Use case

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

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 DEGREES_MINUTES_SECONDS.
  5. To set the grid, use the setGrid(grid) method on the map view.
