Oyster_subincr_area: Formula that calculates area between sub-increments
Description
Formula that calculates cross section area between each sub-increment and
the previous sub-increment.
de Winter, N. J. (2017) <doi:10.5194/gmd-2017-137>
Usage
Oyster_subincr_area(IncG, subincr_matrix, Xstep)
Arguments
IncG
Matrix of X- and Y-coordinates of all interpolated sub-increments
subincr_matrix
Data frame that contains characteristics of every
sub-increment
Xstep
Step value in X-direction for the interpolation of sub-increments
Value
subincr_matrix
Revised version of the "incr_matrix" data frame that
contains cross section area recalculated for every sub-increment
Details
Areas between sub-increments are calculated by averaging the difference
in Y-values between sub-increments and multiplying them with the step in X-values
(dx)
