Individual skill
portaljs-add-geo
Auto-ingest a geospatial file (GeoJSON, Shapefile, GeoPackage, KML/KMZ, FlatGeobuf, CSV-with-geometry) into a PortalJS portal on the user's own machine, with no server. Normalizes CRS to EPSG:4326, derives a PMTiles render tier and a GeoParquet query tier, pushes all three artifacts to Cloudflare R2 via Git LFS, and appends one dual-tier datasets.json entry the showcase auto-renders. Use when the source is a vector geo format that needs a map or spatial-query view.

# PortalJS — Add Geo
## Overview
Turn one geospatial upload into a **dual-tier** PortalJS dataset entirely on the user's
machine — **no server-side container compute**, keeping the zero-backend bet end-to-end.
From a single source the skill derives two serverless tiers plus the preserved original:
- **PMTiles** (render tier) — a vector-tile archive `<MapPreview>` renders with MapLibre GL
over HTTP range requests; any dataset size pans and zooms with no tile server.
- **GeoParquet** (query tier) — a GeoParquet 1.1 file (covering `bbox` column, Hilbert-sorted)
`<GeoQuery>` runs spatial SQL over in place via DuckDB-Wasm.
- **Original** — the untouched upload in its native CRS, kept downloadable.
