Process a group of fields

Description

This function calls other functions of the library to perform interpolation over different fields.

Usage

guinterp_process(
  inputpts,
  inlayer,
  filtered = TRUE,
  id_fieldname = "idfield",
  interp_dir = tempdir(),
  out_path = tempfile(),
  interp_method = "krige",
  smooth = TRUE,
  interp_res = 5,
  out_crs = NA,
  grid_offset = c(0, 0),
  samplesize = 10000,
  samplescheme = "random",
  buffer_radius = 15,
  parallel = TRUE,
  vgm = NA,
  v_nmax = Inf,
  v_maxdist = Inf,
  merge = TRUE,
  overwrite = TRUE,
  .shiny_session = NULL,
  .shiny_pbar_id = NULL
)

Arguments

`inputpts`	TODO
`inlayer`	`SpatialPolygonsDataFrame` of fields (see also `id_fieldname`)
`filtered`	logical: is `inputpts` already filtered? If TRUE (default), no additional filter is applied; if FALSE, a standard automatic filter is applied.
`id_fieldname`	optional: name of the `inlayer` field containing unique ID of fields (default: `"idfield"`)
`interp_dir`	directory where rasters of single polygons are stores (default: temporary directory)
`out_path`	path of the output merged raster (default: temporary directory)
`interp_method`	interpolation method (`"krige"` or `"idw"`)
`smooth`	logical: should rasters be smoothed after interpolation?
`interp_res`	output raster resolution (numeric, in metres)
`out_crs`	optional: CRS of output raster (default: CRS of `inputpts`)
`grid_offset`	optional: grid offset from point (0,0) in `out_crs` (2-length numeric)
`samplesize`	maximum size of the sample of the original data to work with (default: 10000; if NA: all the points)
`samplescheme`	sampling scheme within geometries (`"random"`, `"strat_npts"` or `"strat_area"`)
`buffer_radius`	numeric: buffer (default: 15) to be applied internally to field borders.
`parallel`	(optional) Logical or integer: if TRUE (default), interpolation is executed using multiple cores in order to speed up the execution. The number of cores is automatically determined; specifying it is also possible (e.g. `parallel = 4`). If FALSE, the interpolation is forced to run with a single core.
`vgm`	named list of variograms (names must correspond to values of field `id_fieldname`). If NA (default), they are automatically computed.
`v_nmax`	TODO.
`v_maxdist`	TODO.
`merge`	logical: if TRUE (default), merge raster of single fields and return the path of the merged raster; if FALSE, return the paths of the single field rasters.
`overwrite`	Logical: should existing raster being reprocessed? (default: FALSE)
`.shiny_session`	TODO
`.shiny_pbar_id`	TODO
