Git Backed Catalog
Create, maintain, or contribute to a Portolan catalog whose metadata lives in a git repository, with CI validating every change. Use when someone wants to publish a catalog they can roll back and take pull requests on, or wants to fix metadata in someone else's catalog.
Reading Portolan
Use when exploring, querying, analyzing, or visualizing data from a Portolan catalog (STAC-based cloud-native geospatial data). Covers navigating STAC metadata, querying GeoParquet with DuckDB, cross-dataset joins, geospatial analysis, and creating interactive maps with PMTiles/MapLibre/deck.gl/Potree.
Portolan Migrate
Bring an existing non-compliant catalog or published dataset into Portolan compliance without rebuilding it — audit what is there, decide whether to patch or re-extract, repair metadata, styles and data, prove conformance, then republish and prune what went stale. Use when a catalog already exists and falls short of the spec, when a dataset was published before Portolan, or when someone says a ca…
Portolan Bootstrap
Build a complete, well-documented Portolan catalog from a data source — research the data and its publisher, convert to cloud-native formats, write documentation and styles that make it usable, and publish. Use when someone wants to publish, mirror, or 'portolan-ify' a dataset, an open data portal, an ArcGIS or WFS service, or a folder of geospatial files.
Portolan Thumbnails
Generate framed, checked thumbnails from Portolan collections using chiitiler (MapLibre GL Native). Renders the collection's actual styles/default.json server-side with an optional basemap, frames every bbox to the browser card's 3:2 shape, and gates each image on an automated blank probe plus a visual review. Requires Node.js 18+.
Portolan Cli
Use when publishing, managing, or converting cloud-native geospatial data catalogs with the Portolan CLI. Covers init, add, check, push, pull, sync, partitioning, and format conversion workflows.
Sourcecoop
Upload geospatial data to Source Cooperative with proper metadata and READMEs using Portolan CLI.
Portolan Consume
Guide users through querying and exploring Portolan/STAC catalogs with optimized GeoParquet and COGs
Register Catalog
Register a Portolan catalog in the Portolan registry by opening a pull request that adds a catalog entry file.
Report Catalog Issue
Report a problem with a catalog registered in the Portolan registry by opening a catalog feedback issue against it.
