Identify records with out-of-range geographic coordinates

This function identifies records with out-of-range coordinates (not between -90 and 90 for latitude; between -180 and 180 for longitude).

bdc_coordinates_outOfRange(
  data,
  lat = "decimalLatitude",
  lon = "decimalLongitude"
)

Arguments

data

data.frame. Containing geographical coordinates. Coordinates must be expressed in decimal degrees and WGS84.

lat

character string. The column name with latitude in decimal degree and in WGS84. Default = "decimalLatitude".

lon

character string. The column with longitude in decimal degree and in WGS84. Default = "decimalLongitude".

Value

A data.frame containing the column ".coordinates_outOfRange". Compliant (TRUE) if 'lat' and 'lon' are not out-of-range; otherwise "FALSE".
