st_integration_index: Calculate integration index

In ggRaver/Lslide: Functions for object-oriented image analysis in landslide science

Calculate integration index

Description

This function calculates an index defining the intergration of new land use area into conisting land use area of the same land use class conisdering two different time steps.

Usage

st_integration_index(geom.old, geom.new, geom.boundary = NULL,
  tol = 0.1, precision = 0, ignr.overlap = FALSE, env.rsaga = NULL,
  use.saga = FALSE, return.geom = FALSE, quiet = FALSE)

Arguments

geom.old	object of class sf representing a land use class of a previous time step
geom.new	object of class sf representing a land use class of a following time step
geom.boundary	polygon of class sf representing subregions, e.g. administrative boundaries
tol	tolerance value for overlapping area m square
precision	precision for process. See sf::st_set_precision(). Default: 0
env.rsaga	environment of SAGA GIS. If st_erase fails then SAGA GIS erase is used. Default: NULL, but in function call if not set: RSAGA::rsaga.env()
use.saga	use SAGA GIS for erase process. Default: FALSE
return.geom	If set to TRUE, intermediate geometries are returned as well. Default: FALSE
quiet	show output on console. Default: FALSE

Value

Vector with integration index (completly integrated: 2/3 < R < 1; good integrated: 1/3 < R < 2/3; low integrated: 0 < R < 1/3; not integrated: 0)
