GPTool

public class BatchCalculateStatistics
extends AbstractGPTool

Runs the Calculate Statistics tool on multiple raster datasets. The Batch Calculate Statistics tool is contained in the Data Management Tools tool box.

Usage tips:

• Calculating allows ArcGIS applications to properly stretch and symbolize raster data for display.
• A skip factor controls the portion of the raster dataset that is used when calculating the statistics. The input value indicates the horizontal or vertical skip factor, where a value of 1 will use each pixel and a value of 2 will use every second pixel. The skip factor can only range from 1 to the number of columns/rows in the raster dataset.
• Calculating statistics on the GRID and the RADARSAT2 formats alway uses a skip factor of 1.
• The skip factors for raster datasets stored in a file geodatabase or an ArcSDE geodatabase are quite different. First, if the x and y skip factors are different, the smaller skip factor will be used for both the x and y skip factors. Second, the skip factor is related to the pyramid level that most closely fits the skip factor chosen. If the skip factor value is not equal to the number of pixels in a pyramid (for example, if the skip factor is 5 and the closest pyramid level is 4 x 4 pixels, which is level 2), the software will round down to the next pyramid level (in this case, 2) and use that value as the skip factor.
• A skip factor is not used for all raster formats. The raster formats that cannot use the skip factor include ADRG, CIB, and CADRG.
• The Ignore Values option allows you to exclude a specific value from the calculation of statistics. You may want to ignore a value if it is a NoData value or if it will skew your calculation.

Constructor Detail

BatchCalculateStatistics

public BatchCalculateStatistics()

Creates the Batch Calculate Statistics tool with defaults.

Initializes the array of tool parameters with the default values specified when the tool was created.

BatchCalculateStatistics

public BatchCalculateStatistics(Object inputRasterDatasets)

Creates the Batch Calculate Statistics tool with the required parameters.

Initializes the array of tool parameters with the values as specified for the required parameters and with the default values for the other parameters.

Parameters:

inputRasterDatasets - the input raster datasets.

Method Detail

getInputRasterDatasets

public Object getInputRasterDatasets()

Returns the Input Raster Datasets parameter of this tool . This parameter is the input raster datasets. This is a required parameter.

Returns:

the Input Raster Datasets

setInputRasterDatasets

public void setInputRasterDatasets(Object inputRasterDatasets)

Sets the Input Raster Datasets parameter of this tool . This parameter is the input raster datasets. This is a required parameter.

Parameters:

inputRasterDatasets - the input raster datasets.

getNumberOfColumnsToSkip

public int getNumberOfColumnsToSkip()

Returns the Number of columns to skip parameter of this tool . This parameter is the number of horizontal pixels between samples. the value must be greater than zero and less than or equal to the number of columns in the raster dataset. The default is 1 or the last skip factor used. the skip factors for raster datasets stored in a file geodatabase or an ArcSDE geodatabase are different. First, if the x and y skip factors are different, the smaller skip factor will be used for both the x and y skip factors. Second, the skip factor is related to the pyramid level that most closely fits the skip factor chosen. If the skip factor value is not equal to the number of pixels in a pyramid layer, the number is rounded down to the next pyramid level and those statistics are used. This is an optional parameter.

Returns:

the Number of columns to skip

setNumberOfColumnsToSkip

public void setNumberOfColumnsToSkip(int numberOfColumnsToSkip)

Sets the Number of columns to skip parameter of this tool . This parameter is the number of horizontal pixels between samples. the value must be greater than zero and less than or equal to the number of columns in the raster dataset. The default is 1 or the last skip factor used. the skip factors for raster datasets stored in a file geodatabase or an ArcSDE geodatabase are different. First, if the x and y skip factors are different, the smaller skip factor will be used for both the x and y skip factors. Second, the skip factor is related to the pyramid level that most closely fits the skip factor chosen. If the skip factor value is not equal to the number of pixels in a pyramid layer, the number is rounded down to the next pyramid level and those statistics are used. This is an optional parameter.

Parameters:
