# LatLong provides a lightweight library for common latitude and longitude calculation. #

This library supports both, the "Haversine" and the "Vincenty" algorithm.

"Haversine" is a bit faster but "Vincenty" is far more accurate!

Catmull-Rom algorithm is used for smoothing out the path.

## Basic usage #

### Distance #

``````    final Distance distance = new Distance();

// km = 423
final int km = distance.as(LengthUnit.Kilometer,
new LatLng(52.518611,13.408056),new LatLng(51.519475,7.46694444));

// meter = 422591.551
final int meter = distance(
new LatLng(52.518611,13.408056),
new LatLng(51.519475,7.46694444)
);

``````

## Offset #

``````    final Distance distance = const Distance();
final num distanceInMeter = (EARTH_RADIUS * math.PI / 4).round();

final p1 = new LatLng(0.0, 0.0);
final p2 = distance.offset(p1, distanceInMeter, 180);

// LatLng(latitude:-45.219848, longitude:0.0)
print(p2.round());

// 45° 13' 11.45" S, 0° 0' 0.00" O
print(p2.toSexagesimal());

``````

## Path smoothing #

``````    // zigzag is a list of coordinates
final Path path = new Path.from(zigzag);

// Result is below
final Path steps = path.equalize(8,smoothPath: true);
``````

## Features and bugs #

Please file feature requests and bugs at the issue tracker.

 Popularity: Describes how popular the package is relative to other packages. [more] 95 Health: Code health derived from static analysis. [more] -- Maintenance: Reflects how tidy and up-to-date the package is. [more] -- Overall: Weighted score of the above. [more] 48

The package version is not analyzed, because it does not support Dart 2. Until this is resolved, the package will receive a health and maintenance score of 0.

#### Analysis issues and suggestions

Support Dart 2 in `pubspec.yaml`.

The SDK constraint in `pubspec.yaml` doesn't allow the Dart 2.0.0 release. For information about upgrading it to be Dart 2 compatible, please see https://dart.dev/dart-2#migration.

#### Maintenance issues and suggestions

Make sure `dartdoc` successfully runs on your package's source files. (-10 points)
