parsecoords: Parse coordinates into separate fields

In biogeo: Point Data Quality Assessment and Coordinate Conversion

Description

Parse coordinates into separate fields from a character vector using a format string. This is a manual version of dmsparse.

Usage

parsecoords(dat, d1, fmtstr)

Arguments

dat	a character vector of coordinates
d1	a summary of the various coordinate formats obtained from uniqueformats
fmtstr	a format string for the different formats present e.g. "dd.mm","dd.mm.ss"

Value

a dataframe containing degrees, minutes, seconds, letters (N,S,E,W) and decimal degrees in separate columns

Note

In most cases dmsparse would be preferable
