使用ArcGis驱动访问arcgisonline数据的问题！

xiaol_deng

当我用arcgis驱动访问arcgisonline.com上的数据时成功加载了地球！我的earth文件如下：
<map name="ArcGIS Online" type="geocentric" version="2">
        
    <image name="arcgis-world-imagery" driver="arcgis">
        <url>http://services.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer</url>
                <nodata_image>http://services.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/100/0/0.jpeg</nodata_image>
    </image>
      
    <image name="arcgis-transportation" driver="arcgis">
        <url>http://services.arcgisonline.com/ArcGIS/rest/services/Reference/World_Transportation/MapServer</url>
    </image>
   
    <image name="arcgis-reference-overlay" driver="arcgis">
        <url>http://services.arcgisonline.com/ArcGIS/rest/services/Reference/World_Boundaries_and_Places_Alternate/MapServer</url>
    </image>
   
    <options>
        <lighting>false</lighting>
        <terrain>
            <min_tile_range_factor>9</min_tile_range_factor>
        </terrain>
    </options>
</map>
效果图如下：



但是当我想访问arcgisonline china首页的在线服务时却出现了错误！我的earth文件如下：
<map name="ArcGIS Online" type="geocentric" version="2">
        
   
      
    <image name="arcgis-transportation" driver="arcgis">
        <url>http://www.arcgisonline.cn/ArcGIS/rest/services/ChinaOnlineCommunity/MapServer</url>
    </image>
   
   
    <options>
        <lighting>false</lighting>
        <terrain>
            <min_tile_range_factor>9</min_tile_range_factor>
        </terrain>
    </options>
</map>
结果图如下：

看你怪可怜的，问题估计出现在数据，如下tile的format格式，oe估计没有mied的相关驱动。
chinaonline的tile信息：
  "tileInfo" : {
    "rows" : 256,
    "cols" : 256,
    "dpi" : 96,
    "format" : "Mixed",
    "compressionQuality" : 90,
    "origin" : {
      "x" : -20037508.342787,
      "y" : 20037508.342787
    },
worldimage的tile 的信息如下：
"tileInfo" : {
    "rows" : 256,
    "cols" : 256,
    "dpi" : 96,
    "format" : "JPEG",
    "compressionQuality" : 75,
    "origin" : {
      "x" : -20037508.342787,
      "y" : 20037508.342787
    },

Mixed—A Mixed cache uses JPEG in the center of the cache with PNG 32 on the edge of the cache. Use the mixed mode when you want to cleanly overlay raster caches on other layers.
