Add Snowflake vector-tile demo (tileserver) as installable skill#282
Merged
Conversation
Three-arm vector-tile sample under samples/geospatial/tileserver: - dynamic ST_AsMVT via Martin on SPCS - precomputed PMTiles baked from the same data - native H3 aggregation for client-side deck.gl Packaged as a one-command, idempotent Cortex Code skill (.cortex/skills/deploy-tileserver) that detect-reuse-else-creates the Snowflake Postgres + PostGIS instance, SPCS infra, and the Martin service.
Syncs the latest deploy-tileserver skill into samples/geospatial/tileserver: - add build_source_snapshot.py (owned SOURCE_FEATURES snapshot, immune to a mid-run Marketplace share lapse) and teardown_tileserver.sh (dependency-ordered cleanup, optional Postgres drop) - preflight auto-installs Python deps and verifies the container daemon is live before any billable infra - rewritten README and a note that tippecanoe's progress meter is non-linear (plateaus at z11 then races through z12; not a hang) ....

- describe what the Martin tile server does (function sources for arm 1, mounted PMTiles for arm 2, catalog/TileJSON/Web UI) - add an open-source components table (Martin, PostGIS, tippecanoe, PMTiles, MapLibre GL, deck.gl) with roles and licenses - explain how the deploy-tileserver Cortex Code skill installs the stack, from Cortex Code or directly from a shell, and the layer order ....

- install_tileserver.sh now ends with a clear readiness banner: the public app URL, numbered next steps (sign-in, Web UI Inspect Tile Source for arms 1/2, raw tile endpoints, arm-3 H3 export + viewer), and a teardown/billing reminder. Handles the endpoint-not-yet-resolved case with the SHOW ENDPOINTS command. - SKILL.md: add an "After a successful install" section so the skill runner relays the same URL and steps to the user. ....

Summary
Adds a self-contained Snowflake vector-tile demo under
samples/geospatial/tileserver/, packaged as a one-command, idempotent Cortex Code skill (.cortex/skills/deploy-tileserver).The sample demonstrates three ways to serve the same dataset as vector tiles on Snowflake, so users can compare the tradeoffs:

Install
Idempotent, detect-reuse-else-create: provisions the Snowflake Postgres + PostGIS instance, SPCS infra (image repo, compute pool, stages, secret, EAIs), bakes PMTiles, and deploys the Martin service.
