Creates an ID that can be used to render map tiles showing the results of a computation. The resulting ID should be used as part ofGetTilerequests.
This is used in conjunction withGetTile. A call tomaps.createprovides an expression and some output options. The result ofmaps.createis a map ID that represents an image that is the result of evaluating that expression and applying those options. Subsequently, calls toGetTilecan 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).
The 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. In particular, JPEG or PNG format requires that there be one or three output bands, and clips values that are outside the 0-255 range.
