Property Overview

Property Details

attributeTable FeatureSet

The raster attribute table associated with an imagery layer. It returns categorical mapping of pixel values such as class, group, or category, or membership.

• Sample - Raster attribute table

• Raster Attribute Table

Example:

layer.when(function() {
  // accesses the raster attribute table of the layer
  var rasterAttributes = layer.serviceRasterInfo.attributeTable.features;
});

bandCount Number

Raster band count.

colormap Number[][]

Raster colormap that can be used to display the imagery layer. Each element in the array defines the pixel value and the red, green, and blue color values.

• Raster colormap

dataType String

Raster data type controls how the data is rendered by default.

Value	Description
generic	Uses the application defaults for resampling and stretching.
elevation	Applies bilinear resampling and a Min-Max stretch.
thematic	Applies nearest neighbor resampling and a Deviation stretch.
processed	No stretch is applied.
scientific	Uses the blue to red color ramp to display the data.
vector-uv	Uses the U (magnitude component) and V(direction component) components in the vector field renderer.
vector-magdir	Uses the magnitude and direction in the vector field renderer.

Possible Values:"generic"|"elevation"|"thematic"|"processed"|"scientific"|"vector-uv"|"vector-magdir"

extent Extent

The minimum and maximum X and Y coordinates of a bounding box containing all the raster data.

histograms Object[]

Raster histograms return basic name-value pairs for number of bins, min and max bounding values, counts of pixels in each bin.

See also:

• Raster histograms

keyProperties Object

Raster key properties.

multidimensionalInfo Object

The multidimensional information associated with the raster.

If defined, multidimensional information contains various "dimensions" of data for a particular value, such as time, depth, altitude, etc. Defining slices of particular dimensions in the layer is handled with the multidimensionalDefinition property of the mosaicRule.

pixelSize Point

Raster pixel size. Specifies the pixel size being identified on the x and y axis. Defaults to the base resolution of the dataset when not specified.

pixelType String

Pixel type for the raster data source.

Value	Range of values that each cell can contain
unknown	Pixel type is unknown
s8	-128 to 127
s16	-32768 to 32767
s32	-2147483648 to 2147483647
u8	0 to 255
u16	0 to 65535
u32	0 to 4294967295
f32	-3.402823466e+38 to 3.402823466e+38
f64	0 to 18446744073709551616

Possible Values:"unknown"|"s8"|"s16"|"s32"|"u8"|"u16"|"u32"|"f32"|"f64"

spatialReference SpatialReference

The spatial reference of the raster.

statistics Object[]

Raster band statistics. These include the minimum value in the raster, maximum value, mean of all values, and standard deviation.

Properties:

min Number The minimum pixel value.

max Number The maximum pixel value.

stddev Number The standard deviation of calculated pixel values.

avg Number The average of calculated pixel values.

Method Overview

Method Details

fromJSON(json){*}static

Creates a new instance of this class and initializes it with values from a JSON object generated from a product in the ArcGIS platform. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameter:

json Object A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns:

Type	Description
*	Returns a new instance of this class.

toJSON(){Object}

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() topic in the Guide for more information.

Returns:

Type	Description
Object	The ArcGIS portal JSON representation of an instance of this class.
