ROV navigation file format
The navigation data files are named following this convention: navYYYYDDDxxxx.txt. For example, the file name for ROV Ventana data collected on 3/10/98 would be nav1998069vnta.txt.
The files are comma-delimited ASCII text files that can be easily imported in applications such as MS Excel and ArcView. The first line of the file provides a shortened name (a "header") for the data field. See the following table for a description of the fields.
