wrapCache {terra}

SpatRaster wrap with caching options

Description

Use wrap to pack a SpatRaster with caching options. See wrap for the general approach that is easier and better to use in most cases.

This method allows for specifying a folder, or filenames, to cache all sources of a SpatRaster in a specific location (on disk).

Usage

## S4 method for signature 'SpatRaster'
wrapCache(x, filename=NULL, path=NULL, overwrite=FALSE, ...)

Arguments

x

SpatRaster

filename

character. A single filename, or one filename per SpatRaster data source. If not NULL, the raster sources are saved in these files

path

character. If not NULL, the path where raster sources will be saved. Ignored if filenames is not NULL

overwrite
