Architecture Concept

The p2d2 platform is based on a modern web architecture with the following core components:

Frontend Architecture

• Astro Framework: Static site generation and component-based development
• TypeScript: Type-safe development for better code quality
• TailwindCSS: Utility-first CSS framework for consistent design
• OpenLayers: Map display and geodata visualization

Backend Services

• Astro Endpoints: Server-side functions for dynamic content
• Geodata Services: Integration of WMS/WMTS services
• Data Synchronization: Automated updating of municipality data

Data Management

• Content Collections: Structured management of municipality data
• Geodata Sources: Integration of external geoservices
• Local Storage: Browser-based data storage

System Components

Map Module

• OpenLayers-based map display
• Layer management for various geodata sources
• Interactive map functions (zoom, pan, feature selection)

Feature Editor

• Geometry editor for polygons and lines
• Integration with OpenStreetMap
• Data synchronization with backend

Municipality Management

• Content Collections for structured data
• Dynamic routing based on municipality data
• Responsive user interface

UI Components

• Reusable Astro components
• Consistent design system
• Mobile-optimized display

Data Flow

1. Initialization: Loading base configuration and municipality data
2. Map Rendering: Building the map with configured layers
3. User Interaction: Handling map interactions and editor functions
4. Data Persistence: Storing user inputs and configurations
