Question

我这里有tif文件，要切成瓦片缓存，三个比例尺1128.497176，564.248588，282.124294，对应的级别为19,20,21，但是现在发出的wmts服务对应的，0：1128.497176，1：564.248588，2：282.124294。在js端请求瓦片时，对应的层是19，20，21，我需要将0转成19，1转成20,2转成21，现在想通过wmts接口配置实现这个功能。新建了一个wmts101接口，想请帮配置一下，目前代码如下：

    <interface class="com.supermap.services.wmts.WMTSServlet" name="wmts101">
      <config class="com.supermap.services.wmts.WMTSConfig">
        <identification>
          <keywords/>
        </identification>  
        <provider>
          <serviceContact/>
        </provider>  
        <tileMatrixSets>
          <com.supermap.services.wmts.TileMatrixSet>
            <wellKnownScaleSet>Custom</wellKnownScaleSet>  
            <scales>1128.497176,564.248588,282.124294</scales>  
            <dpi>90.7142857142857</dpi>  
            <tileWidth>256</tileWidth>  
            <tileHeight>256</tileHeight>
          </com.supermap.services.wmts.TileMatrixSet>           
        </tileMatrixSets>  
        <customEntireBounds>-2.0037508342789244E7,-2.0037508342789244E7,2.0037508342789244E7,2.0037508342789244E7</customEntireBounds>
        <verifyMode>DEFAULT</verifyMode>
      </config>
    </interface>

就不问具体为什么这么做了，iServer发布WMTS瓦片矩阵集的瓦片矩阵标识是从0开始的，要么在前面加比例尺（直接在iDesktop生成地图缓存那儿导出缓存配置文件.sci，替换UGC5.0的sci，或者手动向sci文件中相关地方添加比例尺，其它类型缓存用对应数据库工具改metadata表即可），要么叠加的时候判断缩放级别再切换地图。
改WMTS接口配置也可以，iServer类参考： TileMatrixSet、 TileMatrix。

即再设置 TileMatrixSet的matrixList属性（也可能是tileMatrixs属性，建议使用类的全名），比如：

<com.supermap.services.wmts.TileMatrixSet>
    <wellKnownScaleSet>Custom</wellKnownScaleSet>  
    <scales>1128.497176,564.248588,282.124294</scales>  
    <dpi>90.7142857142857</dpi>  
    <tileWidth>256</tileWidth>  
    <tileHeight>256</tileHeight>
    <matrixList>
        <com.supermap.services.wmts.TileMatrix>
            <identifier>19</identifier>
        </com.supermap.services.wmts.TileMatrix>
        <com.supermap.services.wmts.TileMatrix>
            <identifier>20</identifier>
        </com.supermap.services.wmts.TileMatrix>
        <com.supermap.services.wmts.TileMatrix>
            <identifier>21</identifier>
        </com.supermap.services.wmts.TileMatrix>
    </matrixList>
</com.supermap.services.wmts.TileMatrixSet> 

TileMatrix其他参数是否必填请自行尝试。

已实现，谢谢毛工。
