The map is available as a javascript widget and can be included on any web page. Just follow three steps.

1. Include the required libraries

The Vici widget requires 3 libraries to run. These are Google Maps, jQuery and of course the Vici library. Include these libraries in your page by adding the following code between the <head>-tags of the page:

<script type="text/javascript" src=""></script>
<script type="text/javascript" src="//" ></script>
<script type="text/javascript" src=""></script>

2. Determine where the map should be shown

Reserve a place on the page for the map by adding a <div>-tag with the desired layout. Give this element an id, for example "map". Here is an example:

<div id="map" style="width:600px; height:400px"></div>

3. Activate the widget

Examples from sites that implemented the wiget

Activate the widget by putting the following code on the bottom of the page, just before the </body>-tag:

<script type="text/javascript">
var mapObj = new ViciWidget(document.getElementById('map'), {"zoom": 14});

Use the id of the element you want the map to be shown. In this example the map has an initial zoom of 14. You may also chose the initial lattitude or longitude. You can do this for example by replacing {"zoom": 14} with {"center": { "lat": 50.84, "lng": 5.69}, "zoom": 8}.

There are more options. In the next example, the widget will highlight the most interesting locations for the displayed area. It will show visible objects only, both archeological and touristic, but it provides the user with a menu that enables him to change what is shown.

<script type="text/javascript">
var mapObj = new ViciWidget(document.getElementById('map'), {
    "highlights": 2,
    "showPrefbox" : true,
    "preferences": {"visibility": "onlyVisible", "era": "RomanAndContemporary"}

Example implementations

Here are some example implementations:

The widget is being using by, Oud Houten, Parklaan Landschapsarchitecten and - Articles on ancient history (custom implementation). Please let me know when you have implemented the widget or have wishes for a next version.
