Align multiple raster sources onto a common analysis grid

Source: R/foundation_tiles.R
foundation_tile_align.Rd

Projects every input SpatRaster onto a single template (common CRS, common resolution, common extent), stacks them channel-wise, and returns the unified mosaic. Designed to be robust to mixed resolutions (SoilGrids at 250 m, WorldClim at 30 arc-sec, SRTM at 30 arc-sec, MODIS at 250 m, ERA5 at 0.1 degree) so MoCo v2 pretraining can consume a single multi-channel tensor.

Usage

foundation_tile_align(
  sources,
  target_res = 0.005,
  target_crs = "EPSG:4326",
  aoi = NULL,
  method = "bilinear"
)

Arguments

sources

Named list of terra::SpatRaster objects.

target_res

Numeric resolution of the output grid, in the units of target_crs.

target_crs

Character EPSG code of the output CRS (default "EPSG:4326").

aoi

Optional AoI to crop after reprojection (see foundation_tile_source_soilgrids()).

method

Resampling method for terra::project(). Defaults to "bilinear" (good for continuous covariates).

Value

A single terra::SpatRaster with one layer per input layer, aligned.
