ee.FeatureCollection.style

Draw a vector collection for visualization using a simple style language.

Usage	Returns
FeatureCollection.style(color, pointSize, pointShape, width, fillColor, styleProperty, neighborhood, lineType)	Image

Argument	Type	Details
this: collection	FeatureCollection	The collection to draw.
color	String, default: "black"	A default color (CSS 3.0 color value e.g., 'FF0000' or 'red') to use for drawing the features. Supports opacity (e.g., 'FF000088' for 50% transparent red).
pointSize	Integer, default: 3	The default size in pixels of the point markers.
pointShape	String, default: "circle"	The default shape of the marker to draw at each point location. One of: `circle`, `square`, `diamond`, `cross`, `plus`, `pentagram`, `hexagram`, `triangle`, `triangle_up`, `triangle_down`, `triangle_left`, `triangle_right`, `pentagon`, `hexagon`, `star5`, `star6`. This argument also supports these Matlab marker abbreviations: `o`, `s`, `d`, `x`, `+`, `p`, `h`, `^`, `v`, `<`, `>`.
width	Float, default: 2	The default line width for lines and outlines for polygons and point shapes.
fillColor	String, default: null	The color for filling polygons and point shapes. Defaults to 'color' at 0.66 opacity.
styleProperty	String, default: null	A per-feature property expected to contain a dictionary. Values in the dictionary override any default values for that feature.
neighborhood	Integer, default: 5	If styleProperty is used and any feature has a pointSize or width larger than the defaults, tiling artifacts can occur. Specifies the maximum neighborhood (pointSize + width) needed for any feature.
lineType	String, default: "solid"	The default line style for lines and outlines of polygons and point shapes. Defaults to 'solid'. One of: solid, dotted, dashed.

Examples

// FeatureCollection of power plants in Belgium.
var fc = ee.FeatureCollection('WRI/GPPD/power_plants')
            .filter('country_lg == "Belgium"');

// Paint FeatureCollection to an image using collection-wide style arguments.
var fcVis = fc.style({
  color: '1e90ff',
  width: 2,
  fillColor: 'ff475788',  // with alpha set for partial transparency
  lineType: 'dotted',
  pointSize: 10,
  pointShape: 'circle'
});

// Display the FeatureCollection visualization (ee.Image) on the map.
Map.setCenter(4.326, 50.919, 9);
Map.addLayer(fcVis, null, 'Collection-wide style');

// Paint FeatureCollection to an image using feature-specific style arguments.
// A dictionary of style properties per power plant fuel type.
var fuelStyles = ee.Dictionary({
  Wind: {color: 'blue', pointSize: 5, pointShape: 'circle'},
  Gas: {color: 'yellow', pointSize: 6, pointShape: 'square'},
  Oil: {color: 'green', pointSize: 3, pointShape: 'diamond'},
  Coal: {color: 'red', pointSize: 3, pointShape: 'cross'},
  Hydro: {color: 'brown', pointSize: 3, pointShape: 'star5'},
  Biomass: {color: 'orange', pointSize: 4, pointShape: 'triangle'},
  Nuclear: {color: 'purple', pointSize: 6, pointShape: 'hexagram'},
});

// Add feature-specific style properties to each feature based on fuel type.
fc = fc.map(function(feature) {
  return feature.set('style', fuelStyles.get(feature.get('fuel1')));
});

// Style the FeatureCollection according to each feature's "style" property.
var fcVisCustom = fc.style({
  styleProperty: 'style',
  neighborhood: 8  // maximum "pointSize" + "width" among features
});

// Display the FeatureCollection visualization (ee.Image) on the map.
Map.addLayer(fcVisCustom, null, 'Feature-specific style');
