createComparableCDL {cdlTools} | R Documentation |
createComparableCDL
uses a base index within a raster list, and sets all other
raster images within the list to the same resolution, projection, and extent. The
raster function resample is used to tranform raster images, therefore this
function may be quite slow without tuning.
createComparableCDL(rasterList, filenames, baseIndex, progress = "")
rasterList |
A list of raster images. |
filenames |
An array of file names of raster images to coerce into a raster list,
if |
baseIndex |
The index of the raster list element that all other elements will match with respect to resolution, projection and extent. |
progress |
A string for the raster progress bar type, default "" is none, "text" provides text output, "window" provides a gui window if available. |
A list of raster images matching in extent, resolution, and projection.
