I have two sets of data that I need help with
Data from my levelogger in the field takes measurements every 14 minutes
so I have times like
12:00
12:14
12:28

my other data set is NOAA's tidal data, which gives tells me if the tide is higher high (HH), high (H), low (L), or Lower Low (LL) along with the time of day that it reaches that particular tidal height, so I have things that basically tell me:
from 12 to 1 the tide is HH
from 1 to 2 it is L

the times dont match up between the data points.

My question is: Is there an easy way to tell which of my logger points are HH,H,L, or LL without manually looking at each change in tide from NOAA data entering the data???
