In rLakeHabitat: Interpolate Bathymetry and Quantify Physical Aquatic Habitat

Contour Lines to Points

Description

Get point coordinates and depth values along predetermined contours at a specified density.

Usage

contourPoints(object, depths = NULL, geometry = "geometry", density = 10)

Arguments

object	polygon or multipolygon shapefile (.shp) with depths included as an attribute column. Can be an sf or spatVector object.
depths	character string describing column name of depth attribute
geometry	character string describing column name of geometries. Default = "geometry"
density	numeric value describing distance between points in meters, default = 10m

Value

dataframe of coordinates and associated depths
