PowerShell Map

PowerShell.Map

Interactive 2D/3D map visualization for PowerShell using MapLibre GL JS and OpenStreetMap. Although usable standalone, this module is primarily designed for Claude Desktop integration via the PowerShell.MCP module, enabling AI-powered map visualization.

What's New in v1.0.1

Two major features have been added since v1.0.0:

• 🎮 3D Map Visualization - Interactive 3D terrain and building views with dynamic camera controls (Pitch, Bearing)
• 📝 Rich Marker Descriptions - Click markers to display detailed multi-line information, perfect for AI-powered context delivery

Additional improvements:

• Enhanced animation with configurable duration
• Stateful design - camera position and 3D mode preserved across commands
• Upgraded from Leaflet.js to MapLibre GL JS for better 3D performance

Features

• Interactive 2D/3D Map Display: View locations on OpenStreetMap with optional 3D terrain and buildings
• Rich Marker Information: Click markers to display detailed descriptions with multi-line text and emoji support
• Route Visualization: Display routes between two locations with turn-by-turn directions
• Animated Tours: Create animated tours that visit multiple locations sequentially
• Geocoding: Convert place names to coordinates using Nominatim
• Reverse Geocoding: Convert coordinates to place names
• Multiple Markers: Display multiple markers with custom colors, labels, and descriptions
• Stateful Camera: Pitch, bearing, and 3D mode preserved across commands
• CSV Pipeline Support: Import location data from CSV files

Claude Desktop Integration (AI-Powered)

PowerShell.Map integrates with Claude Desktop via PowerShell.MCP, enabling natural language map visualization.

Setup

1. Install PowerShell.MCP:

Install-Module PowerShell.MCP

1. Configure Claude Desktop to use PowerShell.MCP (see PowerShell.MCP documentation)

Usage

Once configured, simply ask Claude:

• "Show me a 3D tour of famous landmarks in Paris with detailed information"
• "Create a route from Big Ben to Buckingham Palace"
• "Display the Alps mountain range in 3D"
• "Show me the Normandy D-Day beaches with historical details for each"
• "Plan a tour of Italian Renaissance cities with descriptions"

Claude will automatically:

• Research location details
• Create rich descriptions with relevant information
• Generate maps with appropriate 3D settings
• Organize tours in logical sequences

Example: AI-Generated Historical Map

User: "Show me the major battles of World War I on the Western Front with details"

Claude creates:

• Chronological markers (1914-1918)
• Detailed battle information (dates, forces, casualties, outcomes)
• 3D terrain showing strategic geography
• Animated tour following the timeline
• Clickable descriptions for each battle

• PowerShell.MCP on PowerShell Gallery
• PowerShell.MCP on GitHub

Requirements

• PowerShell: 7.2 or later
• Platform: Windows 10/11
• Internet: Required for OpenStreetMap tiles and geocoding
• Browser: Modern browser with WebGL support (Chrome, Edge, Firefox)

Technical Details

• Map Engine: MapLibre GL JS (upgraded from Leaflet.js in v1.0.0)
• 3D Terrain: AWS Terrarium RGB elevation tiles
• 3D Buildings: OpenStreetMap building data with height tags
• Geocoding: Nominatim API (rate limit: 1 request/second)
• Server: Local HTTP server on http://localhost:8765/
• Projection: Web Mercator (EPSG:3857)

Performance Tips

• Large Datasets: Use -Duration 0 to disable animation for instant rendering
• 3D Mode: Disable 3D (-Disable3D) if performance is slow on older hardware
• Geocoding: Cache results to avoid repeated API calls
• Zoom Level: Use appropriate zoom (8-10 for regions, 15+ for landmarks)
• Multiple Markers: Consider grouping nearby locations to reduce clutter

Troubleshooting

Map doesn't open

• Check if port 8765 is available
• Try closing and reopening PowerShell
• Verify internet connection
• Check Windows Firewall settings

3D not working

• Ensure browser supports WebGL
• Check zoom level (3D buildings require zoom 14+)
• Try updating your browser
• Verify graphics drivers are up to date

Geocoding fails

• Verify internet connection
• Check Nominatim API status at https://nominatim.openstreetmap.org/
• Respect rate limit (1 request/second)
• Use coordinates directly if name lookup fails

Description not showing

• Click directly on the marker (not the label)
• Ensure Description parameter was provided
• Check browser console for errors
