no expert here on my side, though, from the manual: skip=integer Number of cells between flowlines Another option, skip, indicates that only the flowlines from every val-th cell are to be included in flowline. => it may be something like: val-th value is the threshold value given by skip The default skip is max(1, <rows in elevation>/50, <cols in elevation>/50) => it's the calculation of the default skip value if no skip=integer figure is given. see the r.mapcalc manual: https://grass.osgeo.org/grass78/manuals/r.mapcalc.html max(x,y[,z...]) largest value of those listed contribution for precising the manual welcome. ----- best regards Helmut -- Sent from: http://osgeo-org.1560.x6.nabble.com/Grass-Users-f3884509.html _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
