timeVrtProbaV: Build GDAL vrt from probav images

In johanez/probaV: Utils for time-series analysis of Proba-V data

Description

Stacks Proba-V layers into a GDAl virtual file, using gdalbuildvrt. GDAL vrt was found to query faster than raster::stack.

Usage

timeVrtProbaV(x, pattern, stacked_bands = NULL, vrt_name,
  order_chrono = TRUE, tile = NULL, end_date = NULL,
  return_raster = TRUE)

Arguments

x	Character. Directory of a Proba-V geotiffs or list of well formated filenames.
stacked_bands	Character. Which abnds are stacked (typically RADIOMETRY)
vrt_name	Character. Output filename.
tile	Character. Which tile to process. Format: "X00Y00".
end_date	Date. Last date to process.
patttern	Character. As in list.files.
orderChrono	Logical. Wether to oder the stack chronologically. Default TRUE.
retunr_raster	Logical. Weather a RasterBrick should eb returned. Else a info data.frame witht is returned (see getProbaVInfo)

Details

If stacked bands are present, a nested vrt is build.

Value

a rasterBrick pointing to the vrt or a data.frame with meta data.
