Method: projects.maps.create
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
创建一个 ID，用于渲染显示计算结果的地图图块。生成的 ID 应作为 GetTile 请求的一部分使用。
此属性与 GetTile 结合使用。调用 maps.create 会提供一个表达式和一些输出选项。maps.create 的结果是一个地图 ID，表示的是评估该表达式并应用这些选项后得到的图片。随后，可以调用 GetTile 来获取生成图片的任意位置和缩放级别下的某个图块的图片数据。地图 ID 的有效期为中等时间（几个小时）。
这对端点最常见的用例是使用某些计算输出的可视化结果填充地图视口。为此，计算输出必须满足对请求的图片格式的一些合理要求。具体而言，JPEG 或 PNG 格式要求有 1 个或 3 个输出波段，并且剪裁值超出 0-255 范围。

The resulting ID should be used as part of `GetTile` requests.\n\nThis is used in conjunction with `GetTile`. A call to `maps.create` provides an expression and some output options. The result of `maps.create` is a map ID that represents an image that is the result of evaluating that expression and applying those options. Subsequently, calls to `GetTile` can be made to get image data for a tile of the resulting image, at any desired location and zoom. The map ID will be valid for a moderate period (a few hours).\n\nThe most common use case for this pair of endpoints is to populate a map viewport with a visualization of the output of some computation. In order for that to be possible, the computation output has to meet some reasonable requirements for the requested image format.
