# Route Registration Export Tool

This tool manages RMI Project Export JSON files by merging new routes from GeoJSON data.

## Overview

The tool reads a GeoJSON file containing route geometries (LineStrings), parses the features, and either generates a new RMI project export JSON or updates an existing one. It automatically handles:
- Coordinate extraction from GeoJSON.
- Polyline encoding for the Google Roads API.
- Bounding box and center point calculation.
- Merging with existing export files.
- Writing output as zipped `.zip`.

## Files

- `main.py`: The main Python script that performs the conversion and merging.
- `config.yaml`: Configuration file for project metadata, file paths, and route settings.
- `sample_input.geojson`: A sample GeoJSON input file with redacted real-world geometries.
- `sample_project.json`: A sample RMI project export file (redacted version of the original Boston export).

## Prerequisites

- Python 3.x
- `PyYAML` library
- `pyproj` library

To install dependencies:
```bash
pip install PyYAML pyproj
```

## Usage

1. Configure file paths (and optional settings) in `config.yaml`.
2. (Optional) Set `base_export_file` to an existing export ZIP to merge new routes into it. The `project` section is taken from that file; use `project_info` only for fields you want to override.
3. Run the script:

```bash
python3 main.py config.yaml
```

The script will generate or update the JSON file as specified in the `output_export_file` path of your configuration.
