ZQM Computing — Geospatial Arm of ZQM Labs

ZQM Computing is the geospatial engineering arm of ZQM Labs — the games studio behind Z's Quests & Mischief. We build the geospatial patterns, data infrastructure, and tooling that ground ZQM Labs games in real-world locations across Volusia County, Florida.

Who this is for

Geospatial developers, GIS analysts, data engineers, and Python developers who need production-tested patterns for spatial data workflows. Also game developers building location-based experiences.

The games connection

ZQM Labs builds location-based scavenger-hunt games (Z's Quests & Mischief). ZQM Computing provides the geospatial engine:

Layer Tool Use in games
Desktop QGIS Game design, location scouting
Conversion GDAL Asset processing, reprojection
Python GeoPandas Spatial analysis, location selection
Database PostGIS System of record for game data
Routing pgRouting Route optimization, game paths
Analytics DuckDB Fast telemetry analysis
Raster COG/STAC Cloud-native map serving
Frontend MapLibre Game UI rendering
Grid H3 Location binning, leaderboards

Geospatial repos (14 public)

Layer Repo Description
System of Record postgis-patterns Production PostGIS patterns: spatial indexing, MVT, KNN
System of Record pgrouting-patterns Routing, shortest path, isochrones, network analysis
System of Record geospatial-api-reference OGC API - Features with FastAPI + PostGIS
Conversion gdal-patterns GDAL/OGR CLI: reprojection, conversion, VRT
Python geopandas-patterns GeoPandas: spatial joins, CRS, overlays
Columnar geoparquet-patterns GeoParquet: partitioning, predicate pushdown
Raster cog-patterns Cloud Optimized GeoTIFF: creation, serving
Discovery stac-patterns STAC: catalogs, validation, search API
Frontend maplibre-patterns MapLibre GL JS: vector tiles, 3D terrain
Grid h3-patterns H3: hexagonal binning, aggregation
Desktop qgis-resources QGIS expressions, PyQGIS, styles
Analytics duckdb-spatial-patterns DuckDB: SQL spatial, GeoParquet, H3
Infrastructure proxmox-ceph-operations Proxmox VE + Ceph runbooks
AI ops ollama-fleet-patterns Ollama fleet operations
Umbrella geospatial-patterns Index of all geospatial repos

Games monorepo

  • zqm-labs (private) — Z's Quests & Mischief: player PWA, PocketBase backend, Twine content, Hugo site, Docker infra

Quick start

# Python stack
pip install geopandas duckdb pystac rasterio h3

# System stack
sudo apt install gdal-bin postgresql postgis pgrouting

# Docker stack
docker-compose up -d  # pgrouting-patterns

What we do

  • Geospatial patterns — production-tested open-source repos for every layer of the geospatial stack
  • Data infrastructure — Project Volusia data portal, DuckDB analytics, PostGIS system of record
  • Tooling — conversion (GDAL), Python (GeoPandas), routing (pgRouting), rasters (COG/STAC), frontend (MapLibre), grids (H3)
  • AI ops — Ollama fleet management patterns
