SAR-class: Synthetic aperture radar (SAR) class

In ragram: Radargrammetry

Description

A class to handle synthetic aperture radar (SAR) data. This class inherits from the RasterLayer-class class of the raster package.

Slots

address

Character. Address of the SAR data main folder.

polarization

Character. Polarization of the SAR record (e.g. VV or HH).

geolocationPoints

GeolocationPoints-class object that contains GCPs/TPs.

node

Character. Direction of the satellite (ascending or descending).

orbit

Integer. Orbit number (e.g. sentinel has 175 in total).

imgSubstring

Character. This substring is searched for when image data is read.

# alternatively
