A cluster computing framework for processing large-scale geospatial data
A single-node analytical database engine with geospatial as a first-class citizen
A benchmark for assessing geospatial SQL analytics query performance across database systems
MCP server for spatial analysis over remote GeoParquet files, read in place by DuckDB — no import step, predicate and projection pushdown into the remote Parquet.
Esercitazione guidata sui database geospaziali
AtlasSQL-BR: A Brazilian Portuguese Geospatial Text-to-SQL Dataset with Spatial Hierarchies
Production-grade engineering reference for automated parcel & property boundary data pipelines — PostGIS/Shapely/GeoPandas ETL, cadastral data architecture & standards, and topology repair.
A reproducible geospatial analytics platform for exploring neighbour change across Toronto.
PostGIS analysis of global land surface exposure by geologic period
High-Performance DuckDB Spatial Studio & Cloud GeoParquet Engine for QGIS
Production patterns for spatial data on Apache Iceberg and Delta Lake — partitioning, predicate pushdown, query engines (DuckDB/Trino/Sedona), GeoParquet, and Python workflows. An engineering reference site.
pgRouting patterns for PostGIS network analysis: shortest path, driving distance, isochrones, turn restrictions, and traffic-aware routing.
Reproducible PostGIS spatial-SQL pipeline for geospatial site screening: Docker, pinned open data, tests, CI.
Full-stack GIS routing MVP using PostGIS, pgRouting, Flask, Docker, and Leaflet for route alternatives, blocked zones, and traffic-point simulation.
Production-focused guides and runnable Python, SQL & CLI recipes for automating SpatiaLite & GeoPackage — offline-first spatial databases: format internals, serialization, R-tree indexing, transactions, and field sync.
Interactive scrollytelling map of Austin urban heat: summer land surface temperature vs tree canopy, impervious surface, and income across 65 neighborhoods. Earth Engine, PostGIS, R, Leaflet.
Dockerized PostGIS demo screening candidate solar/wind sites against grid proximity and protected land, tagged with real South African municipal boundaries (MDB shapefile).
Production PostGIS patterns & best practices for PostgreSQL spatial databases: GiST/SP-GiST/BRIN spatial indexing, spatial joins & nearest-neighbor queries, SRID & coordinate systems, vector tiles (ST_AsMVT), geometry data quality, partitioning. Runnable SQL examples with Docker.
Curated, example-driven reference for 92 PostGIS ST_* functions and spatial operators. Every entry has a SQL example with its real result, psycopg and GeoAlchemy2 snippets, SRID gotchas, GiST index behaviour and common mistakes. Search from the terminal, or generate a single self-contained searchable HTML page.
Production-grade spatial data pipelines with dbt, PostGIS, and DuckDB — practical guides on CRS governance, geometry validation, spatial macros, and CI testing.
