Prepare Equal-Area or Equidistant Projection
1 2 3 | LAEA_projection(occurrences = NULL, spatial_object = NULL)
AED_projection(occurrences = NULL, spatial_object = NULL)
|
occurrences |
matrix or data.frame containing coordinates to serve as a reference for the center of the projection. Columns must be: "longitude" and "latitude", in that order. |
spatial_object |
Spatial* objects, Points or Polygons, to be used to calculate a reference for the center of the projection. Projection must be WGS84 (EPSG:4326). |
If arguments are not defined projection is centered in 0, 0 for longitude and latitude.
An object of class CRS.
