This function creates a "file directory" by scanning all available raster files and extracting relevant metadata.
fdir_init(rootdir, filter = c("PK", "SMR", "LK", "TA"))
| rootdir | Character string specifying the directory where the folders are stored |
|---|---|
| filter | Names of the folders to look for. Only folders containing the character strings specified here are included in the search. |
This function scans all folders in the root dirctory corresponding to the folders given by
folders = . It saves this directory in the package environment, and and
can later use this info to determin which rasters to import when running the
command get_raster().
Currently, only files ending with "tif" are checked for extent, number of layers and resolution and other informatin.
Parent folders (subfolders of rootdir =) are scanned non recursively for
raster data with the extention ".tif". These folders must adhere a specific structure:
TYPE_Scale_EPSG_index
TYPEcorresponds to the maptype. IN Switzerland this is typically SMR, PK, LK or TA. Must be followed by a _
Scaledefines the map scale as x in 1:1'000x. Must be followed by a _
EPSGspecifies the CRS of the containing raster data Must be followed by a _ only if name is specified
