根据您的偏好保存内容并对其进行分类。
卫星图像图块是一种正射影像。它们是由卫星和机载相机拍摄的图像，可提供地球的俯视（天底或近天底）图像。
获取卫星图块
获得会话令牌后，您就可以开始发出卫星图块请求了。
由于会话令牌适用于整个会话，因此您无需在功能块请求中指定地图选项。
以下代码示例展示了卫星图块的典型会话令牌请求。
curl -X POST -d '{
"mapType": "satellite",
"language": "en-US",
"region": "US"
}' \
-H 'Content-Type: application/json' \
"https://tile.googleapis.com/v1/createSession?key=YOUR_API_KEY
您可以通过发出 HTTPS GET 请求来获取卫星图块，如以下示例所示。
curl "https://tile.googleapis.com/v1/2dtiles/z/x/y?session=YOUR_SESSION_TOKEN&key=YOUR_API_KEY"
图块请求示例
请看以下代码示例，该示例请求缩放级别为 15、x 和 y 坐标为 (6294, 13288) 的单个卫星图块。
curl "https://tile.googleapis.com/v1/2dtiles/15/6294/13288?session=YOUR_SESSION_TOKEN&key=YOUR_API_KEY" --output /tmp/example_tile.png
在此示例中，服务器没有响应消息。而是将图块下载到本地文件。

[Learn more](/maps/comms/eea/faq). In addition, certain content from the Map Tiles API will no longer be returned. [Learn more](/maps/comms/eea/map-tiles).\n\nSatellite image tiles are a form of orthophotography. They're\nimages captured by both satellite and airborne cameras, and they deliver\ntop-down (nadir or near-nadir) imagery of the earth.\n\nGetting satellite tiles\n-----------------------\n\nYou can begin making satellite tile requests after you get a session token.\nBecause the session token applies to the entire session, you don't have to\nspecify the map options with your tile requests.\n\nThe following code sample demonstrates a typical session token request for\nsatellite tiles. \n\n```json\ncurl -X POST -d '{\n \"mapType\": \"satellite\",\n \"language\": \"en-US\",\n \"region\": \"US\"\n}' \\\n-H 'Content-Type: application/json' \\\n\"https://tile.googleapis.com/v1/createSession?key=YOUR_API_KEY\n```\n\nYou get satellite tiles by making an HTTPS GET request, as shown in the\nfollowing example. \n\n```json\ncurl \"https://tile.googleapis.com/v1/2dtiles/\u003cvar class=\"apiparam\" translate=\"no\"\u003ez\u003c/var\u003e/\u003cvar class=\"apiparam\" translate=\"no\"\u003ex\u003c/var\u003e/\u003cvar class=\"apiparam\" translate=\"no\"\u003ey\u003c/var\u003e?session=\u003cvar class=\"apiparam\" translate=\"no\"\u003eYOUR_SESSION_TOKEN\u003c/var\u003e&key=YOUR_API_KEY\"\n```\n\nExample tile request\n--------------------\n\nConsider the following code example, that requests a single satellite tile at\nzoom level 15, with x and y coordinates of (6294, 13288). \n\n```json\ncurl \"https://tile.googleapis.com/v1/2dtiles/15/6294/13288?session=\u003cvar class=\"apiparam\" translate=\"no\"\u003eYOUR_SESSION_TOKEN\u003c/var\u003e&key=YOUR_API_KEY\" --output /tmp/example_tile.png\n```\n\nThere is no response message from the server in this example. Instead, the tile\njust downloads to a local file.\n\nFor information about response message headers, see\n[Pre-Fetching, Caching, or Storage of Content](/maps/documentation/tile/policies#pre-fetching,-caching,-or-storage-of-content)."]]
