Description
An image service provides access to raster data through a web service. Multiple rasters can be served as one image service through mosaic dataset technology, dynamically processed and mosaicked on the fly. An image service supports accessing the mosaicked image, its catalog, and the individual rasters in the catalog.
An image service supports dynamic access and tiled access. Dynamic access provides more functionality, and tiled access provides faster and more scalable access to precooked tiles. There are two types of tiles: map tiles and elevation tiles. Map tiles (introduced at 10.1) represent rendered map images, typically in JPEG or PNG format. Elevation tiles (introduced at 10.3) represent elevation data and are stored as Limited Error Raster Compression (LERC) tiles.
The ArcGIS REST API Image
resource root information represents an image service published with ArcGIS Server. The resource provides basic information associated with the image service, such as the service description, its name, its extent, pixel sizes, and band counts.
Child operations
The Image
resource supports the following operations
- Add Rasters—Add new rasters to the image service.
- Compute Cache Info—Compute and generate new image tile cache schemes for the image service.
- Calculate Volume—Compute a volumetric calculation on the elevation data.
- Compute Class Statistics—Calculate sample classes’ pixel statistics of the image service for composing spectral signatures of defined classes
- Compute Histograms
