Map provider in EJ2 TypeScript Maps control
27 Apr 202315 minutes to read
The OpenStreetMap (OSM) is the online Maps provider built by a community of developers; it is free to use under an open license. It allows to view geographical data in a collaborative way from anywhere on the earth. The OSM Maps provides small tile images based on our requests and combines those images into a single image to display the Maps area in the Maps component.
Adding OpenStreetMap
The OSM Maps can be rendered using the urlTemplate property.
import { Maps } from '@syncfusion/ej2-maps';
let map: Maps = new Maps({
layers: [
{
urlTemplate:"https://tile.openstreetmap.org/level/tileX/tileY.png"
}
]
});
map.appendTo('#element');<!DOCTYPE html>

The OSM tile server can be changed by setting the tile URL in the urlTemplate property. For more details about the OSM tile server, refer here.
Enabling zooming and panning
The OSM Maps layer can be zoomed and panned. Zooming helps to get a closer look at a particular area on a Maps for in-depth analysis. Panning helps to move a Maps around to focus the targeted area.
import { Maps , Zoom} from '@syncfusion/ej2-maps';
Maps.Inject(Zoom);
let map: Maps = new Maps({
zoomSettings: {
enable: true,
toolbars: ["Zoom", "ZoomIn", "ZoomOut", "Pan", "Reset"]
},
layers: [
{
urlTemplate:"https://tile.openstreetmap.org/level/tileX/tileY.png"
}
]
});
map.appendTo('#element');<!DOCTYPE html>

</html>Adding markers and navigation line
Markers can be added to the layers of OSM Maps by setting the corresponding location’s coordinates of latitude and longitude using markerSettings. Navigation lines can be added on top of an OSM Maps layer for highlighting a path among various places by setting the corresponding location’s coordinates of latitude and longitude in the navigationLineSettings.
import { Maps, NavigationLine, Marker, Zoom } from '@syncfusion/ej2-maps';
Maps.Inject(NavigationLine, Marker, Zoom);
let map: Maps = new Maps({
zoomSettings: {
zoomFactor: 4
},
centerPosition: {
latitude: 29.394708,
longitude: -94.954653
},
layers: [
{
urlTemplate:"https://tile.openstreetmap.org/level/tileX/tileY.png",
markerSettings: [{
visible: true,
height: 25,
width: 15,
dataSource: [
{
latitude: 34.060620,
longitude: -118.330491,
name: "California"
},
{
latitude: 40.724546,
longitude: -73.850344,
name: "New York"
}
]
}],
navigationLineSettings: [{
visible: true,
color: "blue",
width: 5,
angle: 0.1,
latitude: [34.060620, 40.724546],
longitude: [-118.330491,-73.850344]
}]
}
]
});

</html>Adding sublayer
Any GeoJSON shape can be rendered as a sublayer on top of the OSM Maps layer for highlighting a particular continent or country in OSM Maps by adding another layer and specifying the type property of Maps layer to SubLayer.
import { Maps } from '@syncfusion/ej2-maps';
import { Africa_Continent } from './Africa_Continent.ts';
let map: Maps = new Maps({
layers: [
{
urlTemplate:"https://tile.openstreetmap.org/level/tileX/tileY.png"
},
{
shapeData: Africa_Continent,
type: 'SubLayer',
shapeSettings: {
fill: "blue"
}
}
]
});

</html>Enabling legend
The legend can be added to the tile Maps by setting the visible property of legendSettings to true.
import { Maps, Legend, Marker } from '@syncfusion/ej2-maps';
import { markerDataSource } from './markerdata.ts';
Maps.Inject(Legend, Marker);
let map: Maps = new Maps({
legendSettings: {
visible: true,
type: 'Markers',
useMarkerShape:true,
toggleLegendSettings: {
enable: true,
applyShapeSettings: false,
border: {
color: 'green',
width: 2
}
}
},
layers: [
{
urlTemplate:"https://tile.openstreetmap.org/level/tileX/tileY.png",
shapeDataPath: 'name',
shapePropertyPath: 'name',
shapeSettings: {
fill: '#E5E5E5'
},
markerSettings: [
{
dataSource: markerDataSource,
colorValuePath: 'color',
shapeValuePath:'shape',
legendText: 'country',
visible: true
}
]
}
]
});
