@dlr-eoc/map-tools

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

This repository contains 3 ui components:

1. mouse-position: shows projected coordinates of mouse pointer
   <ukis-mouse-position></ukis-mouse-position>
2. navigator: allows to insert coordinates in order to navigate the map to desired position
   <ukis-projection-switch [mapSvc]="mapSvc" [projectionList]="projections"></ukis-projection-switch>
3. projection-switch: ui element for interactive projection switch
   <ukis-map-navigator [mapState]="mapStateSvc"></ukis-map-navigator>

For examples see demo maps route-example-events

add the following dependencies to the package.json

• "@dlr-eoc/map-ol"
• "@dlr-eoc/map-tools"

add the following to the app.module.ts

import { MapOlModule } from '@dlr-eoc/map-ol';
import { MapToolsModule } from '@dlr-eoc/map-tools';

...

 imports: [
    ...
    MapOlModule,
    MapToolsModule
  ]

##Create simple map:

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

<main class="content-area">
  <ukis-map-ol [layersSvc]="layersSvc" [mapState]="mapStateSvc" [controls]="controls" id="olMap"></ukis-map-ol>
</main>

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 { IMapControls } from '@dlr-eoc/map-ol';

import { osm, eoc_litemap } from '@dlr-eoc/base-layers-raster';

controls: IMapControls;
  constructor(
    public layerSvc: LayersService,
    public mapStateSvc: MapStateService
) { }

ngOnInit() {
    this.addBaselayers();
}

addBaselayers() {
    const layers = [
        new osm({
        visible: false,
        legendImg: null
        }),
        new eoc_litemap({
        visible: true,
        legendImg: null
        })
    ];

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

##To add mouse position component:

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

<clr-vertical-nav [clrVerticalNavCollapsible]="true" [clr-nav-level]="2">
  <clr-vertical-nav-group [clrVerticalNavGroupExpanded]="false" class="layers" title="Coordinates">
    <cds-icon shape="compass" clrVerticalNavIcon></cds-icon>
    Coordinates
    <clr-vertical-nav-group-children class="padding title-ellipsis">
      <ukis-mouse-position></ukis-mouse-position>
    </clr-vertical-nav-group-children>
  </clr-vertical-nav-group>
</clr-vertical-nav>

##To add projection switch component (with 3 predefined projections):

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

<clr-vertical-nav-group [clrVerticalNavGroupExpanded]="false" class="layers" title="Projection">
    <cds-icon shape="map" clrVerticalNavIcon></cds-icon>
    Projection
    <clr-vertical-nav-group-children class="padding title-ellipsis">
      <ukis-projection-switch [mapSvc]="mapSvc" [projectionList]="projections" [fitViewToNewExtent]="true" [mapStateSvc]="mapStateSvc"></ukis-projection-switch>
    </clr-vertical-nav-group-children>
  </clr-vertical-nav-group>

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

import { IProjDef } from '@dlr-eoc/map-tools'

projections: IProjDef[];

constructor(
    public layerSvc: LayersService,
    public mapStateSvc: MapStateService
) { 

    const arcticPolarStereographic: IProjDef = {
      code: 'EPSG:3995',
      proj4js: '+proj=stere +lat_0=90 +lat_ts=71 +lon_0=0 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs +type=crs',
      title: 'Arctic Polar Stereographic',
      extent: [-3299207.53, -3333134.03, 3299207.53, 3333134.03],
      worldExtent: [-180.0, 60.0, 180.0, 90.0],
      global: true,
      units: 'm'
    };

    const antarcticPolarStereographic: IProjDef = {
      code: `EPSG:3031`,
      proj4js: '+proj=stere +lat_0=-90 +lat_ts=-71 +lon_0=0 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs +type=crs',
      title: 'Antarctic Polar Stereographic',
      extent: [-3299207.53, -3333134.03, 3299207.53, 3333134.03],
      worldExtent: [-180.0, -90.0, 180.0, -60.0],
      global: true,
      units: 'm'
    };

    const webMercator: IProjDef = {
      code: `EPSG:3857`,
      proj4js: '+proj=merc +a=6378137 +b=6378137 +lat_ts=0 +lon_0=0 +x_0=0 +y_0=0 +k=1 +units=m +nadgrids=@null +wktext +no_defs +type=crs',
      title: 'Spherical Mercator',
      extent: [-20037508.34, -20048966.1, 20037508.34, 20048966.1],
      worldExtent: [-180.0, -85.06, 180.0, 85.06],
      global: true,
      units: 'm'
    };

    this.projections=[webMercator, arcticPolarStereographic, antarcticPolarStereographic];
}

##To add navigator component:

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

<clr-vertical-nav-group [clrVerticalNavGroupExpanded]="true" class="layers" title="Navigator">
    <cds-icon shape="compass" clrVerticalNavIcon></cds-icon>
    Navigator
    <clr-vertical-nav-group-children class="padding title-ellipsis">
      <ukis-map-navigator [mapState]="mapStateSvc"></ukis-map-navigator>
    </clr-vertical-nav-group-children>
  </clr-vertical-nav-group>
