Build Production-Grade Geospatial APIs
Design scalable spatial REST APIs, optimise PostGIS queries, implement intelligent caching layers, and deploy geospatial services that handle millions of concurrent requests with sub-50 ms response times.
Practical guides covering the complete stack from coordinate validation and bounding-box indexing through to vector tile generation and CDN distribution — written for backend engineers, GIS platform architects, and SaaS founders.
Everything you need to launch a spatial API
Core Geospatial API Architecture
Layered spatial design, PostGIS as a computational engine, async FastAPI patterns, OGC-compliant serialisation, cursor-based pagination, and API versioning for GIS endpoints.
Explore architecture →Advanced Spatial Endpoints & Data Contracts
Strict Pydantic v2 geometry validation, GiST index-aware query patterns, KNN routing, async bulk ingestion with Celery, and idempotent spatial writes at scale.
Explore endpoints →High-Performance Caching & Query Optimization
Redis spatial cache key normalisation, EXPLAIN ANALYZE for PostGIS, PgBouncer transaction pooling, vector tile generation with ST_AsMVT, and CDN edge distribution strategies.
