In igapfill: Interface for Gap-Filling Earth Observation Datasets

Console-based application to sort and split spatio-temporal chunks of images

Description

An application of split_replace to split/divide/configure images in parts to which a subsequent call of applyGapfill can be easily handled by regular computer systems.

Usage

sort_split(path, startYear, endYear, nrow_split, ncol_split)

Arguments

path	character with full path name to a directory containing a set of files to be split.
startYear	numeric indicating the starting time-point, on the annual scale, of a time series of satellite images.
endYear	numeric indicating the ending time-point, on the annual scale, of a time series of satellite images.
nrow_split	numeric, in how many equal parts the images' rows must be split? See Details.
ncol_split	numeric, in how many equal parts the images' cols must be split? See Details.

Details

This function asks the user a series of inputs on-the-fly. Should the user allow it, these inputs will be used as arguments in a subsequent call to split_replace.

create_dirs defines a specific directory structure used by sort_split, hence, it is highly recommended to use create_dirs in advance. Also, it is highly recommended to use sort_split before using applyGapfill.

Value

When the user decides not to proceed with this function, a NULL is returned at the console. Otherwise, the resulting splits (.tif files) will be saved at the sub-directories defined by paste0(path, "/gapfill/splits") and a corresponding final _invisible_ message is displayed at the console.

Note

The "sort" part of the function means that in case that the file list created from path is not originally ordered, then sort_split will sort it out internally.
