Helper Function, which transforms SpatialPolygons or coordinates in matrix/data.frame - form to a Simple Feature Polygon
1 |
shape |
An area as SpatialPolygon, SimpleFeature Polygon or coordinates as matrix/data.frame |
proj |
Which Projection should be assigned to matrix / data.frame coordinates |
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.
