<br>
no expert here on my side, though, from the manual:<br>
<br>
skip=integer<br>
Number of cells between flowlines<br>
<br>
Another option, skip, indicates that only the flowlines from every val-th<br>
cell are to be included in flowline. <br>
<br>
=> it may be something like: val-th value is the threshold value given by<br>
skip<br>
<br>
The default skip is max(1, <rows in elevation>/50, <cols in elevation>/50)<br>
<br>
=> it's the calculation of the default skip value if no skip=integer figure<br>
is given.<br>
<br>
see the r.mapcalc manual:<br>
<a href="https://grass.osgeo.org/grass78/manuals/r.mapcalc.html" rel="noreferrer" target="_blank">https://grass.osgeo.org/grass78/manuals/r.mapcalc.html</a><br>
<br>
max(x,y[,z...]) largest value of those listed <br>
<br>
contribution for precising the manual welcome.<br>
<br>
<br>
