The '''_2d_zln_zpt''' or '''_2d_zln_zpt_P''' check file is only created if a "<tt><font color="blue">Read GIS Z Line</font><font color="red"> ==</font></tt>" command has been specified in the model. This file contains information on the elevations points (zpts) that have been altered by the <font color="blue">Read GIS Z Line</font> commands.<br>
<br>
'''NOTENote:''' That ifIf using the "<tt><font color="blue">Read GIS Z Line MIN</font><font color="red"> ==</font></tt>" or "<tt><font color="blue">Read GIS Z Line GULLY</font><font color="red"> ==</font></tt>", points are not included in this check file. It is recommended that users migrate to the "<tt><font color="blue">Read GIS Z Shape</font><font color="red"> ==</font></tt>" command. This includes the functionality of the Z line as well as a lot of additional functionality.

|-
| dz || The amount by which the elevation has been changed by the Z Line. A positive value indicates that the elevation has been increased by the GIS layer and a negative value indicates that the elevation has been lowered. For example, a value of 0.3 would indicate that elevation point has been raised by 0.3 (metresmeters or feet if running in US Customary units.)
|-
| Elevation (ZExact if SGS is used)|| The elevation afterwithin the zptcell. If SGS is used, the elevation at the exact location of the cell centre, face mid-point, hasor beencell modifiedcorner.
|-
| dZMin (only if SGS is used)|| The change in minimum elevation inside cells, along faces or at corners.
|-
| ZMin (only if SGS is used)|| The minimum elevation within the cell.
|-
| Source || The path to the GIS layer which has caused the elevation point to be modified.

'''Note: ''' moreMore than one Z Lineline layer can modify the same elevation point. For example, if two breaklines which intersect are applied which intersect, then the later occurrence in the geometry control file is given preference. In the _zln_zpt check file both modifications are reported. The final elevations are reported in the [[Check_Files_2d_zpt | 2d_zpt check file]].
 
For MapInfo users this layer has a symbology applied, into three styles:
