Z coordinate, expressed in the dataset Coordinate Reference System , of the current tie point.

Dimap 1.1 Generic Profile

<TIE_POINT_CRS_Z>

Dimap_Generic 1.0

Description :

Used to provide registration points (tie points) for Tie-Point Geopositioning. Tie points are point positions known in two different coordinate systems : the Coordinate Reference System of the dataset (in most of the cases a projected coord. Sys.) and in the internal, native, data coordinate system (such as rows and columns for raster data).

TIE_POINT_CRS_Z gives the Z coordinate of a tie point in the Coordinate Reference System space. The Z coordinate is often useless but might be useful when Tie points are used to carry GCP information for further geometric physical modelling of the image (case of low-level imagery)

Please refer to the Dimap Documentation about Geopositioning schemes.

Example :
 
<Tie_Point>
  <TIE_POINT_CRS_X unit='M'>103456.0</TIE_POINT_CRS_X>
  <TIE_POINT_CRS_Y unit='M'>1467379.0</TIE_POINT_CRS_Y>
  <TIE_POINT_DATA_X>23.5</TIE_POINT_DATA_X>
  <TIE_POINT_DATA_Y>123.34</TIE_POINT_DATA_Y>
</Tie_Point>
