Heritage GIS Architecture & Fundamentals
Scalable, reproducible spatial infrastructure: CRS rigor, governance, metadata, and orchestration patterns for archaeological research.
Archaeological & Heritage GIS Workflows Automation
Automated workflows for archaeologists, heritage managers, and Python GIS developers.
Archaeological projects accumulate complex spatial records across field campaigns, photogrammetric reconstructions, laboratory catalogues, and regulatory deliverables. This resource collects production-grade patterns for engineering those workflows into reproducible, audit-ready pipelines.
Written for archaeologists, heritage managers, Python GIS developers, and academic research teams. Every chapter targets a discrete operational step — from CRS hygiene and PostGIS schema design, to drone ingestion, mesh optimization, and FAIR-aligned metadata.
Three pillars
Architectures, pipelines, and databases for heritage spatial work
The site is organised around three pillars that mirror the lifecycle of a heritage GIS programme: foundations and governance, 3D documentation pipelines, and the spatial databases that hold the evidence.
Photogrammetry & 3D Site Mapping Pipelines
Drone ingestion, dense reconstruction, UV-aware texturing, and batch orchestration for production-grade 3D site mapping.
Artifact & Feature Spatial Database Design
PostGIS schemas, topological modelling, attribute synchronization and query optimization for multi-season excavation datasets.
