geocode_radii: Geocode Polygon Shapes

In schwarja209/HurricaneWindGeom: Provides Tools to Create a Geom Showing Wind Radii for Hurricane

Description

This function takes a point in space, given by a longitude and latitude, and projects out the outline of a radial polygon originating from the point. The outline it projects is made up of hundreds of additional points. The distance in projects it is based on the radius provided, and the extent of the polygon is determined by the degrees input into the variable "arc". If the radius is in any length of measurement other than meters, please also provide a convertion factor.

Usage

geocode_radii(point, arc = 0:360, radius = 1, conv = 1, scale = 1)

Arguments

point	a numeric vector containing the longitude and latitude of the startin point of a polygon radius
arc	a numeric vector containing the range of degrees over which to draw additional polygon points
radius	a numeric object specifying the length of the radius of a polygon
conv	a numeric object specifying a conversion factor, if the radius is not in meters
scale	a numeric object between 0 and 1, specifying a scale by which to reduce the radius, if any

Value

a data frame of geocoded longitudes and latitude points, specifying the outline of a polygon
