ee.FeatureCollection.draw
Stay organized with collections
Save and categorize content based on your preferences.
Paints a vector collection for visualization. Not intended for use as input to other algorithms.
| Usage | Returns | FeatureCollection.draw(color, pointRadius, strokeWidth) | Image |
| Argument | Type | Details | this: collection | FeatureCollection | The collection to draw. |
color | String | A hex string in the format RRGGBB specifying the color to use for drawing the features. |
pointRadius | Integer, default: 3 | The radius in pixels of the point markers. |
strokeWidth | Integer, default: 2 | The width in pixels of lines and polygon borders. |
Examples
Code Editor (JavaScript)
// FeatureCollection of power plants in Belgium.
var fc = ee.FeatureCollection('WRI/GPPD/power_plants')
.filter('country_lg == "Belgium"');
// Paint FeatureCollection to an image for visualization.
var fcVis = fc.draw({color: '800080', pointRadius: 5, strokeWidth: 3});
Map.setCenter(4.56, 50.78, 8);
Map.addLayer(fcVis);
Python setup
See the
Python Environment page for information on the Python API and using
geemap for interactive development.
