# Polish Geospatial Layers Integration - Project Maps Complete! 🎉

## ✅ Successfully Integrated Into Main Project Maps

All Polish geospatial layers and Google layers have been successfully integrated into the main project's mapping system.

## 🗺️ Available Layers in Project Maps

### Base Layers (Mutually Exclusive)
1. **OpenStreetMap** - Default layer
2. **🇵🇱 Polish Orthophoto (Standard)** - High-quality aerial imagery
3. **🇵🇱 Polish Orthophoto (High Resolution)** - Ultra-high resolution aerial imagery
4. **🌍 Google Satellite** - Google satellite imagery
5. **🌍 Google Hybrid** - Google satellite with roads overlay
6. **🌍 Google Roads** - Google road map
7. **Satellite (Esri)** - Esri world imagery
8. **Topographic** - CartoDB Voyager topographic map

### Overlay Layers (Can be Combined with Transparency)
1. **📋 Polish Cadastral Data** - Property boundaries and parcel information (80% opacity)
2. **🏗️ Polish Spatial Planning** - Zoning and urban planning data (70% opacity)
3. **🛣️ LP-Portal Roads** - Detailed road network (90% opacity)
4. **🏷️ LP-Portal Street Names** - Street names and descriptions (100% opacity)
5. **📐 LP-Portal Parcels** - Municipal property parcels (60% opacity)
6. **📍 LP-Portal Survey Markers** - Survey markers and reference points (80% opacity)

## 📁 Updated Files

### Core Map Components
- **`src/components/ui/LeafletMap.js`** - Main project map component ✅
- **`src/components/ui/EnhancedLeafletMap.js`** - Enhanced map component ✅
- **`src/components/ui/mapLayers.js`** - Layer configuration ✅

### Map Usage in Project
- **`src/app/projects/map/page.js`** - Projects map page (uses LeafletMap)
- **`src/components/ui/ProjectMap.js`** - Individual project maps (uses LeafletMap)

## 🚀 How It Works

### Layer Control
- **Layer Control Button** (📚) appears in top-right corner of maps
- **Base Layers** - Radio buttons (only one can be selected)
- **Overlay Layers** - Checkboxes (multiple can be selected)

### Transparency Handling
- **Base layers** are fully opaque (no transparency)
- **Overlay layers** have appropriate transparency levels:
  - Cadastral data: Semi-transparent for property boundaries
  - Planning data: Semi-transparent for zoning information
  - Roads: Mostly opaque for visibility
  - Street names: Fully opaque for text readability
  - Parcels: Semi-transparent for boundary visualization
  - Survey markers: Semi-transparent for reference points

### Automatic Integration
All existing project maps now have access to:
- Polish orthophoto layers
- Google satellite/road layers
- Polish government WMS overlays
- LP-Portal municipal data overlays

## 🎯 Benefits

1. **Enhanced Mapping Capabilities**: Rich selection of base layers for different use cases
2. **Polish-Specific Data**: Access to official Polish cadastral and planning data
3. **Transparency Support**: Overlays work correctly with transparency
4. **Maintained Performance**: Layers load efficiently and switch smoothly
5. **User-Friendly**: Clear naming with emojis for easy identification

## 🌍 Geographic Coverage

- **Polish Orthophoto**: Complete coverage of Poland
- **Polish Cadastral**: Official property boundaries across Poland  
- **Polish Planning**: Zoning data where available
- **LP-Portal**: Municipal data (specific regions)
- **Google Layers**: Global coverage
- **Esri Satellite**: Global coverage

## 📱 Test Locations

Perfect locations to test all layers:
- **Kraków**: [50.0647, 19.9450] - Historic center with detailed cadastral data
- **Warszawa**: [52.2297, 21.0122] - Capital city with planning data
- **Gdańsk**: [54.3520, 18.6466] - Port city with orthophoto coverage
- **Wrocław**: [51.1079, 17.0385] - University city
- **Poznań**: [52.4064, 16.9252] - Industrial center

## 🔧 Technical Implementation

### WMTS Integration
- Polish orthophoto uses proper WMTS KVP format
- EPSG:3857 coordinate system for Leaflet compatibility
- Standard 256x256 tile size for optimal performance

### WMS Overlay Integration  
- Transparent PNG format for overlays
- Proper parameter configuration for each service
- Optimized opacity levels for each overlay type
- Tiled requests for better performance

### React/Leaflet Architecture
- Uses `react-leaflet` components: `TileLayer` and `WMSTileLayer`
- Proper layer control with `BaseLayer` and `Overlay` components
- Icon fixes for marker display
- SSR-safe dynamic imports

## 🎉 Status: COMPLETE

✅ All Polish geospatial layers integrated
✅ Google layers integrated  
✅ Transparency properly handled
✅ Layer control working
