CreateGrid: Create a Regularly Spaced SpatialPointsDataFrame

Description

This function creates a regular grid of SpatialPointsDataFrame from the extent of a given sp object and a given resolution.

Usage

CreateGrid(w, resolution)

Arguments

w

sp object; the spatial extent of this object is used to create the regular SpatialPointsDataFrame.

resolution

numeric; resolution of the grid (in map units). If resolution is not set, the grid will contain around 7500 points. (optional)

Value

The output of the function is a SpatialPointsDataFrame of regularly spaced points with the same extent as w.
