2. Service Layer
Publishing and distributing geo-services
Technologies:
- • GeoServer - Open source map server
- • MapServer - High-performance map server
- • MapProxy - Caching and tile serving
Functionality:
WMS, WFS, WMTS services, tile generation, styling (SLD/SE), feature filtering, transformations.
3. API Layer
Access to functionality via APIs
Technologies:
- • REST API - Modern HTTP-based API
- • GraphQL - Query language for APIs
- • WebSockets - Real-time bidirectional communication
Functionality:
CRUD operations, geocoding, routing, spatial analyses, authentication, rate limiting.
4. Application Layer
