canvod-utils 0.2.2

Configuration models and shared utilities for canVODpy

canvod-utils

Utility functions and configuration management for canvodpy.

Features

• Type-safe configuration: Pydantic models with validation
• YAML-based config: Human-readable configuration files
• CLI tools: Easy configuration management
• API-ready: Same models work for files and APIs

Installation

uv pip install -e packages/canvod-utils

Quick Start

1. Initialize Configuration

just config-init

This creates:

• config/processing.yaml - Processing parameters and credentials
• config/sites.yaml - Research site definitions
• config/sids.yaml - Signal ID selection

2. Edit Configuration

# Edit in your preferred editor
just config-edit processing
just config-edit sites
just config-edit sids

Or edit files directly:

• Set nasa_earthdata_acc_mail (optional) in config/processing.yaml for NASA CDDIS access
• Set gnss_site_data_root per site in config/sites.yaml
• Define your research sites in config/sites.yaml

3. Validate Configuration

just config-validate

4. Use in Code

from canvod.utils.config import load_config

# Load configuration
config = load_config()

# Access values
print(config.nasa_earthdata_acc_mail)
print(config.processing.aux_data.agency)

# FTP server selection (auto-detect based on nasa_earthdata_acc_mail)
servers = config.processing.aux_data.get_ftp_servers(config.nasa_earthdata_acc_mail)
for server_url, auth_email in servers:
    print(f"Server: {server_url}, Auth: {auth_email}")

Configuration Structure

processing.yaml

credentials:
  nasa_earthdata_acc_mail: [e-mail]  # Optional

aux_data:
  agency: COD
  product_type: final

processing:
  resource_mode: auto
  keep_rnx_vars: [SNR]
  aggregate_glonass_fdma: true

sites.yaml

sites:
  rosalia:
    gnss_site_data_root: /path/to/rosalia
    receivers:
      reference_01:
        type: reference
        directory: 01_reference/01_GNSS/01_raw
      canopy_01:
        type: canopy
        directory: 02_canopy/01_GNSS/01_raw
    vod_analyses:
      canopy_01_vs_reference_01:
        canopy_receiver: canopy_01
        reference_receiver: reference_01

sids.yaml

mode: all  # all, preset, custom
# preset: gps_galileo
# custom_sids: [G01|L1|C, G01|L2|W, ...]

CLI Commands

# Initialize configuration
just config-init

# Validate configuration
just config-validate

# Show current configuration
just config-show
uv run canvodpy config show --section processing  # filtered view

# Edit configuration
just config-edit processing
just config-edit sites
just config-edit sids

FTP Server Selection

• If nasa_earthdata_acc_mail is set: NASA CDDIS (primary) → ESA (fallback)
• If nasa_earthdata_acc_mail is null: ESA only (no authentication)
• ESA server is always available as fallback

Configuration Priority

1. Package defaults (lowest priority)
2. User configuration files (highest priority)

API-Ready Design

Same Pydantic models work for both local files and future API:

# Local development (YAML files)
config = load_config()

# Future API usage (same models!)
@app.post("/process")
def process(config: CanvodConfig):
    return processor.run(config)
