angles: Angles

In ragram: Radargrammetry

Description

Returns angles provided by GCPs/TPs as a SpatialPointsDataFrame object.

Usage

angles(object, z = "thetaIn", interpolate = F, variogram.fit = T,
  plot.fit = F, aggregate = T, aggregate.fact = 1000, ...)

## S4 method for signature 'GeolocationPoints'
angles(object, z = "thetaIn", interpolate = F,
  variogram.fit = T, plot.fit = F, aggregate = T, aggregate.fact = 1000,
  ...)

## S4 method for signature 'SAR'
angles(object, z = "thetaIn", interpolate = F,
  variogram.fit = T, plot.fit = F, aggregate = T, aggregate.fact = 1000,
  ...)

## S4 method for signature 'SARSet'
angles(object, z = "thetaIn", interpolate = F,
  variogram.fit = T, plot.fit = F, aggregate = T, aggregate.fact = 1000,
  ...)

Arguments

object	Object of the SAR-class or a subclass (e.g. Sentinel-class or TSX-class).
z	Character. either incidence ('thetaIn', default) or elevation angles 'thetaEl'.
interpolate	Logical. Interpolate angles?
variogram.fit	Logical. Fit a Gaussian variogram?
plot.fit	Logical. Plot the fitted variogram?
aggregate	Logical. Should the raster be aggregated? If no aggregation is done the interpolation might take a very long time.
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).

Value

SpatialPointsDataFrame
