Survey comments

Each survey can be assigned a Survey comment. Field technicians can often provide a description of each survey. These comments provide valuable insight into the purpose of a TEST or IVS file. Other times this comment can be used by a field technician to mark a survey to be ignored during processing. Hovering over an entry will show a tooltip with the comment if one exists.
