rstarspan: Extracts raster data at vector locations.

In STARStools: R functions for working spatial/remote sensing data.

Description

Extracts raster data at vector locations.

Usage

  rstarspan(vectors, rasters,
    outformat = "SpatialDataFrame", borderx = 0,
    bordery = 0, force_window_odd = TRUE,
    miniraster_direction = "vertical",
    miniraster_vector = TRUE, verbose = TRUE, ...)

Arguments

vectors	a vector of superclass "Spatial" or a list of vectors.
rasters	a raster of superclass "Raster" or a list of rasters.
outformat	Character. Can be "SpatialDataFrame" (appends the extracted data to the original Spatial* object) or "DataFrame" (only returns the data.frame portion).
...	See ?extract for parameters (e.g. "fun") that can be used.
borderx	TODO
bordery	TODO
force_window_odd	TODO
miniraster_direction	TODO
miniraster_vector	TODO
verbose	TODO

Note

If the input vector(s) are SpatialPolygonsDataFrame, the user must assign "fun" if outformat="SpatialDataFrame".
