System Documentation & Integration Guide

EIGIS v2.0 — Microservices Architecture

📐 Database Schema

PostGIS 3.4 with 14 normalized tables supporting 3 interconnected themes:

Core: projects, personnel, field_trips, observations, photos, audit_log
Surface Geological: soil_profiles, soil_horizons, rock_descriptions, lithological_units
Structural: discontinuity_measurements, slope_stability, rock_mass_classifications, landslide_inventory
Geothermal: geothermal_manifestations, geothermal_gradients
Sampling: samples (unified), geochemistry_results
Future: geophysical_surveys, drilling_data, petrography

⚡ Spatial Indexing Strategy

GiST indexes on all geometry columns for O(log n) spatial queries
Composite GiST indexes on (geom, observation_type) for filtered rendering
Geography-cast indexes for ST_DWithin radius queries
Materialized views (mv_dashboard_metrics, mv_map_clusters) for dashboard latency <50ms
ST_ClusterDBSCAN for adaptive zoom-level clustering
