🔎 PMTiles Viewer: https://pmtiles.io/ 🔎

PMTiles is a single-file archive format for tiled data. A PMTiles archive can be hosted on a commodity storage platform such as S3, and enables low-cost, zero-maintenance map applications that are "serverless" - free of a custom tile backend or third party provider.

• PMTiles Viewer - inspect and preview PMTiles local or remote PMTiles archives.

  • Archives on cloud storage may require CORS for the origin https://protomaps.github.io

• Vector Tiles Example (US Zip Codes)

Demos require MapLibre GL JS v1.15 or later.

Example of how to create a PMTiles archive from the Census Bureau Zip Code Tabulation Areas Shapefile using tippecanoe:

    # use GDAL/OGR to convert SHP to GeoJSON
    ogr2ogr -t_srs EPSG:4326 cb_2018_us_zcta510_500k.json cb_2018_us_zcta510_500k.shp
    # Creates a layer in the vector tiles named "zcta"
    tippecanoe -zg --projection=EPSG:4326 -o cb_2018_us_zcta510_500k_nolimit.pmtiles -l zcta cb_2018_us_zcta510_500k.json

Using the PMTiles command line tool:

pmtiles upload LOCAL.pmtiles "s3://BUCKET_NAME?endpoint=https://example.com&region=region" REMOTE.pmtiles

Using RClone (do rclone config first)

rclone copyto LOCAL.pmtiles r2:/BUCKET/REMOTE.pmtiles --progress --s3-chunk-size=256M --s3-upload-concurrency=2
