dem.displacement.mapping: 3D DEM displacement mapping from BUnwarpJ

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

Description

Perform 3D displacement mapping from DEMs using raw BUnwarpJ transformation file

Usage

dem.displacement.mapping(tx_file, r_source, r_target, is_inverse = FALSE)

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.
is_inverse	(logical) TRUE if image registraiton performed in the inverse direction, otherwise FALSE.

Value

Returns a data frame containing the following columns:

x_source & y_source	x & y coordinates from a CRS for the registration
z_source	the elevation value (intensity) corresponding the source locations
x_target & y_target	x & y coordinates from a CRS representing the x & y transformation for every location in the source image
z_target	the elevation value (intensity) corresponding the target locations (from the target image /elevation model)
x_disp	x displacement of registered image (from source image)
y_disp	y displacement of registered image (from source image)
z_disp	z displacement of registered image (from source image) (z_target - z_source)
xy_disp	magnitude of the displacement in 2D (xy)
xyz_disp	magnitude of the displacement in 3D (xyz)
aspect	geographic orientation of vector direction with 0 degrees being due north and 90 degrees being due east
slope	angle in degrees of displacement in z direction
