@dlr-eoc/map-maplibre

how to use this in a ukis-angular (@dlr-eoc/core-ui) project

For examples see demo maps

add the following dependencies to the package.json

• "@dlr-eoc/map-maplibre"
• "@dlr-eoc/layer-control" (optional)
• "@dlr-eoc/base-layers-raster" (optional)

add styles from maplibre to your application

e.g. in your apps style file

// styles.scss/styles.css
@import 'maplibre-gl/dist/maplibre-gl.css';
...

or in the angular config file

// angular.json
...
  "styles": [
    ...
    "node_modules/maplibre-gl/dist/maplibre-gl.css",
    "src/styles.scss"
  ],
...

add the following to route-view.component.ts

import { MapMaplibreComponent } from '@dlr-eoc/map-maplibre';
import { LayerControlComponent } from '@dlr-eoc/layer-control';

...
 standalone: true,
 imports: [
    ...
    MapMaplibreComponent,
    LayerControlComponent
  ]

add the following to a route-view.component.html

<section class="content-area map-view">
    <ukis-map-maplibre [mapState]="mapStateSvc" [layersSvc]="layerSvc"></ukis-map-maplibre>
</section>

add the following to a route-view.component.ts

import { LayersService } from '@dlr-eoc/services-layers';
import { MapStateService } from '@dlr-eoc/services-map-state';
import { MapMaplibreService } from '@dlr-eoc/map-maplibre';

import { OsmTileLayer, EocLitemap, BlueMarbleTile } from '@dlr-eoc/base-layers-raster';

constructor(
    public layerSvc: LayersService,
    public mapStateSvc: MapStateService,
    public mapSvc: MapMaplibreService) { }

// add a OnInit Function
export class <MyComponent> implements OnInit...

ngOnInit() {
    this.addBaselayers();
}

addBaselayers() {
    const layers = [
        new OsmTileLayer({
        visible: false
        }),
        new EocLitemap({
        visible: true
        }),
        new BlueMarbleTile({
        visible: false
        })
    ];

    layers.map(l => this.layerSvc.addLayer(l, 'Baselayers'));
}

TODO

• There are currently no popups implemented for layers

• Some properties of Layers or Layergroups are currently not used. E.g.

• Layer.continuousWorld: this is not available in maplibre

• Layer.minResolution: this is not available in maplibre use minZoom

• Layer.maxResolution: this is not available in maplibre use maxZoom

• Layer.bbox: Works only with some sources see https://maplibre.org/maplibre-style-spec/sources/#sources - bounds

• Layer.events: TODO: https://maplibre.org/maplibre-gl-js/docs/API/classes/maplibregl.StyleLayer/ on/of

• Layer.crossOrigin: this is not available in maplibre
