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
- Get or create a
MapPointwith a spatial reference. - Use one of the static "to" methods on
CoordinateFormattersuch asCoordinateFormatter.ToLatitudeLongitude(point, CoordinateFormatter.LatitudeLongitudeFormat.DecimalDegrees, 4)to get the formatted string. - To go from a formatted string to a
Point, use one of the "from" static methods likeCoordinateFormatter.FromUtm(coordinateString, map.SpatialReference, CoordinateFormatter.UtmConversionMode.NorthSouthIndicators).
