Esri Leaflet

ImageMapLayer MosaicRule

Display an Image Service from ArcGIS Online or ArcGIS Server and apply a mosaic rule to dynamically control how the service combines rasters into a mosaic. This sample shows world temperature using the 8th raster only (August of 1950). More information about Image Services can be found in the L.esri.ImageMapLayer documentation.
