• IOS

Installation

    npm i mapmyindia-map-cordova-ionic-beta 

• Add this plugin to your app's module(app.module.ts) and also include as a provider if you are using IONIC V>1 ie. below

import { mmi } from 'mapmyindia-map-cordova-ionic-beta';
@NgModule({
  ...

  providers: [
    ...
    mmi
    ...
  ]
  ...
})
export class AppModule { }

Features

General Usage

import { mmi } from 'mapmyindia-map-cordova-ionic-beta';

...

constructor(private maps: mmi) {} //Useful for Ionic

or 

this.maps=new mmi(); 

Events

1. MapLoad

loadmap method needs two parameters to initialize a map in SDK

1. Map div #id // with proper css width & height
2. Map parameters
   • Key<sup>*</sup>: your api map key from Mapmyindia (mandatory)
   • Zoomcontrol
   • Search control
   • center centre map to a geoposition e.g. center:[25.5454,77.54545]
   • Location control
     • For better GPS location add cordova geolocation plugin: cordova plugin add cordova-plugin-geolocation

    var load_maps=this.maps.loadMaps('map',{key:'<map key>',zoom:{control:true},location:{control:true,initial:true,bounds:true}});

Controls

1. Zoom

Zoom control can be controlled by using the following parameter:

• zoom number between 4 to 18 //To show initial map zoom e.g. zoom:15
• control //To show or hide the zoom control; takes boolean values e.g. control:true
• position:[topPosition,leftPosition] To change the position of the control The topPosition or leftPosition can be absolute values in pixels or relative values in percentage e.g. position:['150px','200px'] OR position:['10%','20%']

2. Location

A location control provides a button that uses the GPS geolocation API to locate the user on the map.

• control //To show or hide the zoom control; takes boolean values. e.g. control:true
• initial default false; to call location on map load; takes boolean values. e.g. initial:true
• zoom set any any initial zoom on location; takes integer zoom levels from 4 to 17.
• bounds set location bound with center to default level zoom 16.
• html icon (html) for showing location on map.
• position:[topPosition,leftPosition] To change the position of the control The topPosition or leftPosition can be absolute values in pixels or relative values in percentage e.g. position:['150px','200px'] OR position:['10%','20%']

Example of using location

location:{control:true, initial:true, zoom:12}

Tip: For better GPS location use cordova geolocation plugin cordova plugin add cordova-plugin-geolocation

3. Scale

A map scale represented as a unitless factor (e.g. 1:50000) means that a single map unit represents X real world units (e.g. a meter in the map = 50 km in reality). To show scale on the maps, scale control can be used; which has the following parameters:

• scaledefault false; to show scale; takes boolean values. e.g. initial:true
• position:[topPosition,leftPosition] To change the position of the control The topPosition or leftPosition can be absolute values in pixels or relative values in percentage e.g. position:['150px','200px'] OR position:['10%','20%']#### 4. Map Layers

1. Hybrid

Hybrid maps can be shown or hidden with the help of a method call. Hybrid maps are satellite maps overlayed with MapmyIndia Map labels and transportation network.

• Show hybrid map

this.maps.hybrid (true);

• Hide hybrid maps

this.maps.hybrid (false);

2. Traffic

Traffic layer can be shown or hidden with the help of a method call. Traffic layer is the traffic flow overlay within MapmyIndia Maps that shows the flow of traffic on road segments. This overlay is available only for paid customers.

• Show traffic layer

this.maps.traffic (true);

• Hide traffic layer

this.maps.traffic (false);

3. Removing Map layers

Removing a layer can be made possible by default leaflet method or by MapmyIndia SDK method

• By leaflet method:

mapss.removeLayer(map_marker);

• By SDK method:

this.maps.removeLayer(map_marker);

or

map_marker.remove();

Overlays

1. Markers

We support leaflet marker method for adding markers in app.

this.maps.L.marker([28.5, 77.5]).addTo(map object);

Adding markers via Custom marker method

var marker=this.maps.marker(mrker_arr,
    {
	    iconUrl:"assets/imgs/logo.png", iconSize:[36,51],popupAnchor:[0,-16],draggable:true,fitbounds:true,cluster:true
	 });

Parameters:

1. Marker Object: (mandatory) it can be single array with lat, long;

var mrker_arr= [28.5454,77.545454];

Other Optional Parameters within array for single & group markers:

• tooltip
• popup
• divicon
• events

example:

var mrker_arr= [28.5454,77.545454,{tooltip:"this is first popup",popup:"this is first popup",divicon:"<img src='https://maps.mapmyindia.com/images/3.png'>",event:["click",function(e){console.log(e)}]}];

With multiple markers array

var mrker_arr= [
[28.5454,77.545454,{tooltip:"this is first popup",popup:"this is first popup",divicon:"<img src='https://maps.mapmyindia.com/images/3.png'>",event:["click",function(e){console.log(e)}]}]
[28.5454,77.145454],
[28.5450,77.145450],
[28.2454,77.145454],
[26.5454,77.145454]
];

Marker By GeoJSON array

var mrker_arr = {
"type":"FeatureCollection",
"features":[
{
"type":"Feature",
"geometry":{
"type":"Point",
"coordinates":[
78.3613558,
28.8044875
]
},
"properties":{
"popup":"this is geojson point 1",
"icon":{
"icon_url":"assets/imgs/logo.png"
}
}
},
{
"type":"Feature",
"geometry":{
"type":"Point",
"coordinates":[
78.3613558,
27.8044875
]
},
"properties":{
"popup":"this is geojson point 2",
"icon":{
"icon_url":"assets/imgs/logo.png"
}
}
}
]
};

2. Marker Options

You can use all leaflet option for marker like:

{iconUrl:"assets/imgs/logo.png", iconSize:[36,51],popupAnchor: [0,-16],draggable:true,fitbounds:true,cluster:true}

Example:

var marker=this.maps.marker(mrker_arr,{iconUrl:"assets/imgs/logo.png", iconSize:[36,51],popupAnchor:[0, -16],draggable:true,fitbounds:true,cluster:true});

Icon: Supported leaflet Icon method with all options

i.e.

icon:this.maps.L.icon({iconUrl: 'assets/imgs/logo.png',iconSize:[36, 51]})

Or

iconUrl:"assets/imgs/logo.png"

fitbounds:true/false** /*to fit map bounds  according to all markers*/

rotationAngle:angle //ie rotationAngle:90

cluster:true/false

Or use custom options for clustering

cluster:{
className:"grp"/*to all css accordingly*/,
polygonOptions: {
fillColor: '#111',
color: '#000',
weight: 0.5,
opacity: 1,
fillOpacity: 0.5
}
}

You can Add Tooltip & Info Window separately:

• Add tooltip:

marker.bindTooltip("my tooltip text").openTooltip();

• Add Popup:

marker.bindPopup("my tooltip text");

3. Marker Events:

Event	Description
dragstart	Fired when the user starts dragging the marker.
movestart	Fired when the marker starts moving (because of dragging).
drag	Fired repeatedly while the user drags the marker.
dragend	Fired when the drag event ends.
moveend	Fired when movement of the map under marker stops.
click	Fired when the user taps on the marker on map.

Example:

marker.on('click',function(e){console.log(e)})

2. Polylines

MapmyIndia Hybrid SDK offers a class for drawing polyline overlays on a map. Leaflet Properties & Events are also supported in our Hybrid SDK as illustrated in the following code snippet.

var pts = [
[28.51, 78.68],
[27.77, 77.43],
[28.04, 78.2]
];

var polyline = this.maps.L.polyline(pts, {color: 'red'}).addTo(mapss);
mapss.fitBounds(polyline.getBounds());

Using Custom method for Polylines

This has some additional parameters to manage:

1. Points: it can be simple points array or geoJSON array.
2. Options: All Leaflet options with additional parameters.
   • fitbounds:true/false (can take either boolean value)
   • tooltip:text (replace 'text' with whatever tooltip you wish to use.
   • popup:text/html (Use a simple text or HTML as popup)
   • openpopup:true/false (control the behaviour of pop when HTML onload event is fired)
   • decorator

Example:

var pts = [[28.551042,77.268953],[28.551005,77.268649],[28.550986,77.268392],[28.550967,77.268231],[28.550967,77.268177],[28.550958,77.268016],

var polyline=this.maps.polyline(pts,{weight:7,color:"green",fitbounds:true,tooltip:"polyline tooltip",popup:"this is first popup",openpopup:false});

Events on Polylines

All Leaflet Events supported.

Example:

polyline.on('click',function(e){alert(e)})

GeoJSON Polyline

GeoJSON format for Polylines is also supported with MapmyIndia Hybrid Maps SDK.

Sample code snippet for GeoJSON polyline:

var latlngs={

};

Style for geoJSON polyline

Sample code snippet for styling a GeoJSON polyline

var style=function(feature) 
{
switch (feature.properties.tType) {
case 'slow': return {color: "red"};
case 'medium':  return {color: "yellow"};
default:return {color: "green"};}
};

var polyline=this.maps.polyline(latlngs,{style:style,weight:5,fitbounds:true});

Removing a polyline

polyline.remove();

Animated / Decorated Polyline

Use below option to show decorated polyline:

decorator:{icon:{iconUrl:'assets/imgs/car.png',iconSize:[14, 33],speed:20 /*range between 0-100*/}}
var polyline=this.maps.polyline(pts,{weight:7,color:"green",fitbounds:true,decorator:{icon:{iconUrl: 'assets/imgs/car.png',iconSize: [14, 33],speed:20}}});

3. Circles

MapmyIndia Hybrid SDK offers a class for drawing circle overlays on a map.

Addition of Circles

Code Snippet:

this.maps.L.circle([27.11, 77.5], {radius: 200}).addTo(mapss);

Leaflet Properties & Events related to circles are also supported in our Hybrid SDK.

4. Polygons

MapmyIndia Hybrid SDK offers a class for drawing polygon overlays on a map.

Addition of Polygons

Code Snippet:

var pl_pts = [[27, 79.05],[26.767, 78.03],[26.545, 78.05],[27.5454, 77.04]];

var polygon = this.maps.L.polygon(pl_pts, {color: 'red'}).addTo(mapss);

mapss.fitBounds(polygon.getBounds());

Leaflet Properties & Events for polygons thus added are also supported in our Hybrid SDK.

Adding tooltips to Polygons

polygon.bindTooltip("This is first tooltip");
