bdc_coordinates_from_locality {bdc}

Identify records lacking or with invalid coordinates but containing locality information

Description

This function Identifies records whose coordinates can potentially be extracted from locality information.

Usage

bdc_coordinates_from_locality(
  data,
  lat = "decimalLatitude",
  lon = "decimalLongitude",
  locality = "locality",
  save_outputs = FALSE
)

Arguments

data

data.frame. Containing geographical coordinates and the column "locality'.

lat

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

lon

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

locality

character string. The column name with locality information. Default = "locality".

save_outputs

logical. Should a table containing transposed coordinates saved for further inspection? Default = FALSE.

Details

According to DarwinCore terminology, locality refers to "the specific description of the place" where an organism was recorded.

Value

A data.frame containing records missing or with invalid coordinates but with potentially useful locality information. When save_outputs = FALSE the data.frame is saved in Output/Check/01_coordinates_from_locality.csv
