Ithlin – Geospatial Intelligence Platform
Full-stack GEOINT platform for military and intelligence operations planning and analysis
Ithlin combines interactive 2D/3D mapping with NATO-standard military symbology, knowledge graph relationships, temporal analysis, and comprehensive data management—all with offline-first capabilities. Designed for analysts and planners who need to visualize, track, and analyze geospatial intelligence data throughout the full intelligence cycle.

Geospatial Visualization
The mapping engine supports both tactical 2D analysis and strategic 3D globe visualization, with seamless switching between views while maintaining state and annotations.
2D MapLibre GL
- → High-performance vector tile rendering
- → Custom styling for tactical overlays
- → Smooth pan/zoom with clustering
3D Cesium Globe
- → Terrain elevation and imagery layers
- → 3D entity positioning with altitude
- → Camera flight animations
Coordinate Systems
MGRS, UTM, and decimal degrees with real-time conversion and copy-to-clipboard
Spatial Analysis
Distance/area measurement, buffer analysis, and geometry queries via Turf.js
Drawing Tools
Radial tool selector for creating points, lines, and polygons directly on the map
Military Symbology
Full implementation of MIL-STD-2525D and APP-6B military symbology standards, enabling standardized representation of military units, equipment, and activities.

Interactive Symbol Builder
Step-by-step UI for constructing symbols by selecting affiliation, dimension, function, and modifiers
Echelon-Based Rendering
Automatic symbol scaling based on unit echelon and current map zoom level
Text Modifiers
Unit designators, higher formation, speed, direction, and additional information fields
Symbol Taxonomy Browser
Browse and select from the complete APP-6B symbol hierarchy
Knowledge Graph & Intelligence Management
Neo4j-powered relationship tracking enables complex network analysis, connecting entities, places, and events through typed relationships with confidence scoring.

Entities
People, organizations, equipment, and facilities with custom attributes
Places
Geolocated points of interest with rich metadata and geometry
Events
Time-bound occurrences with priority and spatial references
Network Visualization
Interactive force-directed graph with color-coded nodes by entity type and sizing based on connection count
Confidence Scoring
Track intelligence confidence from low to confirmed with visual opacity indicators
Multi-Depth Traversal
Explore relationship networks at configurable depth levels for pattern discovery
Dynamic Forms
Configurable attribute definitions with drag-and-drop form builder for custom entity types
Temporal Analysis & Offline Capabilities
⏱️ Timeline Playback
Animate events over time with play/pause/step controls. Events appear on the map during playback with custom popups showing configurable fields.
- → Configurable date range selection
- → Visual progress bar with scrubbing
- → Map-integrated event visualization
📡 Offline-First Design
Core functionality works without network connectivity, designed for disconnected and air-gapped operational environments.
- → Local MBTiles tile server via Martin
- → Bundled JS libraries (no CDN dependencies)
- → Dockerized MongoDB and Neo4j
