ee.Image.reduceToVectors

Convert an image to a feature collection by reducing homogeneous regions. Given an image containing a band of labeled segments and zero or more additional bands, runs a reducer over the pixels in each segment producing a feature per segment.

Either the reducer must have one fewer inputs than the image has bands, or it must have a single input and will be repeated for each band.

Usage	Returns
Image.reduceToVectors(reducer, geometry, scale, geometryType, eightConnected, labelProperty, crs, crsTransform, bestEffort, maxPixels, tileScale, geometryInNativeProjection)	FeatureCollection

Argument	Type	Details
this: image	Image	The input image. The first band is expected to be an integer type; adjacent pixels will be in the same segment if they have the same value in this band.
reducer	Reducer, default: null	The reducer to apply. Its inputs will be taken from the image's bands after dropping the first band. Defaults to Reducer.countEvery().
geometry	Geometry, default: null	The region over which to reduce data. Defaults to the footprint of the image's first band.
scale	Float, default: null	A nominal scale in meters of the projection to work in.
geometryType	String, default: "polygon"	How to choose the geometry of each generated feature; one of 'polygon' (a polygon enclosing the pixels in the segment), 'bb' (a rectangle bounding the pixels), or 'centroid' (the centroid of the pixels).
eightConnected	Boolean, default: true	If true, diagonally-connected pixels are considered adjacent; otherwise only pixels that share an edge are.
labelProperty	String, default: "label"	If non-null, the value of the first band will be saved as the specified property of each feature.
crs	Projection, default: null	The projection to work in. If unspecified, the projection of the image's first band is used. If specified in addition to scale, rescaled to the specified scale.
crsTransform	List, default: null	The list of CRS transform values. This is a row-major ordering of the 3x2 transform matrix. This option is mutually exclusive with 'scale', and replaces any transform already set on the projection.
bestEffort	Boolean, default: false	If the polygon would contain too many pixels at the given scale, compute and use a larger scale which would allow the operation to succeed.
maxPixels	Long, default: 10000000	The maximum number of pixels to reduce.
tileScale	Float, default: 1	A scaling factor used to reduce aggregation tile size; using a larger tileScale (e.g., 2 or 4) may enable computations that run out of memory with the default.
geometryInNativeProjection	Boolean, default: false	Create geometries in the pixel projection, rather than EPSG:4326.
