Geodesic is the default for global collections. To create a planar geometry, set the `geodesic` parameter to `false` in the `ee.Geometry` constructor, as shown in the code example: `var planarPolygon = ee.Geometry(polygon, null, false);`. Conversion between these types is possible using the same constructor. Figure 1 illustrates the visual difference between geodesic (red) and planar (black) polygons.\n"],null,[]]
