# Copernicus

A flutter_maps extension package for utilising the Copernicus API to retrieve sentinel satellite imagery.

## Features

This package provides a `CopernicusLayer` widget that can be used in conjunction with the `flutter_map` package to display Copernicus satellite imagery on a map.

## Getting started

To use this package, add `copernicus` as a [dependency in your pubspec.yaml file](https://flutter.dev/docs/development/packages-and-plugins/using-packages).

```yaml

dependencies:

  copernicus: ^1.0.1

```

## Example

Here is an example of how to use this package:

```dart

import 'package:copernicus/copernicus.dart';

import 'package:flutter/material.dart';

import 'package:flutter_map/flutter_map.dart';

import 'package:latlong2/latlong.dart';

import 'package:flutter_map_cancellable_tile_provider/flutter_map_cancellable_tile_provider.dart';

void main() {

  runApp(const CopernicusExampleApp());

}

class CopernicusExampleApp extends StatelessWidget {

  const CopernicusExampleApp({super.key});

  @override

  Widget build(BuildContext context) {

    return const MaterialApp(

      title: 'Copernicus Example',

      home: HomePage(),

    );

  }

}

class HomePage extends StatefulWidget {

  const HomePage({super.key});

  @override

  State createState() => _HomePageState();

}

class _HomePageState extends State {

  String clientId = 'YOUR_CLIENT_ID';

  String clientSecret = 'YOUR_CLIENT_SECRET';

  @override

  Widget build(BuildContext context) {

    final mapOptions = MapOptions(

      initialCenter: const LatLng(-27.47, 153.02),

      initialZoom: 10,

      cameraConstraint: CameraConstraint.contain(

        bounds: LatLngBounds(

          const LatLng(-90, -180),

          const LatLng(90, 180),

        ),

      )

    );

    return FlutterMap(

      options: mapOptions,

      children: [

        TileLayer(

          urlTemplate: 'https://tile.openstreetmap.org/{z}/{x}/{y}.png',

          subdomains: const ['a', 'b', 'c'],

          userAgentPackageName: 'com.example.copernicus',

          tileProvider: CancellableNetworkTileProvider(),

        ),

        CopernicusLayer(

          clientId: clientId, 

          clientSecret: clientSecret, 

          data: const [

            CopernicusRequestData(

              satillite: CopernicusSatillite.s2l2a, 

              filteringOptions: CopernicusFilteringOptions(

                mosaickingOrder: CopernicusMosaickingOrder.mostRecent,

                maxCloudCoverage: 100,

              ),

              processingOptions: CopernicusProcessingOptions(

                downSampling: CopernicusSampling.nearest,

                upSampling: CopernicusSampling.bicubic,

              )

            )

          ]

        )

      ],

    );

  }

}

```
