Features
--------

[](#features)

- Fetches speed limits from the Norwegian NVDB API for given coordinates
- Supports searching with an expanding radius if no speed limit is found initially
- Batch lookup for multiple coordinates
- Configurable API endpoint, search radius, and coordinate bounds
- Designed for Laravel, but can be used in any PHP project

---

Installation
------------

[](#installation)

Install the package via Composer:

```
composer require devshaded/nvdb-speed-limits
```

Publish the config file (optional):

```
php artisan vendor:publish --tag="nvdb-speed-limits-config"
```

---

Configuration
-------------

[](#configuration)

The configuration file allows you to customize API settings, search parameters, and coordinate bounds. Example:

```
return [
    'api' => [
        'base_url' => 'https://nvdbapiles-v3.atlas.vegvesen.no',
        'timeout' => 30,
        'headers' => [
            'accept' => 'application/vnd.vegvesen.nvdb-v3-rev1+json',
            'X-Client' => 'LaravelNvdbSpeedLimits/1.0',
        ],
    ],
    'search' => [
        'default_radius' => 0.0001, // ~11 meters
        'max_radius' => 0.005,      // ~550 meters
        'radius_multiplier' => 3,   // For expanding search
    ],
    'bounds' => [
        'latitude' => [57, 72],
        'longitude' => [4, 32],
    ],
];
```

---

Usage
-----

[](#usage)

Import the facade or use the class directly:

```
use DevShaded\NvdbSpeedLimits\Facades\NvdbSpeedLimits;
// or
use DevShaded\NvdbSpeedLimits\NvdbSpeedLimits;
```

### Get Speed Limit for a Coordinate

[](#get-speed-limit-for-a-coordinate)

```
$result = NvdbSpeedLimits::getSpeedLimit(59.9139, 10.7522);

if ($result->found) {
    echo "Speed limit: " . $result->recommended['speed'] . " km/h";
} else {
    echo "No speed limit found.";
}
```

#### Optional: Specify a Search Radius

[](#optional-specify-a-search-radius)

```
$result = NvdbSpeedLimits::getSpeedLimit(59.9139, 10.7522, 100); // 100 meters
```

### Get Speed Limit with Expanded Search

[](#get-speed-limit-with-expanded-search)

This method will automatically expand the search radius until a speed limit is found or the maximum radius is reached.

```
$result = NvdbSpeedLimits::getSpeedLimitWithExpandedSearch(59.9139, 10.7522);

if ($result->found) {
    echo "Speed limit: " . $result->recommended['speed'] . " km/h";
}
```

### Get Speed Limits for Multiple Coordinates

[](#get-speed-limits-for-multiple-coordinates)

You can pass an array of coordinates (with `lat`/`lng` or `latitude`/`longitude` keys):

```
$coordinates = [
    ['lat' => 59.9139, 'lng' => 10.7522],
    ['latitude' => 60.3913, 'longitude' => 5.3221],
    ['lat' => 61.1234, 'lng' => 11.5678],
];

$results = NvdbSpeedLimits::getSpeedLimitsForCoordinates($coordinates);

foreach ($results as $item) {
    if ($item['error']) {
        echo "Error for coordinate (" . json_encode($item['coordinate']) . "): " . $item['error'] . "\n";
    } else {
        echo "Speed limit at (" . $item['coordinate']['lat'] . ", " . $item['coordinate']['lng'] . "): " . $item['result']->recommended['speed'] . " km/h\n";
    }
}
```

---

Error Handling
--------------

[](#error-handling)

- If invalid coordinates are provided, an `InvalidCoordinatesException` will be thrown.
- For batch lookups, errors are included in the result array for each coordinate.
- Always check the `found` property on the result object to determine if a speed limit was found.

---

Testing
-------

[](#testing)

Run the tests with:

```
composer test
```
