本文提供了一个关于地图控件的应用实例，包括如何添加和移除全屏、版权、鹰眼、比例尺等功能，并展示了如何通过代码实现地图的放大、缩小、设置中心点及层级等操作。

地图鹰眼，比例尺，地图缩放控件应用，地图放大、缩小、设置中心点，设置瓦片显示层级等。功能没什么好说的，直接上图：

　　地图基本控制：

代码：

    <title>地图控制示例</title>
    <link rel="stylesheet" href="plugin/ol3/css/ol.css" type="text/css" />
    <style type="text/css">
        body, #mainMap {
            border: 0px;
            margin: 0px;
            padding: 0px;
            width: 100%;
            height: 100%;
            font-size: 13px;
        }
    </style>
    <script type="text/javascript" src="plugin/ol3/build/ol-debug.js"></script>

    <input type="text" id="txtCentX" />
    <label>纬度：</label>

    <input type="text" id="txtZoom" />
    <input type="button" value="设置" onclick="OpenlayerSetZoom(txtZoom.value);" />

    <div id="div_gis">

    </div>

</body>
</html>
<script type="text/javascript">
    LoadTiandituTileMap(0, 'div_gis', 1, 11, 8, 103.964571, 30.245677);
