OxiGDAL Services

OGC-compliant web service implementations for geospatial data access and processing.

Features

WFS (Web Feature Service) 2.0/3.0: Vector data access with filtering and transactions
WCS (Web Coverage Service) 2.0: Raster data access with subsetting and format conversion
WPS (Web Processing Service) 2.0: Geospatial processing with built-in algorithms
CSW (Catalog Service for the Web) 2.0.2: Metadata catalog search and retrieval

Standards Compliance

This crate follows official OGC standards:

OGC WFS 2.0.0 (ISO 19142:2010)
OGC WFS 3.0 (OGC API - Features Part 1: Core)
OGC WCS 2.0.1 Core
OGC WPS 2.0.0
OGC CSW 2.0.2 (ISO 19115/19119)

Quick Start

use oxigdal_services::{wfs, wcs, wps, csw};
use axum::{Router, routing::get};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create WFS service
    let wfs_info = wfs::ServiceInfo {
        title: "My WFS Service".to_string(),
        abstract_text: Some("Vector data service".to_string()),
        provider: "COOLJAPAN OU".to_string(),
        service_url: "http://localhost:8080/wfs".to_string(),
        versions: vec!["2.0.0".to_string()],
    };
    let wfs_state = wfs::WfsState::new(wfs_info);

    // Build router
    let app = Router::new()
        .route("/wfs", get(wfs::handle_wfs_request).with_state(wfs_state));

    // Serve
    let listener = tokio::net::TcpListener::bind("0.0.0.0:8080").await?;
    axum::serve(listener, app).await?;

    Ok(())
}

Supported Operations

Architecture

The crate is organized into four main modules:

wfs/: Web Feature Service implementation
wcs/: Web Coverage Service implementation
wps/: Web Processing Service implementation
csw/: Catalog Service for the Web implementation

Each module provides:

Service state management
Request parameter parsing
OGC-compliant XML/JSON response generation
Error handling with proper exception reports

COOLJAPAN Policies

Pure Rust: No C/C++ dependencies
No unwrap(): All error paths handled properly
Workspace: Uses workspace dependencies
Files < 2000 lines: Modular organization (largest file: 504 LOC)

Performance

Async request handling with Tokio
Efficient XML generation with quick-xml
DashMap for concurrent service registries
LRU caching support
