tgrass: read or write tgrass (time-enabled grass) files

In spacetime: Classes and Methods for Spatio-Temporal Data

read or write tgrass (time-enabled grass) files

Description

read or write tgrass (time-enabled grass) files

Usage

 
read.tgrass(fname, localName = TRUE, useTempDir = TRUE, isGeoTiff = TRUE)
write.tgrass(obj, fname, ...)

Arguments

fname	file name to read from, or write to
localName	logical; if TRUE, fname is a local file, else it is a the full path name to the file
useTempDir	logical: use a temporary directory for extraction?
isGeoTiff	logical: are the files in the tar.gz file GeoTIFFs?
obj	object to export, of class STFDF or RasterStack
...	arguments passed on to writeRaster

Details

The tgrass format is a gzip'ed tar file (.tar.gz) that has geotiff files (with suffix .tif), and three files (list.txt, proj.txt and init.txt) describing the file names and time slices, coordinate reference system, and dimensions

Value

read.tgrass returns an object of class RasterStack, writegrass returns nothing
