HTML map of the hospital, using Google maps. This has a custom overlay (background) which shows the roads internal to the hospital. Different types of parking is hightlighed and bus stops and entrances to the hospital are shown. A list of services can be clicked on which will highlight the building they are in and center the map on that location.



Clicking a building will show details:

Doing whatever:



'Ambulance house' and 'Helicopter house' may or may not be the offical names of the buildings.

Building co-ordinates are stored in this format in sepearte js files:
var buildings = [];
var ict = {
    title: "ICT Services",
    key: "itServices",
    titleCoordinates: { lat: -39.0747770079001, lng: 174.0569919347763 },
    description: "Applications, Business Intellignence, Reporting and Development",
    coordinates: [{
        lat: -39.07470621091739,
        lng: 174.05701607465744
    }, {
        lat: -39.07475202073784,
        lng: 174.0570965409279
    }, {
        lat: -39.074962329077316,
        lng: 174.05688732862473
    }, {
        lat: -39.07491027261602,
        lng: 174.0568122267723
    }]
}

buildings.push(ict);
etc - add more buildings as required

This mob of co-ordinates is just referenced in the HTML
    <script type="text/javascript" src="buildingPersistance.js"></script>
    <script type="text/javascript" src="otherPersistance.js"></script>

Ok.
You have to sign up with google api and get a map key. Cram the script tag in your html:

    <script src="https://maps.googleapis.com/maps/api/js?key=[your key here]"></script>

Hook up an initialisation method to run when the maps stuff is loaded

        google.maps.event.addDomListener(window, 'load', initMap);

You need an initialisation method

        function initMap() {
            var uluru = {
                lat: -39.072474,
                lng: 174.055992
            };
            map = new google.maps.Map(document.getElementById('map'), {
                center: uluru,
                zoom: 17,
                styles: [{
                    featureType: 'poi',
                    stylers: [{
                        visibility: 'off'
                    }]
                }, {
                    featureType: 'transit',
                    elementType: 'labels.icon',
                    stylers: [{
                        visibility: 'off'
                    }]
                }]
            });

            // draw any buildings we have
            drawBuildings(map, buildings);
etc ...

When creating the map object the center will set the start location of the map
Styles defines what objects you want to show on the map (a heap of stuff shows by default)

Draw the things you want

        function drawBuildings(map, buildings) {
            for (var i = 0; i < buildings.length; i++) {
                var building = buildings[i];
                var buildingCoords = [];
                for (var c = 0; c < building.coordinates.length; c++) {
                    var coordinate = building.coordinates[c];
                    buildingCoords.push(new google.maps.LatLng(coordinate.lat, coordinate.lng));
                }
                var strokeColor = building.strokeColor ? building.strokeColor : '#000';
                var fillColor = building.fillColor ? building.fillColor : '#000';
                var buildingDefinition = new google.maps.Polygon({
                    paths: buildingCoords,
                    draggable: false,
                    editable: false,
                    strokeColor: strokeColor,
                    strokeOpacity: 0.8,
                    strokeWeight: 2,
                    fillColor: fillColor,
                    fillOpacity: 0.35,
                    originalStrokeColor: strokeColor,
                    originalFillColor: fillColor,
                    key: building.key,
                    description: building.description,
                    title: building.title
                });
                buildingDefinition.setMap(map);


Adding a popup for a building

                // build the popup information if we have a description for this building
                if (buildingDefinition.description) {
                    buildingDefinition.addListener('click', function(event) {
                        var contentString = '<div class="info-list-title">' + this.title + "</div>" + this.description;
                        infowindow.setContent(contentString);
                        infowindow.setPosition(event.latLng);
                        infowindow.open(map);
                    });
                }

Creating a label for a building (using maplabel-compiled.js from ... somewhere?)

                // create a label for this building
                if (building.title && building.titleCoordinates) {
                    var mapLabel = new MapLabel({
                        text: building.title,
                        position: new google.maps.LatLng(building.titleCoordinates.lat, building.titleCoordinates.lng),
                        map: map,
                        fontSize: 9
                    });
                    mapLabels.push(mapLabel);
                }
