R Documentation

Get SPECTRE raster segments.

Description

Downloads SPECTRE segments according to a bounding box selection.

Usage

spectre.area(
  index,
  ext = c(-180, 180, -60, 90),
  normalize = FALSE,
  filepath = NULL
)

Arguments

`index`	numeric. A vector of integers specifying the layers. Refer to the list.
`ext`	numeric or SpatExtent. A vector of `xmin`, `xmax`, `ymin`, `ymax` or a `terra` spatial extent object (See `terra::ext()`). If no input is given, an extent of `xmin = -180, xmax = 180, ymin = -60, ymax = 90` is selected.
`normalize`	character or logical. Either logical on whether data should be normalized for the given interval or a character specifying a type of normalization. Type default to "standard". Check `gecko::normalize()` for more info.
`filepath`	character. An optional user defined path for the final output. If `NULL`, requested files are left in the current temp directory.

Value

SpatRaster.
