React Binding Geographic Data Models

The Ignite UI for React map component is designed to display geo-spatial data from shape files and/or geographic locations from data models on geographic imagery maps. The DataSource property of geographic series is used for the purpose of binding to data models. This property can be bound an array of custom objects.

React Binding Geographic Data Models Example

The following table summarized data structures required for each type of geographic series:

Code Snippet

The following code shows how to bind the IgrGeographicSymbolSeries to a custom data model that contains geographic locations of some cities of the world stored using longitude and latitude coordinates. Also, we use the IgrGeographicPolylineSeries to plot shortest geographic path between these locations using the WorldUtility

import { IgrGeographicSymbolSeries } from 'igniteui-react-maps';
import { IgrGeographicPolylineSeries } from 'igniteui-react-maps';
import WorldUtils from "./WorldUtils" ;
// ...

constructor(props: any) {
    super(props);

    const cityDAL = { lat:  32.763, lon: -96.663, country: "US", name: "Dallas" };
    const cityNZL = { lat: -36.848, lon: 174.763, country: "New Zealand", name:"Auckland" };
    const cityCHL = { lat: -33.475, lon: -70.647, country: "Chile", name:"Santiago" };
    const cityJAP = { lat:  35.683, lon: 139.809, country: "Japan", name: "Tokyo" }
    const citySNG = { lat:  1.229, lon: 104.177,  country: "Singapore", name:"Singapore" };
    const cityMOS = { lat: 55.750, lon:  37.700,  country: "Russia", name: "Moscow"};

    this.flights = [
        { origin: cityDAL, dest: citySNG, color: "Green" },
        { origin: cityMOS, dest: cityNZL, color: "Red" },
        { origin: cityCHL, dest: cityJAP, color: "Blue" },
    ];

    for (const flight of this.flights) {
        this.createPolylineSeries(flight);
        this.createSymbolSeries(flight);
    }
}

public createSymbolSeries(flight: any)
{
    const geoLocations = [flight.origin, flight.dest ];
    const symbolSeries = new IgrGeographicSymbolSeries ( { name: "symbolSeries" });
    symbolSeries.dataSource = geoLocations;
    symbolSeries.markerType = MarkerType.Circle;
    symbolSeries.latitudeMemberPath = "lat";
    symbolSeries.longitudeMemberPath = "lon";
    symbolSeries.markerBrush  = "White";
    symbolSeries.markerOutline = flight.color;
    symbolSeries.thickness = 1;
    this.geoMap.series.add(symbolSeries);
}

public createPolylineSeries(flight: any)
{
    const geoPath = WorldUtils.calcPaths(flight.origin, flight.dest);
    const geoDistance = WorldUtils.calcDistance(flight.origin, flight.dest);
    const geoRoutes = [ { points: geoPath } ];
    const lineSeries = new IgrGeographicPolylineSeries ( { name: "lineSeries" });
    lineSeries.dataSource = geoRoutes;
    lineSeries.shapeMemberPath = "points";
    lineSeries.shapeStrokeThickness = 9;
    lineSeries.shapeOpacity = 0.5;
    lineSeries.shapeStroke = flight.color;
    this.geoMap.series.add(lineSeries);
}
