Some functions like [get_tiles] return multiple separate files when it can be useful to have a single larger raster instead. This function is a thin wrapper over [sf::gdal_utils(util = "warp")], making it easy to collapse those multiple raster files into a single TIFF.

merge_rasters(
  input_rasters,
  output_raster = tempfile(fileext = ".tif"),
  options = character(0),
  force_fallback = FALSE
)

Arguments

input_rasters

A character vector containing the file paths to the georeferenced rasters you want to use.

output_raster

The file path to save the merged georeferenced raster to.

options

Optionally, a character vector of options to be passed directly to [sf::gdal_utils].

force_fallback

Logical: if TRUE, uses the much slower fallback method by default. This is used for testing purposes and is not recommended for use by end users.

Value

`output_raster`, invisibly.

Examples

if (FALSE) { simulated_data <- data.frame( lat = c(44.10379, 44.17573), lng = c(-74.01177, -73.91171) ) simulated_data <- sf::st_as_sf(simulated_data, coords = c("lng", "lat")) img_files <- get_tiles(simulated_data) merge_rasters(img_files[[1]]) }
