Append positions

Description

Positions are centroids of areas. For oddly shaped (concave) areas, this can have unintended effects. The centroid may for instance lie outside the area.

  areaPolygons,
  areaName,
  latColName,
  lonColName,
  StratumName = "StratumName"
)

areaName	name of column that identifies the area in 'table'
latColName	name of the latitdue column to be appended to 'table'
lonColName	name of the longitude column to be appended to 'table'
StratumName	name of the column in 'areaPolygons' that identifies the area.

Value

'table' with the positions appended in the columns 'latColName' and 'lonColName'.
