disparityMapExpected: Expected (theoretical) disparity between two SAR records

In ragram: Radargrammetry

Description

Returns the expected disparity within the intersection area of two SAR records. Uses the angles provided by GCPs/TPs of both records. The angles for the slave image are interpolated using Kriging (krige). Returns the results as a SpatialPointsDataFrame object.

Usage

disparityMapExpected(object, slave, h = 1, z = "thetaIn",
  variogram.fit = T, plot.fit = F, interpolate = F,
  aggregate.fact = 1000, ...)

Arguments

object	Object of the SAR-class or a subclass (e.g. Sentinel-class or TSX-class).
slave	Object of the SAR-class or a subclass (e.g. Sentinel-class or TSX-class).
h	Numeric. Relative height.
z	Character. Either incidence ('thetaIn', default) or elevation angles 'thetaEl'.
variogram.fit	Logical. Fit a Gaussian variogram?
plot.fit	Logical. Plot the fitted variogram?
interpolate	Logical. Interpolate angles?
aggregate.fact	Integer. Aggregation factor expressed as number of cells in each direction (horizontally and vertically). Or two integers (horizontal and vertical aggregation factor) or three integers (when also aggregating over layers). See aggregate method of raster package.
...	Further arguments (ignored).
