isSpatial: Transform to Simple Feature Polygons

In windfarmGA: Genetic Algorithm for Wind Farm Layout Optimization

Transform to Simple Feature Polygons

Description

Helper Function, which transforms SpatialPolygons or coordinates in matrix/data.frame - form to a Simple Feature Polygon

Usage

isSpatial(shape, proj)

Arguments

shape	An area as SpatialPolygon, SimpleFeature Polygon or coordinates as matrix/data.frame
proj	Which Projection should be assigned to matrix / data.frame coordinates

Details

If the columns are named, it will look for common abbreviation to match x/y or long/lat columns. If the columns are not named, the first 2 numeric columns are taken.

Value

A Simple Feature Polygon

Examples

library(sf)
df <- rbind(
  c(4498482, 2668272), c(4498482, 2669343),
