Required

Description: Class descriptions are training site polygons and their class descriptions. The structure of the geometry is the same as the structure of the JSON geometry objects returned by the ArcGIS REST API.

Syntax:

{
  "classes":  [  // An array of classes
    {
      "id" : <id>,
      "name" : "<name>",
      "geometry" : <geometry> //polygon
    },
    {
      "id" : <id>,
      "name" : "<name>",
     "geometry" : <geometry>  //polygon
    }
    ...
    ]
}

Examples:

{
  "classes":  [  // An array of classes
    {
      "id" : 1,
      "name" : "class1",
      "geometry" : {"rings": [[[-13555360.4191,5911556.581],[-13489311.5669, 5898227.932],[-13423477.4153,5884426.3329],[-13602646.9571, 5717848.4135], 
[-13587119.9125, 5781976.6214],[-13571360.1713, 5846543.2654],[-13555360.4191, 5911556.581]]]}
    },
    {
      "id" : 2,
      "name" : "class2",
     "geometry" : {"rings": [[[-12555360.4191,5811556.581],[-12489311.5669, 5798227.932],[-12423477.4153,5784426.3329],[-12602646.9571, 5617848.4135], 
[-12587119.9125, 5681976.6214],[-12571360.1713, 5746543.2654],[-12555360.4191, 5811556.581]]]}
    }
    ...
    ]
}

Description: Specifies the mosaic rule when defining how individual images should be mosaicked. When a mosaic rule is not specified, the default mosaic rule of the image service will be used (as advertised in the root resource: defaultMosaicMethod, mosaicOperator, sortField, sortValue).

See the mosaic rule objects for the JSON syntax and examples.

Description: Specifies the rendering rule for how the requested image should be rendered.

See the raster function objects for the JSON syntax and examples.

Description: The pixel level being used (or the resolution being looked at). If pixel size is not specified, then pixelSize will default to the base resolution of the dataset.

The structure of the pixelSize parameter is the same as the structure of the point object returned by the ArcGIS REST API. In addition to the JSON structure, you can specify the pixel size with a comma-separated syntax.

Syntax:

• JSON structure: pixelSize={point}
• Point simple syntax: pixelSize=<x>,<y>

Examples:

• pixelSize={"x": 0.18, "y": 0.18}
• pixelSize=0.18,0.18
