plotSAR: Plot SAR record

In ragram: Radargrammetry

Description

Plot one SAR or two SAR records together.

Usage

plotSAR(object, slave = NULL, xlab = "Longitude", ylab = "Latitude",
  maxpixels = 50000, max.val = 500, cex.axis = 1, cex.lab = 1,
  legend.by = 30, plotIntersect = T, border = "red", grid = T,
  plot.legend = T, legend.lab = "Amplitude", legend.line = 2.2,
  breaks = seq(0, max.val, by = 1), legend.breaks = seq(0, max.val, by =
  legend.by), zlim = c(0, max.val), cols = colorRampPalette(c("grey0",
  "grey100"))(length(seq(0, max.val, by = 1)) - 1), north.arrow = F,
  north.arrow.pos = NULL, north.arrow.length = 0.05, scalebar = F,
  scalebar.pos = NULL, scalebar.col = "black", scalebar.d = 100, ...)

Arguments

object	object of the SAR-class or a subclass (e.g. Sentinel-class or TSX-class) (or an object of the SARSet-class, then slave is ignored).
slave	object of the SAR-class or a subclass (e.g. Sentinel-class or TSX-class).
xlab	title of the x axis.
ylab	title of the y axis.
maxpixels	Maximum number of cells to use for the plot (see plot for RasterLayer object).
max.val	maximal amplitude to plot, higher amplitudes are ploted in white. To use even the highest amplitudes type 'object@data@max'.
cex.axis	Numeric. Size of axes.
cex.lab	Numeric. Size of label text.
legend.by	Numeric. Size of legend intervals.
plotIntersect	logical. Plot the intersection area?
border	color of the border.
grid	logical. Add a grid to the plot?
plot.legend	Logical. Plot the legend?
legend.lab	Character. Legend label.
legend.line	Numeric. Distance between legend and label.
breaks	Integer vector. Where to break color bar.
legend.breaks	Integer vector. Where to locate legend ticks.
zlim	Numeric vector of length 2, giving the z coordinate range. Range of values that are plotted.
cols	color ramp (see colorRampPalette).
north.arrow	logical. Plot a north arrow?
north.arrow.pos	vector c(x,y) that contains the position of the north arrow.
north.arrow.length	length of the north arrow.
scalebar	logical. Plot a scalebar?
scalebar.pos	vector c(x,y) that contains the position of the scalebar.
scalebar.col	color of the scalebar.
scalebar.d	distance in kilometers.
...	plotting parameters like xlim, ylim and asp.
xlim	Numeric vector of length 2, giving the x coordinate range.
ylim	Numeric vector of length 2, giving the y coordinate range.
asp	Numeric vector. Aspect, if latitude-longitude coordinates: 1/cos((mean(range(ylim)) * pi)/180).
x	Object of SARSet-class.
y	NULL
