Discover tiles and coverage

In CRAN or offline builds, network-dependent chunks are not evaluated.

This example uses BlueTopo tiles covering New York Harbor. The workflow demonstrates tile discovery, checksum-verified asset retrieval, and file-backed raster access with terra.

Coverage is geometric tile-index coverage rather than a data-quality measure.

Example area

Selected tiles

tiles <- bluertopo_tiles(
  real_aoi,
  resolution = "native",
  coverage = "warn",
  quiet = TRUE
)

Coverage diagnostics

The selected tile table includes shortened GeoTIFF and RAT URLs from the current catalog records.
