_Files_2d_zpt | 2d_zpt check file]].
