latlon

Parse geographic coordinates from string.

A wide range of commonly used formats is supported. See the unit tests for a complete reference.

If a format you need is missing, please submit a merge request (including unit tests).

Usage

```rust // parse a coord let coord : geo::Point = latlon::parse("N 50°5.30385', E 14°26.94732'").unwrap();

// individual lat/lng parsing let lat : f64 = latlon::parselat("N 50°5.30385'").unwrap(); let lng : f64 = latlon::parselng("E 14°26.94732'").unwrap(); ```

Supported formats

Example of supported formats:

• 40° 26' 46" N 79° 58' 56" W
• N 40° 26' 46" W 79° 58' 56"
• 40° 26.767' N 79° 58.933' W
• 40° 26' 46" 79° 58' 56", 40° 26' 46", 79° 58' 56", ...
• N 40° 26.767' W 79° 58.933'
• 40° 26.767' 79° 58.933', 40° 26.767', 79° 58.933', ...
• N 40.446° W 79.982°
• 40.446° N 79.982° W
• 40.446° 79.982°, 40.446,79.982, etc.

Parser rules

• All formats support negative degrees (preceded by a minus sign). Positive latitude is North, positive longitude is East.
• Whitespace is optional and ignored, except for formats that would become unparsable.
• Degree, minute and second symbols can be omitted.
• Comma (,) may be used as an alternate decimal separator.
• Unicode quotes (e.g. ’, ”) are supported for minutes and seconds.
• The two coordinates can be separated by comma (,), semicolon (;), whitespace, or nothing at all, if not ambiguous.
