Building OpenStreetMap into a WordPress Custom Plugin - javascript

I am building a WordPress plugin that involves the use of maps and user created custom markers. I want to separate the map from the marker so that a user can create custom markers cross map platform and keep the marker data on there WordPress page.
I set up a development server on a raspberry pi 3 B, with a 2 Terabyte hard drive that it boots from. I set up an OpenStreetMap tile server of North America to practice on and I got it up and through and html file in my /var/www/html that runs through a LAMP server that also includes my WordPress development web server.

});
// The location of our marker and popup. We usually think in geographic
// coordinates ('EPSG:4326'), but the map is projected ('EPSG:3857').
var myLocation = new OpenLayers.Geometry.Point(10.2, 48.9)
.transform('EPSG:4326', 'EPSG:3857');
// We add the marker with a tooltip text to the overlay
overlay.addFeatures([
new OpenLayers.Feature.Vector(myLocation, {tooltip: 'OpenLayers'})
]);
// A popup with some information about our location
var popup = new OpenLayers.Popup.FramedCloud("Popup",
myLocation.getBounds().getCenterLonLat(), null,
'<a target="_blank" href="http://openlayers.org/">We</a> ' +
'could be here.<br>Or elsewhere.', null,
true // <-- true if we want a close (X) button, false otherwise
);
// Finally we create the map
map = new OpenLayers.Map({
div: "map", projection: "EPSG:3857",
layers: [new OpenLayers.Layer.OSM(), overlay],
center: myLocation.getBounds().getCenterLonLat(), zoom: 15

}

</html>
This is an example of the example marker that I created which I can use a short code to link to in my plugin, but I can't get scripts to run in the plugin itself with results on the map.
For example when I run this script in my plugin attached to just a plain map.html iframe it doesn't do anything.

How to tune Azure Maps to get the corract location?

I am interested in Azure Maps' animation library. After setting up an account and initialized the map. I found out that the coordinates I put as parameters aren't the ones it shows.
For Example I currently live in Tunisia. So I've set up the center coordinates to (36.800697, 10.181198).
But, the map gets centered at Addis Ababa for some reason. I am currently following their code example "Animate marker along path". [Github link][1] As you can see I have set up a bunch of mock coordinates.
PS: In the following example, I will mask my key.

You inverted longitude and latitude. The azure-maps library expects the longitude first :
map = new atlas.Map('myMap', {
center: [10.305192, 36.817421],

view: 'Auto',

How to setup HERE Base Map Tiles API for HERE Javascript API?

I am succesfully implementing the HERE Javascript API for my web app. I wanted to lighten the map presentation, so I first tried to create my own map style as presented on this guide.
The examples given work fine but I could not tune it as I wish without malfunctioning (I guess indentation is the problem but I could not verify it despite hours of trying). I could not find any "Map styling file generator" so I almost gave up until I found these:
How to remove all colors from Here Maps base layer?; and
Here JavaScript 3.0 API - decent color scheme
Unfortunately, the given code in these answers does not work:
//Instead of using the default layers...
//var defaultLayers = platform.createDefaultLayers();
//...create your own layer (with e.g. the "reduced" scheme
var reduced = platform.getMapTileService({
type: 'base'
}).createTileLayer("maptile", "reduced.day", 256, "png8");
//Initialize a map using your custom map tile layer
var map = new H.Map(document.getElementById('mapp'), reduced, {
center: {
lat: 52.3,
lng: 13.8
},
zoom: 10
});
whereas the defaultLayers.vector.normal.map and the reduced objects seems to be the same kind of objects, using the defaultLayers get me the default map and using the reduced Layout just get me a blank map without errors on console but those GET type Errors:

///### Map Interaction
// Add a resize listener to make sure that the map occupies the whole container
window.addEventListener('resize', () => map.getViewPort().resize());
// Set the map interactive
// Behavior implements default interactions for pan/zoom (also on mobile touch environments)
var behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(map));
// Create the default UI:
var ui = H.ui.UI.createDefault(map, defaultLayers ,'es-ES');
Maybe the statement for getting Map Tiles has changed?
You should use js version 3.0 to make your code worked instead of 3.1
Does this work for you?

OpenLayers, when specifying a style for layer, firefox doesnt render

When I specify the style attribute to the vector layer, firefox does not render the vectors on that layer.
To test this, just execute the included javascript and html page.
You'll see an EditingToolbar on the top right corner, try to draw a LineString with it using firefox.
What you'll discover is that the LineStrings do not appear on the layer at all.
Try to remove the styleMap attribute from the vectors layer and everything will work correctly.
If you know the reason for this problem, please let me know.
Thank you for your time and help in advance.
P.S
Also, you'll have to use your own OpenLayers library and link up to it from the html page.
Personally I'm using the latest version from GitHub because the other versions have another annoying bug:
There's a dialogue from google maps poping up constantly.

How to disable places on google map V3?

I'm trying to migrate my application to latest version of Google map API and found that Google appends it's own items by default from Google Places directory to the map.
It does not look right together with my own records as it creates duplicate items on the map which can be placed in correctly.
Is there an option how to hide this local businesses or to control what is shown and what is not?
here is sample code:

As you can see on map, there are few tiny icons, which you can click on and information would appear in bubble. I need to hide this icons or at least disable on click event for this items.
Just a pointer - this seems possible with custom styled maps. If I'm not mistaken, the feature type you're looking for would be poi.business, whose visiblity you would turn off.
There's a wizard to help you build the options array.
You can remove it by adding the following code:
var styles = [
{
featureType: "poi",
stylers: [
{ visibility: "off" }
]
}
];
var styledMap = new google.maps.StyledMapType(styles,{name: "Styled Map"});
