RasterMoransI

case class RasterMoransI(r: Op[Raster], n: Op[Neighborhood], tns: Op[TileNeighbors]) extends FocalOp[Raster] with Product with Serializable

Calculates spatial autocorrelation of cells based on the similarity to neighboring values.

The statistic for each focus in the resulting raster is such that the more positive the number, the greater the similarity between the focus value and it's neighboring values, and the more negative the number, the more dissimilar the focus value is with it's neighboring values.

r

Raster to perform the operation on.

n

Neighborhood to use in this focal operation.

tns

TileNeighbors that describe the neighboring tiles.

Note

Since mean and standard deviation are based off of an Int based Histogram, those values will come from rounded values of a double typed Raster (TypeFloat,TypeDouble).

,

This operation requires that the whole raster be passed in; it does not work over tiles.

18. def getCalculation(r: Raster, n: Neighborhood): FocalCalculation[Raster] with Initialization

Gets a calculation to be used with this focal operation for the given raster neighborhood.

Gets a calculation to be used with this focal operation for the given raster neighborhood.

Choosing the calculation based on on the raster and neighborhood allows flexibility in what calculation to use; if some calculations are faster for some neighborhoods (e.g., using a CellwiseCalculation for Square neighborhoods and a CursorCalculation for all other neighborhoods), or if you want to change the calculation based on the raster's data type, you can do so by returning the correct FocalCalculation from this function.

r

Raster that the focal calculation will run against.

n

Neighborhood that will be used in the focal operation.
