This template creates a bottom note which explains that VERTCON, an online orthometric height conversion tool, was used to calculate the NAVD 88 elevation from the NGVD 29 elevation. Ref tags are generated by the template and so must not be added by the editor.
Usage
The NGVD 29 elevation and the NAVD 88 the must be specified using either feet or meters. A ref name and a ref group name can be specified if needed. See WP:REFNAME and WP:REFGROUP.

- {{VERTCON |ngvd29_ft= |navd88_ft= |name="name" |group="group"}}
