Tides is one of several ecological settings variables that collectively characterize the biophysical setting of each 30 m cell at a given point in time (McGarigal et al 2017). Tides estimates the probability that a point is intertidal or subtidal. It is derived from a logistic regression model using tide range and elevation to distinguish mapped salt marshes from uplands.
