Display grid

This code sample is available for these platforms:
View Sample on GitHub

Display coordinate system grids including Latitude/Longitude, MGRS, UTM and USNG on a map view. Also, toggle label visibility and change the color of grid lines and grid labels.

Image of display grid

Use case

Grids are often used on printed maps, but can also be helpful on digital maps, to identify locations on a map.

How to use the sample

Select type of grid from the types (LatLong, MGRS, UTM and USNG) and modify its properties like label visibility, grid line color, and grid label color. Press the button to apply these settings.

How it works

  1. Create an instance of one of the Grid types.
  2. Grid lines and labels can be styled per grid level with setLineSymbol(gridLevel, lineSymbol) and setTextSymbol(gridLevel, textSymbol) methods on the grid.
  3. The label position can be set with setLabelPosition(labelPosition) method on the grid.
  4. For the LatitudeLongitudeGrid type, you can specify a label format of DecimalDegrees or DegreesMinutesSeconds.
  5. To set the grid, use the setGrid(grid) method on the map view.
