brick.decimal.formatter: Imports a brick of raster ascii maps into a 'brick' object

Description

Imports a brick of raster ascii maps into a 'brick' object

Usage

brick.decimal.formatter(file = NULL, file_prefix,
    formatter = "%04d", file_extension = ".asc",
    nlayers = 10, use.read.raster.from.url = FALSE,
    crs = NULL, start.from.zero = FALSE)

Arguments

file

fileneme of the 'brick' files containing the decimal formatter. It is NULL by default, otherwise it replaces file_suffix, formatter and file_extension.

file_prefix

character string suffix name of the 'brick' files.

file_extension

strinf value. Default is ".asc"

Examples

library(geotopbricks)
library(raster)
file <- system.file("doc/examples/snowthickness",package="geotopbricks")
file <- paste(file,"SnowThickness0000L%04d.asc",sep="/")
b <- brick.decimal.formatter(file=file,nlayers=15)
nlayers(b)
