</div>VerticalExtent can be linked to a VerticalCRS through the<br>
VerticalExtent.getVerticalCRS() method, and the opposite way is possible too<br>
through the VerticalCRS.getExtent() method. But I'm not sure to understand the<br>
issue. You would like to link VerticalExtent to a CompoundCRS rather than<br>
VerticalCRS? Current API do not allows that since the link is rectricted to<br>
VerticalCRS type...</blockquote><div><br>When in my previous email I have expressed my doubt about the SC_CRS meaning, I was indeed talking about this constraint.<br>Row 358 of ISO 19115:2003/Cor.1:2006 provides a role name "verticalCRS" which is associated to a "SC_CRS" domain. So, it isn't possible to use a SC_CompoundCRS or a SC_EngineeringCRS (both are SC_CRS) for the verticalCRS link? I thought that the specification has should explicitly state "SC_VerticalCRS" instead of "SC_CRS". <br>

<br>
However CompoundCRS can be linked to an Extent, and giving an Extent we can<br>
invokes getVerticalElements() for fetching the VerticalExtents, and invoke<br>
getVerticalCRS() on those. Would it be applicable?<br>
