	'''Note: ''' More than one Z ~~shape~~ layer can modify the same elevation point. For example, if two separate breaklines layers are applied which intersect, then the later occurrence in the TUFLOW Geometry control file (.tgc) is given preference. Multiple objects within a single GIS layer may also modify the same elevation point (zpt), for example overlapping polygons. In the _zsh_zpt check file, a separate reporting point is created for each modification to a zpt's elevation from all objects, in all Z Shape layers. If there are multiple modifications to an elevation point, the dz value is the most recent change from the last assigned 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). Where a zpt has been modified multiple times, the _zsh_zpt check file will include multiple objects at the same zpt location that details each change from the previous elevation. The final elevations are reported in the [[Check_Files_2d_zpt \| 2d_zpt check file]].		'''Note: ''' More than one Z Shape layer can modify the same elevation point.
