Name Type Description
preemptive boolean | undefined experimental

If true the TileUTFGrid source loads the tiles based on their "visibility". This improves the speed of response, but increases traffic. Note that if set to false, you need to pass true as opt_request to the forDataAtCoordinateAndResolution method otherwise no data will ever be loaded. Default is true.
