Description Usage Arguments Details Examples
Extracts cross sections and bankfull width in parallel
1 | extract_xs_wbf(cross_section, depth, hpc = TRUE, h = 20)
|
cross_section |
output from bisect_line_segments() |
depth |
bathymetry raster |
hpc |
flag for "high performance computing" |
h |
minimum width (in pixels) to count a channel |
This is the same as extract_wbf, except that it also outputs the transects and has some error catches. Extracts data underlying the lines in cross_section. Uses first and last overlapped pixels to estimate bankfull width from perpendicular bisectors to the river centerline. For Pool 5, I got an error about raster I/O. I think this is due to a corrupt raster file.
1 2 | wbfs_and_mc <- extract_xs_wbf(cross_section, depth, hpc = TRUE)
wbfs_and_mc <- extract_xs_wbf(cross_section[1:10], depth, hpc = TRUE)
