# SitelogParser

A Python library and command-line tool for parsing, validating, and exporting IGS (International GNSS Service) sitelog files. SitelogParser converts sitelog text files into structured Python dataclasses, enables programmatic manipulation of sitelog data, and exports them back to the IGS sitelog v2.0 format.

During the update process to version v1.2.0 AI tools for code improvements and documention generation was used. Tools like Github Copilot Pro and Gemini where used for that.

## Features

- **Parse IGS sitelog files** into type-safe Python dataclasses
- **Export sitelog data** back to IGS sitelog v2.0 format with automatic metadata updates
- **Generate Bernese files** (.sta) from sitelog data with equipment history and time ranges
- **Generate SINEX files** (.snx) in SINEX 2.02 format with coordinates and eccentricity data
- **Generate coordinate files** (.crd) with ECEF coordinates in multiple reference frames
- **Merge multiple sitelogs** into single station information, SINEX, or coordinate files
- **Command-line interface** for validation, listing, preparing, and generating files
- **Type hints** throughout for better IDE support and type checking
- **Automatic form metadata** computation (latest modification dates and changed sections)
- **Timestamp handling** with UTC timezone support
- **Glob pattern support** for batch file processing

## Installation

```bash
pip install sitelogparser
```

For development:
```bash
git clone <repository-url>
cd SitelogParser
pip install -e .
```

## Command-Line Usage

The `slp` command provides several operations:

### Validate a sitelog file

```bash
slp validate tests/AMST_20190705.txt
```

**Output:**
```
✓ Valid sitelog: tests/AMST_20190705.txt

📊 Statistics:
  Site: Amsterdam, Netherlands (AMST)
  DOMES: 13502M001
  Location: Amsterdam, Netherlands
  Receivers: 20
  Antennas: 6
  Last Modified: 2018-11-28
  Modified Sections: 3.19, 3.20
```

### List receivers, antennas, or metadata

```bash
# List all receivers
slp list tests/AMST_20190705.txt --type receivers

# List all antennas
slp list tests/AMST_20190705.txt --type antennas

# Show site metadata
slp list tests/AMST_20190705.txt --type metadata

# Show everything (default)
slp list tests/AMST_20190705.txt
```

## API Usage

### Basic Parsing

```python
from sitelogparser.common.sitelog import SiteLogParser

# Parse a sitelog file
parser = SiteLogParser(sitelog_file="path/to/sitelog.txt")
sitelog = parser.sitelog

# Access site information
print(f"Site: {sitelog.site_identification.site_name}")
print(f"Four-char ID: {sitelog.site_identification.four_character_id}")
print(f"DOMES: {sitelog.site_identification.iers_domes_number}")

# Access location data
location = sitelog.site_location
print(f"Location: {location.city}, {location.country}")
print(f"Coordinates: {location.latitude}, {location.longitude}")

# Iterate over receivers
for receiver in sitelog.gnss_receivers:
    print(f"Receiver {receiver.number}: {receiver.receiver_type}")
    print(f"  Serial: {receiver.serial_number}")
    print(f"  Firmware: {receiver.firmware_version}")

# Iterate over antennas
for antenna in sitelog.gnss_antennas:
    print(f"Antenna {antenna.number}: {antenna.antenna_type}")
    print(f"  Serial: {antenna.serial_number}")
    print(f"  Radome: {antenna.antenna_radome_type}")

# Access agency information
print(f"On-site agency: {sitelog.on_site_agency.name}")
print(f"Primary contact: {sitelog.on_site_agency.primary_contact.name}")
print(f"Email: {sitelog.on_site_agency.primary_contact.email}")
```

### Exporting Sitelog Data

```python
from sitelogparser.common.sitelog import SiteLogParser

# Parse existing sitelog
parser = SiteLogParser(sitelog_file="input.txt")

# Modify data programmatically
parser.sitelog.site_identification.site_name = "Updated Site Name"

# Export to new file (automatically updates form metadata)
output_text = parser.export_sitelog()
with open("output.txt", "w") as f:
    f.write(output_text)
```

### Creating a New Sitelog

```python
from sitelogparser.common.models import (
    Sitelog, FormInformation, SiteIdentification, SiteLocation,
    GNSSReceiver, GNSSAntenna, Agency, Contact
)
from sitelogparser.common.sitelog import SiteLogParser
from datetime import datetime, timezone

# Create sitelog structure
sitelog = Sitelog()

# Fill form information
sitelog.form_information = FormInformation(
    prepared_by="John Doe",
    report_type="NEW"
)

# Fill site identification
sitelog.site_identification = SiteIdentification(
    site_name="Example Site",
    four_character_id="EXMP",
    iers_domes_number="12345M001",
    date_installed=datetime(2025, 1, 1, tzinfo=timezone.utc).timestamp()
)

# Fill location
sitelog.site_location = SiteLocation(
    city="Example City",
    country="Example Country",
    latitude="+12.3456789012",
    longitude="+123.4567890123",
    elevation="100.0"
)

# Add receivers
receiver = GNSSReceiver(
    number=1,
    receiver_type="EXAMPLE RECEIVER",
    satellite_system="GPS",
    serial_number="12345",
    firmware_version="1.0.0",
    elevation_cutoff_setting="0",
    date_installed=datetime(2025, 1, 1, tzinfo=timezone.utc).timestamp(),
    date_removed=0.0,  # 0.0 means not removed yet
    temperature_stabilization="none"
)
sitelog.gnss_receivers.append(receiver)

# Add antennas
antenna = GNSSAntenna(
    number=1,
    antenna_type="EXAMPLE ANTENNA",
    serial_number="ANT123",
    antenna_reference_point="BPA",
    marker_arp_up_ecc="0.0000",
    marker_arp_north_ecc="0.0000",
    marker_arp_east_ecc="0.0000",
    alignment_of_true_n="0",
    antenna_radome_type="NONE",
    radome_serial_number="",
    antenna_cable_type="",
    antenna_cable_length="",
    date_installed=datetime(2025, 1, 1, tzinfo=timezone.utc).timestamp(),
    date_removed=0.0
)
sitelog.gnss_antennas.append(antenna)

# Add agency information
sitelog.on_site_agency = Agency(
    section="11",
    name="Example Organization",
    abbreviation="EXORG",
    mail_address="123 Example St, Example City, Country",
    primary_contact=Contact(
        name="Jane Doe",
        phone1="+1-555-0100",
        email="jane.doe@example.org"
    )
)

# Export to sitelog format
parser = SiteLogParser(sitelog_text="")
parser.sitelog = sitelog
output_text = parser.export_sitelog()

with open("new_sitelog.txt", "w") as f:
    f.write(output_text)
```

### Working with Timestamps

Dates in the dataclasses are stored as float timestamps (seconds since Unix epoch):

```python
from datetime import datetime, timezone

# Convert datetime to timestamp (for setting dates)
dt = datetime(2025, 1, 15, 12, 30, tzinfo=timezone.utc)
timestamp = dt.timestamp()
receiver.date_installed = timestamp

# Convert timestamp to datetime (for reading dates)
from sitelogparser.common.sitelog import SiteLogParser
parser = SiteLogParser(sitelog_file="sitelog.txt")
receiver = parser.sitelog.gnss_receivers[0]

if receiver.date_installed > 0:
    dt = datetime.fromtimestamp(receiver.date_installed, tz=timezone.utc)
    print(f"Installed: {dt.strftime('%Y-%m-%d %H:%M:%S %Z')}")

# Dates are exported in IGS format: CCYY-MM-DDThh:mmZ
# Empty dates (0.0) are shown as: (CCYY-MM-DDThh:mmZ)
```

### Data Models

The library uses Python dataclasses for type-safe data representation:

- **`Sitelog`**: Top-level container for all sitelog data
- **`FormInformation`**: Section 0 - Form metadata
- **`SiteIdentification`**: Section 1 - Site identification
- **`SiteLocation`**: Section 2 - Site location information
- **`GNSSReceiver`**: Section 3.x - Individual receiver configuration
- **`GNSSAntenna`**: Section 4.x - Individual antenna configuration
- **`Agency`**: Sections 11-12 - Agency information with contacts
- **`Contact`**: Contact person information

All dataclasses have full type hints and can be converted to dictionaries using the `to_dict()` method.
