Create a feature list from raster files

This function generates a feature list from raster files in a specified directory, adding optional attributes to the list based on user-defined parameters. The resulting feature list is written to a text file. Supported raster formats include GeoTIFF (.tif, .tiff), ERDAS Imagine (.img), and ASCII Grid (.asc).

Usage

feature_list(spp_file_dir, weight = NULL, group = NULL, threshold = NULL)

Arguments

spp_file_dir

A character string specifying the directory containing the raster files.

weight

An optional numeric vector (float) to assign weights to the features in the list.

group

An optional integer vector (int) representing the output group number for each raster.

threshold

An optional numeric vector (float) representing threshold values for each raster. If thresholding is applied, values in the input raster below the threshold are set to zero. Layers that contain only zeros after thresholding are removed from the analysis.

Value

A text file containing a feature list of rasters along with any additional attributes specified by the user.
