Compliance-first geospatial engineering

Standardize, normalize, and validate spatial data — deterministically.

Geospatial Schema is a reference resource for GIS data managers, government technology teams, and Python ETL engineers building production pipelines against INSPIRE, FGDC, OGC, ISO 19115, and local government schemas. Each guide pairs declarative configuration patterns with executable examples so transformations stay idempotent and auditable.

Explore attribute mapping rules, CRS normalization workflows, validation gates, batch sync strategies, CI gating, and compliance reporting — organized into three architectural pillars below.

Schema Architecture & Standards INSPIRE, FGDC, ISO 19115 alignment, schema registries, declarative mapping, and cross-platform schema translation. CRS Normalization & Sync Projection workflows, datum transformation fallback chains, tolerance thresholds, and multi-CRS harmonization. Attribute Transformation & ETL Batch schema processing, field renaming and type coercion, nested GeoJSON flattening, and resilient error handling.

What you’ll find here

Every guide is engineered for production use: declarative schema configurations, strict tolerance thresholds, deterministic CRS handling, and auditable CI gating. Browse by topic or follow the cross-links between guides to assemble an end-to-end pipeline.
