ee.Algorithms.CrossCorrelation

Gives information on the quality of image registration between two (theoretically) co-registered images. The input is two images with the same number of bands. This function outputs an image composed of four bands of information. The first three are distances: the deltaX, deltaY, and the Euclidean distance for each pixel in imageA to the pixel which has the highest corresponding correlation coefficient in imageB. The fourth band is the value of the correlation coefficient for that pixel [-1 : +1].

Usage	Returns

If the test fails at any single location in the search region, the ouput pixel for which the correlation is being computed is considered invalid, and will be masked.

Any cluster that spans a cell or tile boundary may receive two different labels in the two halves. Any input pixels with partial masks are fully masked in the output. This algorithm is only expected to perform well for images with a narrow dynamic range (i.e. bytes or shorts).

See: G. Hamerly and C. Elkan. 'Learning the k in k-means'. NIPS, 2003.

Argument	Type	Details

ee.Algorithms.Landsat.pathRowLimit

Limits requests to an ImageCollection of Landsat scenes to return a controllable number of the best scenes for each request. This is intended for use with statistical algorithms like median composites that need a certain amount of good data to perform well, but that do not benefit substantially from additional data beyond that while becoming needlessly expensive. The default arguments select approximately one year's worth of good data.

Note that in rare circumstances, when the tile boundary aligns with a Landsat WRS cell bounadry, queries for adjacent tiles may yield conflicting results. This is why it is important that this algorithm only be used with statistical methods that can tolerate these inconsistencies.

Argument	Type	Details
image	Image	The Landsat TOA image to process.

ee.Algorithms.Landsat.simpleComposite

Computes a Landsat TOA composite from a collection of raw Landsat scenes. It applies standard TOA calibration and then assigns a cloud score to each pixel using the SimpleLandsatCloudScore algorithm.

This algorithm also uses the LandsatPathRowLimit algorithm to select only the least-cloudy scenes in regions where more than maxDepth input scenes are available.

Usage	Returns

Argument	Type	Details

ee.Algorithms.TemporalSegmentation.LandTrendr

Landsat-based detection of Trends in Disturbance and Recovery: temporally segments a time-series of images by extracting the spectral trajectories of change over time. The first band of each image is used to find breakpoints, and those breakpoints are used to perform fitting on all subsequent bands. The breakpoints are returned as a 2-D matrix of 4 rows and as many columns as images. The first two rows are the original X and Y values. The third row contains the Y values fitted to the estimated segments, and the 4th row contains a 1 if the corresponding point was used as a segment vertex or 0 if not. Any additional fitted bands are appended as rows in the output. Breakpoint fitting assumes that increasing values represent disturbance and decreasing values represent recovery.

ee.Algorithms.TemporalSegmentation.Verdet

Vegetation Regeneration and Disturbance Estimates through Time, forest change detection algorithm. This algorithm generates a yearly clear-sky composite from satellite imagery, calculates a spectral vegetation index for each pixel in that composite, spatially segments the vegetation index image into patches, temporally divides the time series into differently sloped segments, and then labels those segments as disturbed, stable, or regenerating. Segmentation at both the spatial and temporal steps are performed using total variation regularization.

The output consists of a 1D array per pixel containing the slope of fitted trend lines. Negative values indicate disturbance and positive values regeneration.

ee.Algorithms.Terrain

Calculates slope, aspect, and a simple hillshade from a terrain DEM.

Otherwise the distance is interpereted as meters and the buffering is performed in a spherical coordinate system.

Simplifies the geometry to within a given error margin. Note that this does not respect the error margin requested by the consumer of this algorithm, unless maxError is explicitly specified to be null.

Retrieves the value of this object from the server.

If no callback function is provided, the request is made synchronously. If a callback is provided, the request is made asynchronously.

The asynchronous mode is preferred because the synchronous mode stops all other code (for example, the EE Code Editor UI) while waiting for the server. To make an asynchronous request, evaluate() is preferred over getInfo().

Returns the computed value of this object.

Otherwise the distance is interpereted as meters and the buffering is performed in a spherical coordinate system.

Usage	Returns
ee.Geometry.Rectangle(coords, proj, geodesic, evenOdd)	Geometry.Rectangle

Argument	Type	Details

proj	Projection, optional	The projection of this geometry. If unspecified, the default is the projection of the input ee.Geometry, or EPSG:4326 if there are no ee.Geometry inputs.

evenOdd	Boolean, optional	If true, polygon interiors will be determined by the even/odd rule, where a point is inside if it crosses an odd number of edges to reach a point at infinity. Otherwise polygons use the left- inside rule, where interiors are on the left side of the shell's edges when walking the vertices in the given order. If unspecified, defaults to true.

ee.Geometry.simplify

Simplifies the geometry to within a given error margin. Note that this does not respect the error margin requested by the consumer of this algorithm, unless maxError is explicitly specified to be null.

This overrides the default Earth Engine policy for propagating error margins, so regardless of the geometry accuracy requested from the output, the inputs will be requested with the error margin specified in the arguments to this algorithm. This results in consistent rendering at all zoom levels of a rendered vector map, but at lower zoom levels (i.e. zoomed out), the geometry won't be simplified, which may harm performance.

maxError	ErrorMargin	The maximum amount of error by which the result may differ from the input.

The reducer output names determine the names of the output bands: reducers with multiple inputs will use the output names directly, reducers with a single input and single output will preserve the input band names, and reducers with a single input and multiple outputs will prefix the output name with the input band name (e.g. '10_mean', '10_stdDev', '20_mean', '20_stdDev', etc.).

Reducer input weights will be the product of the input mask and the fraction of the output pixel covered by the input pixel.

Argument	Type	Details
this: image	Image	The image to register.
