read.bunwarpj.displacements: 2D image displacement mapping from BUnwarpJ

In jngtz/map.displ.r: Processing ImageJ/Fiji BUnwarpJ Plugin's Image Registration Results for Mapping Surface Displacement

Description

Perform 2D displacement mapping from raster images (or DEMs) using raw BUnwarpJ transformation file

Usage

read.bunwarpj.displacements(tx_file, r_source, r_target)

Arguments

tx_file	The raw transformation file (.txt) from BUnwarpJ.
r_source	The DEM raster filename used as source for image registration.
r_target	The DEM raster filename used as target for image registration.

Value

Returns a data frame containing the following columns:

x_source & y_source	x & y coordinates from a CRS for the registration
x_target & y_target	x & y coordinates from a CRS representing the x & y transformation for every location in the source image
x_disp	x displacement of registered image (from source image)
y_disp	y displacement of registered image (from source image)
xy_disp	magnitude of the displacement in 2D (xy)
aspect	geographic orientation of vector direction with 0 degrees being due north and 90 degrees being due east
