In wpgp/wpUtilities: Data Analysis and Modeling Package from WorldPop

Description

wpRasterize function will transfer values associated with 'object' type spatial data (data.frame) to raster cells. Function is using paralle library to work with a big raster data. The raster file will be splited to blocks and processed per block

Usage

wpRasterize(x, df, cores = NULL, minblk = NULL, NAflag = NULL,
  datatype = NULL, filename = rasterTmpFile(), overwrite = TRUE,
  silent = TRUE)

Arguments

x	Raster* object
df	data.frame of points
cores	number of cores
minblk	Integer. Minimum number of blocks
NAflag	NO data value will be used for a new raster
datatype	Type of raster. Avalible are INT1S/INT2S/INT4S/FLT4S/LOG1S/INT1U/INT2U/INT4U/FLT8S
filename	File of a new raster file.
overwrite	Overwrite existing file
silent	If FALSE then the progress will be shown

Value

Raster* object

Examples

wpRasterize( x=rasterObj, df=df, cores=2,minblk=4,NAflag=-99999,datatype='INT1U' )
