Write a 4D time-cube raster to .vec — vec_write_time

Each (band, time) combination becomes a stack of tiles tagged with the chosen time stamp. Stamps are stored as int64 in the per-tile index entry; a value of 0 is reserved for "untimed" so this writer remaps any caller-supplied 0 to 1 internally.

Usage

vec_write_time_cube(
  x,
  times,
  path,
  dtype = "f32",
  tile_size = 512L,
  layout = c("image", "pixel"),
  extent = NULL,
  gt = NULL,
  epsg = 0L,
  nodata = NA_real_,
  band_names = NULL,
  compression = c("fast", "balanced", "max")
)

Arguments

x: Numeric 4D array c(rows, cols, bands, time).
times: Numeric/integer vector with length(times) == dim(x)[4], in the unit of your choice (epoch ms, year, step index).
path: Output .vec path.
dtype: Storage dtype (see vec_write_raster).
tile_size: Tile edge in pixels.
layout: Tile layout — one of "image" (default; one tile per (band, time, ty, tx), optimal for "give me one full image at time T" reads) or "pixel" (Phase 6b; one tile per (band, ty, tx) holding the full time stack as [tw*th, n_time], optimal for "give me the time series at pixel (x, y)" reads).
extent, gt, epsg, nodata, band_names, compression: Same semantics as vec_write_raster().

Value

Invisible NULL.
