# Download original assets

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`. Raster Attribute Table (RAT) sidecars are retained with the source GeoTIFF assets.

## Example area

## First download

    manifest <- bluertopo_download(
      real_aoi,
      path = real$download_dir,
      resolution = "native",
      coverage = "fill",
      rat = TRUE,
      verify = "sha256",
      on_exists = "verify",
      progress = FALSE,
      quiet = TRUE
    )

## Reuse existing verified files

## Manifest files

## Source domain summary

## Download status counts

The second call reports `reused_verified` for files that already exist and still match NOAA SHA-256 checksums. RAT sidecars are downloaded and verified with the GeoTIFF assets.
