Resample Library Spectra

inputLibrarySpectra

(Required)

An Esri spectral library or ENVI spectral library file with wavelength information.

The input can be the Portal ItemID.

Syntax: A JSON object describing the input library spectra.

Example

1
{"itemId": <portal item id>}

inputSpectra

(Required)

Esri Spectral Library item ID. The item can be published from a spectral library file containing spectral signatures, or from a point feature class created by the training sample manager in classification tools in ArcGIS Pro.

Syntax: JSON object describes the input spectra(s).

Example

1
2
{"itemId": <portal item id>}
{“url”: <feature service url>}

outputName

(Required)

The output Esri spectral library file with the resampled wavelength information.

Example

1

3
4

//item properties
{"name": "findtrees", "folderId": "nodsfiajoirejiojenoiwnioew", "itemProperties": {}}

//uri
{“uri”:<path>}

targetSensor

(Required)

Specifies the target spectra, or a custom spectra library file or image, that contains the target spectra.

• LANDSAT-9—The target spectra will be Landsat 9 satellite data with 7 bands.
• LANDSAT-8—The target spectra will be Landsat 8 satellite data with 7 bands.
• LANDSAT-7_NO_THERMAL—The target spectra will be Landsat 7 satellite data with 6 bands.
• LANDSAT-5_NO_THERMAL—The target spectra will be Landsat 5 satellite data with 6 bands.
• LANDSAT-4_NO_THERMAL—The target spectra will be Landsat 4 satellite data with 6 bands.
• SENTINEL-3—The target spectra will be Sentinel-3 satellite data with 21 bands.
• SENTINEL-2A—The target spectra will be Sentinel-2A satellite data with 13 bands.
• SENTINEL-2B—The target spectra will be Sentinel-2B satellite data with 13 bands.
• ASTER_BANDS_1_TO_9—The target spectra will be ASTER satellite data with 10 bands.
• CUSTOM_TARGET_IMAGE_OR_SPECTRA—A custom spectral library file or image that contains the target spectra will be used. This is the default.

customTargetImageOrSpectra

(Optional)

A custom spectral library file or image with wavelength information that contains the target spectra.

This parameter is active when the targetSensor parameter value is CUSTOM_TARGET_IMAGE_OR_SPECTRA.

Example:

1
2
3
{"itemId": <portal item id>}
{"url": <image service url>}
{"uri": <cloud raster uri or shared data path>}

customTargetImageOrSpectra

(Optional)

Specifies the resampling method that will be used for the output library spectra.

• BAND_AVERAGING—A simple average of the input spectra based on all band values that fall within each target band’s wavelength range will be used. This is the default.
• GAUSSIAN_CONVOLUTION—A Gaussian model will be used to represent the spectral response function of the sensor, and the input band values will be weighted for each wavelength range.

Syntax: string
