In MagicForrest/DGVMTools: DGVM Processing, Analysis and Plotting Tools

Make SpatialPixelDataFrame from a data.table

Description

Converts a data.table (or data.frame) to a SpatialPixelsDataFrame, using the columns "Lon and "Lat" to provide the spatial information. Mostly is called by promoteToRaster, but can be useful in and of itself.

Usage

makeSPDFfromDT(
  input.data,
  layers = "all",
  tolerance = 0.01,
  grid.topology = NULL
)

Arguments

input.data	data.table or data.frame, with columns "Lon" and "Lat" which specify the spatial data
layers	The columns to be selected included in the final SpatialPixelsDataFrame object. Use NULL or "all" if all layers are required.
tolerance	Tolerance (in fraction of gridcell size) for unevenly spaced lon and lats
grid.topology	A GridTopology defining the grid topology for the SpatialPixelsDataFrame object

Value

A SpatialPixelDataFrame
