map not loading because venure service version is not supported - here-api

I'm getting an error that venue service version 1 is no longer supported.
I'm using version 3.1.3.5 of the javascript version of Here.
Is there a newer version that I need to switch to?

The latest version for Maps API for JavaScript is 3.1.30.16. We would suggest you to upgrade the version.
For more help on Indoor Maps with JS API, please refer to the updated guide at https://developer.here.com/documentation/indoor-map/user_guide/topics/indoor-jsapi.html
You can also refer to an example at https://jsfiddle.net/y1wq98hm/
venuesService.loadVenue('7348').then((venue) => {
// add Indoor Maps data to the Indoor Maps provider
venuesProvider.addVenue(venue);
venuesProvider.setActiveVenue(venue);
// create a tile layer for the Indoor Maps provider
map.addLayer(new H.map.layer.TileLayer(venuesProvider));
// Set center of the map view to the center of the venue
map.setCenter(venue.getCenter());
// optionally select a different level
venue.setActiveDrawing(7880);
// create a level control
const levelControl = new H.venues.ui.LevelControl(venue);
ui.addControl('level-control', levelControl);
// create a drawing control:
const drawingControl = new H.venues.ui.DrawingControl(venue);
ui.addControl('drawing-control', drawingControl);
});
}
var platform = new H.service.Platform({
apikey: window.apikey
});
var defaultLayers = platform.createDefaultLayers();
// Step 2: initialize a map
var map = new H.Map(document.getElementById('map'), defaultLayers.vector.normal.map, {
zoom: 18,
center: { lat: 47.452353, lng: 8.562455 },
pixelRatio: window.devicePixelRatio || 1
});
// add a resize listener to make sure that the map occupies the whole container
window.addEventListener('resize', () => map.getViewPort().resize());
// Step 3: make the map interactive
// MapEvents enables the event system
// Behavior implements default interactions for pan/zoom (also on mobile touch environments)
var behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(map));
// Step 4: create the default UI component, for displaying bubbles
var ui = H.ui.UI.createDefault(map, defaultLayers);
// Step 5: add the Indoor Map
addVenueToMap(map);

initMap Error: Couldn't create WebGL context

I'm developing an angular web app and after migrating HERE maps from 3.0 to 3.1 got a problem rendering the new version of the map.
The following error:
initMap Error: Couldn't create WebGL context.
The HERE Maps API for JavaScript version 3.1 contains a new default rendering engine.The engine uses an HTML5 WebGL canvas element and enables rendering of rich and customizable vector maps. In order to make the most of the WebGL engine, use the new vector tiles.
The snippet below shows how to switch to the vector tiles:
// Obtain the default map types from the platform object:
var defaultLayers = platform.createDefaultLayers();
// Instantiate (and display) a map object:
var map = new H.Map(
document.getElementById('mapContainer'),
defaultLayers.vector.normal.map,
{
zoom: 10,
center: { lat: 52.5, lng: 13.4 }
});

Google Maps and Location

I'm building an application using CakePHP that will store events including the event location. When a user visits the application they will see a Google Map that will get their location and show events near them in the form of little pins that they can click on to view the event details.
I have some questions though:
1.) How would I store the Location in the DB? Would the actual geolocation coordinates be the best bet and how would I make it easy for a user to create an event and enter them.
2.) Once I have the events in place how do I create custom pins with the info pulled from the DB? Example like foursquare:
3.) Whilst getting the users location using HTML5 Geolocation how do I show a little loader on the map again like Foursquare does?
So far I've managed to create the Map and make the controls minified and get the location of the viewer but I'm not sure how do 3 and show a better feedback to the user for the geolocation.
If someone could help me with those other two questions as well it'd be very much appreciated as I'm finding it very confusing so far. Thanks.
var map;
function initialize() {
var myOptions = {
zoom: 8,
panControl: false,
zoomControl: true,
zoomControlOptions: {
style: google.maps.ZoomControlStyle.SMALL
},
mapTypeControl: false,
scaleControl: false,
streetViewControl: false,
overviewMapControl: false,
center: new google.maps.LatLng(-34.397, 150.644),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map_canvas'),
myOptions);
// Try HTML5 geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var infowindow = new google.maps.InfoWindow({
map: map,
position: pos,
content: 'Location found using HTML5.'
});
map.setCenter(pos);
}, function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
function handleNoGeolocation(errorFlag) {
if (errorFlag) {
var content = 'Error: The Geolocation service failed.';
} else {
var content = 'Error: Your browser doesn\'t support geolocation.';
}
var options = {
map: map,
position: new google.maps.LatLng(60, 105),
content: content
};
var infowindow = new google.maps.InfoWindow(options);
map.setCenter(options.position);
}
google.maps.event.addDomListener(window, 'load', initialize);
1) Store the actual coordinates of the location and any extra meta data (if you have it) like place name, foursquare_id, date, etc. Storing it this way will make using the data later on straightforward, such as plotting on a map or location name lookup. This will be your Location model.
Create an Event model which you can then associate to a Location. You could hack together some nice interactive functionality using event handlers on your map markers.
Something like: "the user clicks a location on the map, up pops a box asking them would like like to create a new event at this location, marker is added to the map and a form appears where they can populate the event details, etc, etc." You get the idea.
Have a look at the Marker documentation.
2) You can set a custom image for the map markers using ImageMarker Class. Take a look at the huge set of examples for ideas of what's possible.
3) The navigator.geolocation.getCurrentPosition() method as I understand it, is asynchronous. The first argument is the successCallback.
With this in mind, you could set an overlay on your map: "Finding your location", then make the call to getCurrentPosition(). In your successCallback function, you would then hide the overlay.

When is remove_at event in Google Maps API v3 triggered?

I am working on google map api v3 and want to add a feature of editing the polyline. As of the google documentation. There are 3 events fired when a polyline is in edit mode.
insert_at
set_at
remove_at
I know when first two events are fired and am able to get the edited coordinates as well. I also want to delete a node but not sure how it works?. Can anyone tell me when will the event "remove_at" will be fired ?
According to the documentation these events belong to class google.maps.MVCArray. You can find there also a description of remove_at event:
This event is fired when removeAt() is called. The event passes the
index that was passed to removeAt() and the element that was removed
from the array.
But I'm not sure you can use these events to handle changes while editing the Polyline. That's very interesting, please let us know if it works and how!
'remove_at' will be triggered when you undo an edit to an existing overlay that results in control point(s) getting removed.
I've created a fiddle to demonstrate this.
From the fiddle:
var myLatlng = new google.maps.LatLng(60.629765, 6.424094);
var myOptions = {
zoom: 14,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var drawMan = new google.maps.drawing.DrawingManager({
map: map,
drawingControl: false,
polygonOptions: {
editable: true,
draggable: true
}
});
drawMan.setDrawingMode(google.maps.drawing.OverlayType.POLYGON);
google.maps.event.addListener(drawMan, 'overlaycomplete', function (event) {
// When draw mode is set to null you can edit the polygon you just drawed
drawMan.setDrawingMode(null);
google.maps.event.addListener(event.overlay.getPath(), 'remove_at', function () {
alert('remove_at triggered');
});
});

google maps v2 to v3: roadmap getTile() why doesn't work?

Why this v2-like construction doesn't work in v3?
(instead roadmap tile path I get undefined)
var mytype = new google.maps.ImageMapType({
getTileUrl: function(tile, zoom) {
var url = '';
if (cond_need_custom_tiles) {
url = 'http://domain.com/mytiles/tile-'+tile.x+'-'+tile.y+'-'+zoom;
}
else { // need ROADMAP tiles
// old (v2):
// url = G_NORMAL_MAP.getTileLayers()[0].getTileUrl(tile, zoom);
// new (v3):
url = map.mapTypes.get(google.maps.MapTypeId.ROADMAP).getTile(tile, zoom); // why it doesn't work??
}
console.log(url); // undefined!!! why?
return url;
},
tileSize: new google.maps.Size(256, 256),
minZoom: 0,
maxZoom: Number(opt.zoom),
name: 'mytiles',
});
PS: I want my tiles mapType and ROADMAP in background (where no my tiles), thanks.
getTile() is no longer defined for basemaps; it should be used only as a user defined method on custom mapTypes -- please see comment #2 of http://code.google.com/p/gmaps-api-issues/issues/detail?id=3635#c2 for some additional details.
In your particular use case, perhaps you can simply always load the ROADMAP tiles by default, and then display your custom imageMapType as appropriate depending on cond_need_custom_tiles ?
Alternatively the bug noted above would be a good place to provide additional details on your use case.

jQuery Mobile + jQuery UI google maps + Fusion Markers

this has been baking my noodle for months, I'll be honest, I am a designer not a programmer so this type of scripting is a bit harder than the average jquery/javascript that I'm used too.
I can't find any basic documentation on how to implement it, apart from this but it's not massively intuitive - http://jquery-ui-map.googlecode.com/svn/trunk/demos/jquery-mobile-example.html
I've tried making a JSfiddle, but I can't even get it to work (now working thanks to Tsar)
I've built a jQuery mobile app and I'm desperate to get the geo-location functionality working with fusion table markers (from my fusion table) and to be allowed to click on the fusion table markers to reveal a info window. This info window will be constructed in fusion tables.
I need the geo-location to center the map on the devices current location - if the geo-location is not available or denied by device user, then the map needs to be centered on these co-ordinates 52.450939, -1.721002.
What would be the next level is to have the the jQuery mobile UI pop-up window but this is not critical, just the standard bubble on the map is fine.
A updated JSFiddle... http://jsfiddle.net/twGHC/30/
My fusion table number is: 1260763
Default location is: (only if Geo location is not available) 52.450939, -1.721002
Zoom level: 13
Any advice would be awesome, please feel free to JSfiddle it. Thanks in advance.
Here's a working solution, which detects user's location, drops a marker on it and plots the map with your Fusion Markers. As per Google Maps v3 API documentation:
$(function() {
var position = new google.maps.LatLng(52.450939, -1.721002);
getCurrentPosition = function(callback) {
// Try W3C Geolocation (Preferred)
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(
function(pos) {
position = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude);
callback(position);
}, callback(position));
} // Try Google Gears Geolocation
else if (google.gears) {
var geo = google.gears.factory.create('beta.geolocation');
geo.getCurrentPosition(
function(pos) {
position = new google.maps.LatLng(pos.latitude,pos.longitude);
callback(position);
}, callback(position));
} // Browser doesn't support Geolocation
else {
// Drop the user off in Coventry =)
callback(position);
}
};
// call the above function
getCurrentPosition(InitMap);
});
function InitMap(pos) {
map = new google.maps.Map(document.getElementById('map_canvas'), {
center: pos,
zoom: 14,
mapTypeId: 'roadmap'
});
var marker = new google.maps.Marker({
position: pos,
animation: google.maps.Animation.DROP,
map: map,
title: "You are here, mate!"
});
var layer = new google.maps.FusionTablesLayer({
query: {
select: 'Geocodable address',
from: '1260763'
},
});
layer.setMap(map);
};
When user denies tracking of his location, exception is caught in getCurrentPosition, however, 2nd optional parameter in this function is an exception handler, so what I did is simply passed in callback(position) so that default location sets on the map. If you don't want to do it, move out the map initializer code from InitMap into separate function and call it instead, when exceptions are caught, to display a blank map.
See it in action here: http://jsfiddle.net/twGHC/36/
P.S. In case your next question is "how to add a balloon pop-up on marker click", here's what you need to do.
Here is how to do it with jquery-ui-map:
http://jsfiddle.net/rweCf/1/
http://jsfiddle.net/rweCf/1/embedded/result/
If you just want to change within a certain radius of the client position this is how you would do it
http://jsfiddle.net/Ywknf/1/ (client location is the initial point so everyone can see the results)
Here is the code if the url isnt working or the trunk code changed
$(function() {
$('#map_canvas').gmap({'center': '52.450939, -1.721002', 'zoom': 10, 'disableDefaultUI': true, 'mapTypeId': 'terrain'}).bind('init', function(event, map) {
$('#map_canvas').gmap('getCurrentPosition', function(results, status) {
if ( status === 'OK' ) {
var position = new google.maps.LatLng(results.coords.latitude, results.coords.longitude);
var marker = $('#map_canvas').gmap('get', 'markers > client' );
if ( !marker ) {
$('#map_canvas').gmap('addMarker', { 'id': 'client', 'position': position, 'bounds': true });
} else {
marker.setPosition(position);
map.panTo(position);
}
} else if ( status === 'NOT_SUPPORTED' ) {
$('#map_canvas').gmap('addMarker', { 'id': 'client', 'position': $('#map_canvas').gmap('get', 'map').getCenter(), 'bounds': true });
}
});
$('#map_canvas').gmap('loadFusion', { 'query': { 'select': 'Geocodable address', 'from': 1260763 } } );
});
});
