gs_rasterize: Rasterize polygon layer

In gridsample: Tools for Grid-Based Survey Sampling Design

Description

This function creates a raster layer that adopts values from a defined field in a polygon layer, using rasterize from the raster package. This function also converts values to binary if desired, where all zero values are recorded as zero, and all non-zero values are recorded as one. This function also saves the output raster in the working directory.

Usage

gs_rasterize(input_features, output_raster, template_raster,
  binary = FALSE, field = "ID", overwrite = FALSE,
  format = "GTiff")

Arguments

input_features	SpatialPolygons* object. Name of input shapefile layer. Should be a SpatialPolygons object.
output_raster	Character. Desired name of output raster layer.
template_raster	Raster* object. Raster with desired characteristics (resolution, extent) of output raster.
binary	logical. If TRUE, any non-zero values will be converted to one.
field	character. Name of variable that output raster should inherit.
overwrite	logical. Defines whether to overwrite if output_raster already exists.
format	character. Desired format of output raster file.

Value

Vector of values representing the stratum that occurs most often within a given subset of the raster.
