sarRecord: Create a synthetic aperture radar (SAR) object

In ragram: Radargrammetry

Description

Creates a synthetic aperture radar (SAR) object. The input is either an existing raster or the folder address of satellite data.

Usage

sarRecord(object, satellite = "", imgSubstring = "", polarization = NULL,
  ...)

## S4 method for signature 'RasterLayer'
sarRecord(object, satellite = "", imgSubstring = "",
  polarization = NULL, ...)

## S4 method for signature 'character'
sarRecord(object, satellite = "", imgSubstring = "",
  polarization = NULL, ...)

## S4 method for signature 'missing'
sarRecord(object, satellite = "", imgSubstring = "",
  polarization = NULL, ...)

Arguments

object	either a character given the folder address of satellite data or a RasterLayer object.
satellite	Character. Either 'sentinel-1' or 'terrasar-x'.
imgSubstring	Character. This substring is searched for when image data is read.
polarization	Character. E.g.'vv' or 'hh'. If the polarization is not given it will be determined from metadata.
...	Further arguments to the constructor of the SAR-class or a subclass.

Value

object of SAR class or subclass that is a well a RasterLayer object.
