Imagery

This repo show you how to use @ansyn/imagery @ansyn/imagery-ol @ansyn/cesium packages to create a fast map web app of your own.

Installation

Inside your angular project run

  npm install @ansyn/imagery @ansyn/imagery-ol @angular/material @angular/cdk @types/geojson @ngx-translate/core@~10.0.2

or

 yarn add @ansyn/imagery @ansyn/imagery-ol @angular/material @angular/cdk @types/geojson @ngx-translate/core@~10.0.2

Basic Usage

Show OpenLayers map with Bing provider

Step-1

Open app.module.ts file and change it content to:

import { NgModule } from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {ImageryModule, MAP_PROVIDERS_CONFIG, MAP_SOURCE_PROVIDERS_CONFIG} from '@ansyn/imagery';
import { OL_CONFIG, OpenLayerBingSourceProvider, OpenLayersMap } from '@ansyn/imagery-ol';
import {AppComponent} from './app.component';

@NgModule({
declarations: [
  AppComponent,
],
imports: [
  BrowserModule,
  ImageryModule.provide({
    maps: [OpenLayersMap],
    plugins: [],
    mapSourceProviders: [OpenLayerBingSourceProvider]
  }),
],
providers: [
  {
    provide: OL_CONFIG,
    useValue: {}
  },
  {
    provide: MAP_PROVIDERS_CONFIG,
    useValue: {
      openLayersMap: {
        defaultMapSource: 'BING'
      }
    }
  },
  {
    provide: MAP_SOURCE_PROVIDERS_CONFIG,
    useValue: {
      'BING': {
        key: '<YOUR-KEYS>',
        styles: ['AerialWithLabels']
      }
    }
  }
],
bootstrap: [AppComponent]
})
export class AppModule {
}

This will tell our app to use OpenLayers map with our Imagery component.

Step-2

Create a sample setting file IMAGERRY_SETTING.ts inside your root file

import { OpenlayersMapName } from '@ansyn/imagery-ol';
import { IMapSettings } from '@ansyn/imagery';

const IMAGERY_SETTINGS: IMapSettings = {
  id: 'id',
  worldView: {
    mapType: OpenlayersMapName,
    sourceType: 'BING'
  },
  flags: {},
  data: {
    position: {
      'extentPolygon': {
        'type': 'Polygon',
        'coordinates': [
          [
            [
              -180,
              90
            ],
            [
              180,
              90
            ],
            [
              180,
              -90
            ],
            [
              -180,
              -90
            ],
            [
              -180,
              90
            ]
          ]
        ]
      }
    }
  }
};

export default IMAGERY_SETTINGS;

and import it in your app.component.ts
for more information about the settings object click here

import { Component } from '@angular/core';
import { IMapSettings } from '@ansyn/imagery';
import IMAGERY_SETTINGS from './IMAGERY_SETTINGS';


@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.less']
})
export class AppComponent {
  public settings: IMapSettings = IMAGERY_SETTINGS;
}

Step-3

open app.component.html file and change it content to:

<div class="app">
  <div class="imagery">
      <div>
        <ansyn-imagery-view [settings]="settings"></ansyn-imagery-view>
      </div>
  </div>
</div>

Step-4

The Imagery component must have a height give it a style inside app.component.less

div.app {
  display: flex;
  position: relative;
  flex-direction: column;
  width: 100vw;
  height: 100vh;
  
.imagery {
  display: flex;
  flex: 1;
  box-sizing: border-box;
  padding: 50px 0;
}

/deep/ .ol-scale-line-inner {
    margin-top: 16px;
    min-width: 144px;
  }

  /deep/ .ol-mouse-position {
    bottom: 5px;
    top: auto;
    right: auto;
    padding-left: 13px;
    padding-bottom: 18px;
    color: #cccccc;
  }
}

you may also give him specific height

Step 5

add ol and material style to our global style.less

@import "~@angular/material/prebuilt-themes/indigo-pink.css";
@import "~ol/ol.css";
@import url("https://fonts.googleapis.com/icon?family=Material+Icons");

body {
  margin: 0;
}

Draw annotations on the map

Step-1

Import necessary modules

Open app.module.ts and change it content to:

import { NgModule } from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {ImageryModule, MAP_PROVIDERS_CONFIG, MAP_SOURCE_PROVIDERS_CONFIG} from '@ansyn/imagery';
-import { OL_CONFIG, OpenLayerBingSourceProvider, OpenLayersMap } from '@ansyn/imagery-ol';
+import { OL_CONFIG, OpenLayerBingSourceProvider, OpenLayersMap, OL_PLUGINS_CONFIG, AnnotationsVisualizer } from '@ansyn/imagery-ol';
import {AppComponent} from './app.component';

@NgModule({
  declarations: [
    AppComponent,
  ],
  imports: [
    BrowserModule,
    ImageryModule.provide({
      maps: [OpenLayersMap],
-      plugins: [],
+      plugins: [AnnotationsVisualizer],
      mapSourceProviders: [OpenLayerBingSourceProvider]
    })
  ],
  providers: [
+    {
+      provide: OL_PLUGINS_CONFIG,
+      useValue: {
+        Annotations: {}
+      }
+    },
    {
      provide: OL_CONFIG,
      useValue: {}
    },
    {
      provide: MAP_PROVIDERS_CONFIG,
      useValue: {
        openLayersMap: {
          defaultMapSource: 'BING'
        }
      }
    },
    {
      provide: MAP_SOURCE_PROVIDERS_CONFIG,
      useValue: {
        'BING': {
          key: '<YOUR-KEYS>',
          styles: ['AerialWithLabels']
        }
      }
    }
  ],
  bootstrap: [AppComponent]
})
export class AppModule {
}

this will be able you to do the following in `app.component.ts'

import {AfterViewInit, Component} from '@angular/core';
import {ImageryCommunicatorService, IMapSettings} from '@ansyn/imagery';
import {AnnotationsVisualizer} from '@ansyn/imagery-ol';
import {filter, take, tap} from 'rxjs/operators';
import IMAGERY_SETTINGS from './IMAGERY_SETTINGS';

@Component({
 selector: 'app-root',
 templateUrl: './app.component.html',
 styleUrls: ['./app.component.less']
})
export class AppComponent implements AfterViewInit {
 public settings: IMapSettings = IMAGERY_SETTINGS;
 annotations: AnnotationsVisualizer;

 constructor(protected communicators: ImageryCommunicatorService) {
 }

 onInitMap() {
   const communicator = this.communicators.provide(IMAGERY_SETTINGS.id);
   this.annotations = communicator.getPlugin(AnnotationsVisualizer);
   this.annotations.setMode('Polygon');
 }

 ngAfterViewInit() {
   this.communicators.instanceCreated.pipe(
     filter(({id}) => id === IMAGERY_SETTINGS.id),
     tap(this.onInitMap.bind(this)),
     take(1)
   ).subscribe();
 }
}

which give you the ability to draw one annotation of type polygon when the map load but we want to draw more than one annotation and be able to chose the type of the annotation.

Step-2

Create an Annotation control

create a component named annotations-control

  ng g c annotaions-control

install material-community-components for a color picker

  npm install material-community-components

open app.module.ts and change it content to:

import { NgModule } from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {ImageryModule, MAP_PROVIDERS_CONFIG, MAP_SOURCE_PROVIDERS_CONFIG} from '@ansyn/imagery';
import { OL_CONFIG, OpenLayerBingSourceProvider, OpenLayersMap, OL_PLUGINS_CONFIG, AnnotationsVisualizer } from '@ansyn/imagery-ol';
import {AppComponent} from './app.component';
import {AnnotationsControlComponent} from './annotations-control/annotations-control.component';
+import {MccColorPickerModule} from 'material-community-components';
+import {MatButtonModule, MatIconModule} from '@angular/material';
+import {BrowserAnimationsModule} from '@angular/platform-browser/animations';

@NgModule({
  declarations: [
    AppComponent,
    AnnotationsControlComponent
  ],
  imports: [
    BrowserModule,
+    BrowserAnimationsModule,
+    MatButtonModule,
+    MatIconModule,
+    MccColorPickerModule.forRoot({
+      used_colors: ['#000000', '#123456', '#777666']
+    }),
    ImageryModule.provide({
      maps: [OpenLayersMap],
      plugins: [AnnotationsVisualizer],
      mapSourceProviders: [OpenLayerBingSourceProvider]
    })
  ],
  providers: [
    {
      provide: OL_PLUGINS_CONFIG,
      useValue: {
        Annotations: {}
      }
    },
    {
      provide: OL_CONFIG,
      useValue: {}
    },
    {
      provide: MAP_PROVIDERS_CONFIG,
      useValue: {
        openLayersMap: {
          defaultMapSource: 'BING'
        }
      }
    },
    {
      provide: MAP_SOURCE_PROVIDERS_CONFIG,
      useValue: {
        'BING': {
          key: '<YOUR-KEYS>',
          styles: ['AerialWithLabels']
        }
      }
    }
  ],
  bootstrap: [AppComponent]
})
export class AppModule {
}

open annotations-control.components.html amd change it content to:

<div class="list">
  <button
    *ngFor="let mode of ANNOTATION_MODE_LIST"
    mat-button
    [disabled]="!annotations"
    color="primary"
    [class.mat-accent]="annotations?.mode === mode"
    (click)="draw(mode)">
    {{ mode }}
  </button>

  <button mat-icon-button (click)="clear()">
    <mat-icon aria-label="Example icon-button with a heart icon">delete</mat-icon>
  </button>

  <button mat-button>
    FILL
    <mcc-color-picker [selectedColor]="'#ffffff'"
                      (selected)="changeFill($event)"></mcc-color-picker>
  </button>

  <button mat-button>
    STROKE
    <mcc-color-picker [selectedColor]="'#ffffff'"
                      (selected)="changeStroke($event)"></mcc-color-picker>
  </button>

  <button mat-button>
    <input type="file" (change)="loadJSON($event.target.files)" />
  </button>
</div>

Open annotations-control.components.ts and change it content to:

import { Component, OnInit } from '@angular/core';
import IMAGERY_SETTINGS from '../IMAGERY_SETTINGS';
import { ImageryCommunicatorService } from '@ansyn/imagery';
import { ANNOTATION_MODE_LIST, AnnotationsVisualizer } from '@ansyn/imagery-ol';
import { fromEvent } from 'rxjs';
import { mergeMap, filter, take, tap } from 'rxjs/operators';

@Component({
  selector: 'app-annotations-control',
  templateUrl: './annotations-control.component.html',
  styleUrls: ['./annotations-control.component.less']
})
export class AnnotationsControlComponent implements OnInit {
  ANNOTATION_MODE_LIST = ANNOTATION_MODE_LIST;
  annotations: AnnotationsVisualizer;
  reader = new FileReader();

  onFileLoad$ = fromEvent(this.reader, 'load').pipe(
    mergeMap(() => {
      const readerResult: string = <string>this.reader.result;
      const geoJSON = JSON.parse(readerResult);
      const entities = this.annotations.annotationsLayerToEntities(geoJSON);
      return this.annotations.addOrUpdateEntities(entities);
    })
  );

  constructor(protected communicators: ImageryCommunicatorService) {
  }

  onInitMap() {
    const communicator = this.communicators.provide(IMAGERY_SETTINGS.id);
    this.annotations = communicator.getPlugin(AnnotationsVisualizer);
  }

  ngOnInit() {
    this.communicators.instanceCreated.pipe(
      filter(({ id }) => id === IMAGERY_SETTINGS.id),
      tap(this.onInitMap.bind(this)),
      take(1)
    ).subscribe();

    this.onFileLoad$.subscribe();
  }

  draw(mode) {
    this.annotations.setMode(this.annotations.mode === mode ? null : mode);
  }

  clear() {
    this.annotations.clearEntities();
  }

  changeFill(color) {
    this.annotations.updateStyle({ initial: { fill: color } });
  }

  changeStroke(color) {
    this.annotations.updateStyle({ initial: { stroke: color } });
  }

  loadJSON(files: FileList) {
    const file = files.item(0);
    if (file) {
      this.reader.readAsText(file, 'UTF-8');
    }
  }
}

Open annotations-control.component.less and change it content to:

:host {
  width: 100%;
  display: flex;
  justify-content: center;
  align-items: center;
  padding: 20px 0;
}

.list button {

  margin: 0 10px;
}

Step-3

Add our Annotation Control to our app

Open app.component.html and change it content to:

<div class="app">
  <div class="imagery">
    <div>
      <ansyn-imagery-view [settings]="settings"></ansyn-imagery-view>
    </div>
  </div>

+  <app-annotations-control></app-annotations-control>
</div>

you can read how to create your own plugin here

Draw icon at annotation center

The annotation plugin can draw an icon on the center of the annotation

Step-1

copy your icon inside the assets directory.

Step-2

in the app.module.ts add the path for the icon

import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { BrowserModule } from '@angular/platform-browser';
import { ImageryModule, MAP_PROVIDERS_CONFIG, MAP_SOURCE_PROVIDERS_CONFIG } from '@ansyn/imagery';
import { AnnotationsVisualizer, OL_CONFIG, OL_PLUGINS_CONFIG, OpenLayerBingSourceProvider, OpenLayersMap, AnnotationsContextMenuModule } from '@ansyn/imagery-ol';
import { NavbarModule } from './navbar/navbar.module';
import { AnnotationsControlComponent } from './annotations-control/annotations-control.component';
import { MatButtonModule, MatIconModule } from '@angular/material';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MccColorPickerModule } from 'material-community-components';

@NgModule({
  declarations: [
    AppComponent,
    AnnotationsControlComponent
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    NavbarModule,
    MatButtonModule,
    MatIconModule,
    MccColorPickerModule.forRoot({
      used_colors: ['#000000', '#123456', '#777666']
    }),
    ImageryModule.provide({
      maps: [OpenLayersMap],
      plugins: [AnnotationsVisualizer],
      mapSourceProviders: [OpenLayerBingSourceProvider]
    }),
    AnnotationsContextMenuModule
  ],
  providers: [
    {
      provide: OL_PLUGINS_CONFIG,
      useValue: {
-        Annotation: {}
+        Annotations: {
+          icon: {
+            src: 'assets/center-icon.svg'
+          }
+        }
      }
    },
    {
      provide: OL_CONFIG,
      useValue: {}
    },
    {
      provide: MAP_PROVIDERS_CONFIG,
      useValue: {
        openLayersMap: {
          defaultMapSource: 'BING'
        }
      }
    },
    {
      provide: MAP_SOURCE_PROVIDERS_CONFIG,
      useValue: {
        'BING': {
          key: '<YOUR-KEY>',
          styles: ['AerialWithLabels']
        }
      }
    }],
  bootstrap: [AppComponent]
})
export class AppModule {
}

Step-3

in annotation-control.component.html add a checkbox for hide/show icon

<div class="list">

+  <label>
+    show center icon
+      <input type="checkbox"
+         checked="showCenterIcon"
+        (change)="setCenterIcon()">
+  </label>
  <button
    *ngFor="let mode of ANNOTATION_MODE_LIST"
    mat-button
    [disabled]="!annotations"
    color="primary"
    [class.mat-accent]="annotations?.mode === mode"
    (click)="draw(mode)">
    {{ mode }}
  </button>

  <button mat-icon-button (click)="clear()">
    <mat-icon aria-label="Example icon-button with a heart icon">delete</mat-icon>
  </button>

  <button mat-button>
    FILL
    <mcc-color-picker [selectedColor]="'#ffffff'"
                      (selected)="changeFill($event)"></mcc-color-picker>
  </button>

  <button mat-button>
    STROKE
    <mcc-color-picker [selectedColor]="'#ffffff'"
                      (selected)="changeStroke($event)"></mcc-color-picker>
  </button>

  <button mat-button>
    <input type="file" (change)="loadJSON($event.target.files)" />
  </button>


</div>

Step-4

in annotation-control.component.ts add the follow:

import {Component, OnInit} from '@angular/core';
import {ImageryCommunicatorService} from '@ansyn/imagery';
import {ANNOTATION_MODE_LIST, AnnotationsVisualizer} from '@ansyn/imagery-ol';
import {fromEvent} from 'rxjs';
import {filter, mergeMap, take, tap} from 'rxjs/operators';
import IMAGERY_SETTINGS from '../IMAGERY_SETTINGS';

@Component({
  selector: 'app-annotations-control',
  templateUrl: './annotations-control.component.html',
  styleUrls: ['./annotations-control.component.less']
})
export class AnnotationsControlComponent implements OnInit {
  ANNOTATION_MODE_LIST = ANNOTATION_MODE_LIST;
  annotations: AnnotationsVisualizer;
  reader = new FileReader();

  onFileLoad$ = fromEvent(this.reader, 'load').pipe(
    mergeMap(() => {
      const readerResult: string = <string>this.reader.result;
      const geoJSON = JSON.parse(readerResult);
      const entities = this.annotations.annotationsLayerToEntities(geoJSON);
      return this.annotations.addOrUpdateEntities(entities);
    })
  );
+  showCenterIcon: boolean;

  constructor(protected communicators: ImageryCommunicatorService) {
  }

  onInitMap() {
    const communicator = this.communicators.provide(IMAGERY_SETTINGS.id);
    this.annotations = communicator.getPlugin(AnnotationsVisualizer);
+    this.showCenterIcon = this.annotations.isShowAnnotationCenter();
  }

  ngOnInit() {
    this.communicators.instanceCreated.pipe(
      filter(({id}) => id === IMAGERY_SETTINGS.id),
      tap(this.onInitMap.bind(this)),
      take(1)
    ).subscribe();

    this.onFileLoad$.subscribe();
  }

  draw(mode) {
    this.annotations.setMode(this.annotations.mode === mode ? null : mode);
  }

  clear() {
    this.annotations.clearEntities();
  }

  changeFill(color) {
    this.annotations.updateStyle({initial: {fill: color}});
  }

  changeStroke(color) {
    this.annotations.updateStyle({initial: {stroke: color}});
  }

  loadJSON(files: FileList) {
    const file = files.item(0);
    if (file) {
      this.reader.readAsText(file, 'UTF-8');
    }
  }

+  setCenterIcon() {
+    this.showCenterIcon = !this.showCenterIcon;
+    this.annotations.toggleAnnotaionCenerIndication(this.showCenterIcon);
+  }
}

Add Annotations edit menu

you may want to edit an annotation it been draw

Step-1

Open app.module.ts and change it content to:

import { NgModule } from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {ImageryModule, MAP_PROVIDERS_CONFIG, MAP_SOURCE_PROVIDERS_CONFIG} from '@ansyn/imagery';
-import { OL_CONFIG, OpenLayerBingSourceProvider, OpenLayersMap, OL_PLUGINS_CONFIG, AnnotationsVisualizer } from '@ansyn/imagery-ol';
+import { OL_CONFIG, OpenLayerBingSourceProvider, OpenLayersMap, OL_PLUGINS_CONFIG, AnnotationsVisualizer, AnnotationsContextMenuModule } from '@ansyn/imagery-ol';
import {AppComponent} from './app.component';
import {AnnotationsControlComponent} from './annotations-control/annotations-control.component';
import {MccColorPickerModule} from 'material-community-components';
import {MatButtonModule, MatIconModule} from '@angular/material';
import {BrowserAnimationsModule} from '@angular/platform-browser/animations';

@NgModule({
  declarations: [
    AppComponent,
    AnnotationsControlComponent
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    MatButtonModule,
    MatIconModule,
    MccColorPickerModule.forRoot({
      used_colors: ['#000000', '#123456', '#777666']
    }),
    ImageryModule.provide({
      maps: [OpenLayersMap],
      plugins: [AnnotationsVisualizer],
      mapSourceProviders: [OpenLayerBingSourceProvider]
-    })
+    }),
+    AnnotationsContextMenuModule
  ],
  providers: [
    {
      provide: OL_PLUGINS_CONFIG,
      useValue: {
        Annotations: {}
      }
    },
    {
      provide: OL_CONFIG,
      useValue: {}
    },
    {
      provide: MAP_PROVIDERS_CONFIG,
      useValue: {
        openLayersMap: {
          defaultMapSource: 'BING'
        }
      }
    },
    {
      provide: MAP_SOURCE_PROVIDERS_CONFIG,
      useValue: {
        'BING': {
          key: '<YOUR-KEYS>',
          styles: ['AerialWithLabels']
        }
      }
    }
  ],
  bootstrap: [AppComponent]
})
export class AppModule {
}

Open app.component.html and change it content to:

<div class="app">
  <div class="imagery">
    <div>
      <ansyn-imagery-view [settings]="settings"></ansyn-imagery-view>
+     <ansyn-annotations-context-menu [mapState]="settings"></ansyn-annotations-context-menu>
    </div>
  </div>
  <app-annotations-control></app-annotations-control>
</div>

now when you click on annotation you will be able
to change it color or stroke, and give it a label.
