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

Click on the map to see a callout with the clicked location's coordinate formatted in 4 different ways. You can also put a coordinate string in any of these formats in the text field. Hit Enter and the coordinate string will be parsed to a map location which the callout will move to.

How it works

  1. Get or create a MapPoint with a spatial reference.
  2. Use one of the static "to" methods on CoordinateFormatter such as CoordinateFormatter.ToLatitudeLongitude(point, CoordinateFormatter.LatitudeLongitudeFormat.DecimalDegrees, 4) to get the formatted string.
  3. To go from a formatted string to a Point, use one of the "from" static methods like CoordinateFormatter.FromUtm(coordinateString, map.SpatialReference, CoordinateFormatter.UtmConversionMode.NorthSouthIndicators).
