有人可以向我确认这可以用作某些变焦级别的无图块的标识符。如果我发出以下请求：“ http：//ecn.t2.tiles.virtualearth.net/tiles/a0030300.jpeg？ = not tile“
这可以作为空图块（图像宽度摄像头）的标识符？
我也想知道是否有一个呼叫呼叫rest api可以使用tilepositionx和tilepositiony而不是lat，lon为此请求：
Can someone confirm to me that this can be used as an identifier for no tiles at certain zoom levels. If I issue the following request: "http://ecn.t2.tiles.virtualearth.net/tiles/a0030300.jpeg?g=12276" in the response headers there is going to be entry "X-VE-Tile-Info=no-tile"
This can be taken as an identifier for the empty tile (image width camera)?
Also I wonder if there is a call to REST API that will use tilePositionX and tilePositionY instead lat, lon for this request: https://dev.virtualearth.net/REST/V1/Imagery/Metadata/Aerial/40.714550167322159,-74.007124900817871?o=xml&zl=20&key={BINGAPI_KEY}

相反，该标头可以用于识别该图块是否不可用。
图像元数据服务仅与纬度/经度坐标一起使用，而不是瓷砖坐标。检查特定图块坐标是否可用图像的唯一方法是请求图像可以检查标头（基本上是REST服务）。
Corrent, that header can be used to identify if imagery is not available for that tile.
The imagery metadata service only works with latitude/longitude coordinates and not tile coordinates. The only way to check if imagery is available for a specific tile coordinate is to request the image can check the header (basically a rest service).
