R Documentation

Create raster giving the establishment likelihoods relating to ports.

Description

Creates spatial port establishment likelihood raster as a function of port container volumes and distance from port.

Usage

port_weights(template_raster, port_data, beta, outfile, return_rast = FALSE)

Arguments

`template_raster`	A `RasterLayer` or path to supported raster file.
`port_data`	Character. Path to csv file containing port container volumes and named Latitude and Longitude (in WGS84) for each port of interest.
`beta`	Numeric. The beta coefficient exponential function of how risk changes with distance from port. beta should be in units per 1km.
`outfile`	Character. Output raster file path. Directory will be created if it does not exist.If not provided, object will be returned to R.
`return_rast`	Logical. Should the resulting raster be returned to R? Ignored if `outfile` is not provided.

Value

If outfile is specified, the resulting raster is saved as a geotiff to that path. If return_rast is TRUE or outfile is not specified the resulting raster is returned, otherwise NULL is returned invisibly.
