mosaicRule
The image service uses a mosaic rule to mosaick multiple rasters on the fly. The mosaic rule parameter is used by many image service operations, for example, export image and identify operations.

Properties
| Property | Details |
|---|---|
| ascending | Indicate whether to use ascending or descending order. |
| fids | A list that defines a subset of rasters used in the mosaic, be aware that the rasters may not be visible at all scales. |
| itemRenderingRule | The rendering rule applies on items before mosaicking. |
| lockRasterIds | Lock a few rasters in the image service. Used together with esriMosaicLockRaster. |
| mosaicMethod | A string value that determines how the selected rasters are ordered. Must be one of the following values: esriMosaicAttribute, esriMosaicCenter, esriMosaicLockRaster, esriMosaicNadir, esriMosaicNone, esriMosaicNorthwest, esriMosaicSeamline, esriMosaicViewpoint |
| mosaicOperation | Use the mosaic operation to resolve overlap pixel values: from first or last raster, use the min, max or mean of the pixel values, or blend them. If property is present, must be one of the following values: MT_BLEND, MT_FIRST, MT_LAST, MT_MAX, MT_MEAN, MT_MIN, MT_SUM |
| multidimensionalDefinition | Definition of multidimentional variables. |
| sortField | The field name used together with esriMosaicAttribute method. |
| sortValue | The base sort value used together with esriMosaicAttribute method and sortField parameter. |
| viewpoint | Use a view point along with esriMosaicViewpoint. |
| where | Deprecated. Use layerDefinition.definitionExpression instead. |
