The URL of the dataset's collection.json.
Optionaldate?: DateThe date and time of the data to retrieve. If omitted, it behaves as if the current date and time new Date() was specified.
Optionalband?: stringThe band of the dataset to use. If omitted, the first band included in the dataset (the first in the order defined in collection.json) is used.
Optionalresampling?: ResamplingThe resampling method to use. If omitted, it behaves as if nearest neighbor (je.Resampling.NEAREST) was specified.
OptionalcolorMapObject?: ColorMapObjectThe color map conditions for visualization. If omitted, it behaves as if {min: 0, max: 255, colors: ["000000", "ffffff"]} was specified.
For color images or classification-type data (data where photometricInterpretation == 1 is not true), this is ignored and the colors originally specified in each dataset take precedence.
To avoid issues when sending and receiving rendering conditions between threads such as web workers, this uses ColorMapObject rather than ColorMap.
OptionaltileSize?: numberThe size of the tile to create (the number of pixels in width and height). Operation has been verified with 256 and 512. If not specified, it behaves as if 256 was specified.
Optionaldelay?: numberTiles are retrieved in batches at this interval [milliseconds]. If not specified, it behaves as if 500 was specified. Increasing this value can make communication more efficient by aggregating multiple tile rendering instructions that arrive within this interval and retrieving the data in a batch, but it takes longer for the results to be returned.

Creates tile images using WMTS (Web Map Tile Service) style parameters. Use this when integrating with a map API, for example by using ImageTile from OpenLayers.
