calcgrad: Calculate gradient between two points on stream

In trevorjwilli/streamgradientR: Calculates stream gradient using spatial points, lines, and a DEM

Description

Calculate gradient between two points on stream

Usage

calcgrad(points, ras, fctr)

Arguments

points	Data Frame, output from getupdown function or same format as output from getupdown function
ras	Raster of DEM. Works best if it is in the same projection as original points and lines shapefiles used to calculate the stationing.
fctr	Factor to multiply the segment length by. For example, if lengths are in meters and you want gradient in meters/km fctr must be 0.001

Details

Calculates the stream gradient of segments on a line delimited by an upstream and downstream point. This function works best if the points input is directly used from the output of the getupdown function.
