pmtiles CLI ​

Installation ​

pmtiles is a single binary with no external dependencies.

The source code is on GitHub at protomaps/go-pmtiles.

To download, see Releases on GitHub for your OS and architecture.

An official Docker Hub image is available at protomaps/go-pmtiles.

CLI Overview ​

Local archives ​

The CLI works with local tilesets on disk, for example:

sh
pmtiles show test.pmtiles

Remote archives ​

However, pmtiles can also work with remote HTTP archives and tilesets on cloud storage, even in private buckets.

sh
pmtiles show https://r2-public.protomaps.com/protomaps-sample-datasets/cb_2018_us_zcta510_500k.pmtiles

pmtiles uses the go-cloud library for connecting and authenticating to cloud storage.

Commands for S3, Azure Blob and Google Cloud Storage:

INFO

Commands that uses URL characters like ? and &, should be escaped by a backslash \ in your shell.

sh
pmtiles show test.pmtiles --bucket=s3://BUCKET_NAME pmtiles show test.pmtiles --bucket=azblob://CONTAINER_NAME?storage_account=ACCOUNT pmtiles show test.pmtiles --bucket=gs://BUCKET_NAME

For S3-compatible blob storage (Minio, Cloudflare R2, etc) outside of AWS:

sh
pmtiles show test.pmtiles --bucket=s3://BUCKET_NAME?endpoint=https://example.com&region=auto

INFO

Some S3-compatible storage servers like Minio, Ceph and SeaweedFS may require additional URL options like s3ForcePathStyle=true.

Private buckets ​

pmtiles uses go-cloud's default authentication methods for each cloud provider.

For example, the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables are used to sign requests to private S3-compatible buckets:

sh
export AWS_ACCESS_KEY_ID=MY_KEY export AWS_SECRET_ACCESS_KEY=MY_SECRET pmtiles show NAME.pmtiles --bucket=s3://R2_BUCKET_NAME\?endpoint=https://R2_ACCOUNT_ID.r2.cloudflarestorage.com\&region=auto

Commands ​

show ​

bash
pmtiles show INPUT.pmtiles pmtiles show INPUT.pmtiles --bucket=s3://BUCKET_NAME pmtiles show INPUT.pmtiles --header-json pmtiles show INPUT.pmtiles --metadata

Print an archive's header data and metadata.

  • --header-json: print a JSON representation of part of the header to stdout.
  • --metadata: print the JSON metadata to stdout.

tile ​

bash
pmtiles tile INPUT.pmtiles 0 0 0

Output a single tile's contents to stdout.

verify ​

bash
pmtiles verify INPUT.pmtiles

Check that an archive is ordered correctly and has correct header information.

extract ​

bash
pmtiles extract INPUT.pmtiles OUTPUT.pmtiles --bbox=MIN_LON,MIN_LAT,MAX_LON,MAX_LAT pmtiles extract INPUT.pmtiles OUTPUT.pmtiles --region=REGION.geojson pmtiles extract https://example.com/INPUT.pmtiles OUTPUT.pmtiles --maxzoom=MAXZOOM pmtiles extract INPUT.pmtiles OUTPUT.pmtiles --maxzoom=MAXZOOM --bucket=s3://BUCKET_NAME

Create a smaller archive from a larger archive. The source archive may be local or remote. The source archive must be clustered.

Options:

  • --maxzoom: Extract only a subset of zoom levels. Extracting a full sub-pyramid from 0 to maxzoom is always an efficient operation that makes minimal I/O or network requests to the source archive.
  • --minzoom: Extract only a partial sub-pyramid. This may require many more requests than leaving the default --minzoom=0. Because this removes overview zoom levels, it should only be used in specific situations.
  • --region: a GeoJSON Polygon, Multipolygon, Feature, or FeatureCollection.
  • --download-threads Number of parallel requests to speed up downloads.
  • --overfetch extra data to download to batch small requests: 0.05 is 5%.

merge ​

bash
pmtiles merge INPUT_1.pmtiles INPUT_2.pmtiles OUTPUT.pmtiles pmtiles merge INPUT_1.pmtiles INPUT_2.pmtiles INPUT_3.pmtiles OUTPUT.pmtiles

Combine disjoint archives into a single archive. The output archive contains all tile data in the inputs. All inputs must be clustered and match in tile type and compression.

serve ​

The simplest way to consume PMTiles on the web is directly in the browser with pmtiles.js along with a renderer-specific client. However, decoding PMTiles on the server and exposing a ZXY API works with more clients and can result in lower latency. A ZXY API is directly supported by web and native renderers such as MapLibre, without needing the PMTiles client library. Using pmtiles serve also allows serving a public API from a private storage bucket.

INFO

When using pmtiles serve, requests for the raw file like /test.pmtiles, either whole or partial range requests, are not supported. A standard web server like Apache, Nginx or Caddy can serve those.

Serve a directory or bucket of tilesets (like TILESET.pmtiles) from local or cloud storage as a ZXY endpoint:

bash
pmtiles serve . # serves this directory at http://localhost:8080/TILESET/{z}/{x}/{y}.mvt  # the .pmtiles extension is added automatically # TileJSON at http://localhost:8080/TILESET.json pmtiles serve . --bucket=https://example.com pmtiles serve / --bucket=s3://BUCKET_NAME pmtiles serve PREFIX --bucket=s3://BUCKET_NAME

For ZXY URLs, the extension must match the type of the tiles in the archive, for example mvt, png, jpg, webp, avif.

Flags:

  • --cors=ORIGIN1,ORIGIN2 set the valid origins for the Access-Control-Allow-Origin CORS header. * is a valid value but must be escaped in your shell. Appropriate for development use.
  • --cache-size=SIZE_MB set the global size of the header and directory LRU cache, shared across all archives. Default is 64 MB.
  • --port=PORT specify the HTTP port. Defaults to 8080.
  • --public-url: Required for serving TileJSON. Specify the full URL as it should appear to the browser client like http://localhost:8080 or https://example.com.

For production usage, it's recommended to run behind a CDN or reverse proxy like Caddy to handle SSL and CORS. See the guide on Accelerating PMTiles.

convert ​

Convert an MBTiles archive to PMTiles.

bash
pmtiles convert INPUT.mbtiles OUTPUT.pmtiles

For the Docker image:

sh
docker run -v $(pwd):/data --rm protomaps/go-pmtiles convert /data/INPUT.mbtiles /data/OUTPUT.pmtiles

Options:

  • --no-deduplication: Do not attempt to de-duplicate tile contents. Use this to speed up convert if you know the input has only unique tiles.
  • --tmpdir: specify the location of the temporary directory.

cluster ​

Cluster an unclustered existing archive, optimizing the size and layout. Archives created by tippecanoe, planetiler, and the pmtiles CLI are already clustered.

bash
pmtiles cluster INPUT.pmtiles

Options:

  • --no-deduplication: Do not attempt to de-duplicate tile contents. Use this to speed up cluster if you know the input has only unique tiles.

upload ​

Upload an archive to cloud storage.

bash
# requires environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY credentials pmtiles upload INPUT.pmtiles REMOTE.pmtiles --bucket=s3://BUCKET_NAME # upload to a s3-compatible endpoint # some storage systems require path-style requests pmtiles upload INPUT.pmtiles REMOTE.pmtiles --bucket=s3://BUCKET_NAME?region=auto&endpoint=https://example.com&use_path_style=true

You will need write permissions to the bucket, for example this AWS IAM policy:

json
 {  "Version": "2012-10-17",  "Statement": [  {  "Effect": "Allow",  "Action": "s3:*",  "Resource": "arn:aws:s3:::my-bucket-name/*"  }  ]  }

edit ​

Change parts of the archive header, or replace the archive JSON metadata.

bash
pmtiles show NAME.pmtiles --header-json > header.json pmtiles show NAME.pmtiles --metadata > metadata.json  # make changes to header.json or metadata.json  pmtiles edit NAME.pmtiles --header-json=header.json --metadata=metadata.json
  • The tile_type, tile_compresssion, minzoom, maxzoom, bounds and center of the header can be edited. Other fields are not editable. Editing only the header will modify the file in-place.
  • Writing the JSON metadata requires writing a new copy of the archive, which will then replace NAME.pmtiles.

version ​

bash
pmtiles version

Print the version of the command line tool.
