st_mesh: Calculate the effective mesh size

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

Calculate the effective mesh size

Description

This function calculates the effective mesh size.

Usage

st_mesh(geom.frag, geom.boundary = NULL, total.area = NULL,
  conv = 10000, do.preProcessing = TRUE, return.geom = FALSE,
  quiet = TRUE)

Arguments

geom.frag	polygon of class sf representing the fragmentation geometry
geom.boundary	polygon of class sf representing subregions, e.g. administrative boundaries
total.area	Numeric value representing size for area. Only to use if geom.boundary is not present. Value must match with the conversion constant c (default hectare). Default: NULL
conv	constant to convert original square m output. Default: 10000 to convert to hectare. If set to 1, than meter square is the result.
do.preProcessing	If TRUE (default), the input of geom.frag is, first, dissolved to single part feature, and second, splitted to multi-parts. By this step it is assured, that polygon connected to each other are summarized
return.geom	If set to TRUE, intermediate geometries are returned as well. Default: FALSE
quiet	If set to FALSE, actual state is printed to console. Default: TRUE.

Value

Vector with shape index and interior edge ratio values
