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>
1 | Oyster_subincr_area(IncG, subincr_matrix, Xstep)
|
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 |
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)
subincr_matrix |
Revised version of the "incr_matrix" data frame that contains cross section area recalculated for every sub-increment |
