Description
This function is based on the function shotGroups::getMinCircle() that uses
the Skyum algorithm based on the convex hull. http://www.cs.au.dk/~gerth/slides/sven14.pdf
Usage
1
makeCircle(spdf, crs = NULL)
Arguments
spdf
an object of class ‘sf’ or ‘SpatialPointsDataFrame’
with defined CRS.
crs
a number defining a projected CRS. It is very important
that the selected CRS is accurate in the study area. This is not the CRS for
the argument 'spdf' which should be defined internally. This is the CRS used to
make a flat circle. Some UTM variant is recommended. See getUTMproj
Value
a polygon object of class ‘sf’ with geodesic
coordinates in WGS84 (ESPG:4326).
