Field used for natural science collections


  • This field indicates the longitude or meridian of the collection site.


  • N.B.: Separate records must be made for similar specimens from different longitudes.

Entry rules:

  1. The data in the Longitude field must always be recorded as a series of seven digits, followed by a space and the letter "E" or "W". Enter the data as follows: DDD MM ss (D for "degree", M for "minute" and s for "second"), a space and the direction (E for East and W for West).

  2. Zero-fill partial longitude data to seven digits.

  3. If you are unsure whether your information is correct, include a space and a question mark after the longitude.
  4. If you do not know the exact longitude of the collection site but know that it was between two longitudes, enter the first longitude, a semicolon, a space and the second longitude. Make a note in the Habitat/Locality Remarks field that the figure is an interval.
