Show coordinates in multiple formats

Format coordinates in a variety of common notations.

Use case

The coordinate formatter can format a map location in WGS84 in a number of common coordinate notations. Parsing one of these formats to a location is also supported. Formats include decimal degrees; degrees, minutes, seconds; Universal Transverse Mercator (UTM), and United States National Grid (USNG).

How to use the sample

Tap on the map to see the text fields update with the tapped location’s coordinates formatted in 4 different ways. You can also put a coordinate string in the corresponding text field. Tap return and the coordinate string will be parsed to a map location which will move the map point and update the other text fields’ coordinate strings.

How it works

1. Get or create a map Point with a spatial reference.
2. To get the formatted string, use one of the static methods below.
   • class CoordinateFormatter.latitudeLongitudeString(from:format:decimalPlaces:)
   • class CoordinateFormatter.utmString(from:conversionMode:addSpaces:)
   • class CoordinateFormatter.usngString(from:precision:addSpaces:)
3. To get an Point from a formatted string, use one of the static methods below.
   • class CoordinateFormatter.point(fromLatitudeLongitudeString:spatialReference:)
   • class CoordinateFormatter.point(fromUTMString:spatialReference:conversionMode:)
   • class CoordinateFormatter.point(fromUSNGString:spatialReference:)
