ArcGIS Help 10.1 - Create Mosaic Dataset (Data Management)

Summary

Makes an empty mosaic dataset in a geodatabase.

Usage

The destination geodatabase can be file, personal, or ArcSDE.
Once the mosaic dataset is created, you can use the Add Rasters to Mosaic Dataset to populate it with rasters.
The name of the mosaic dataset must keep within the limits of the geodatabase or underlying database. For example, the name cannot start with a number.

Syntax

CreateMosaicDataset_management (in_workspace, in_mosaicdataset_name, coordinate_system, {num_bands}, {pixel_type}, {product_definition}, {product_band_definitions})

Parameter	Explanation	Data Type
in_workspace	The path and name of a geodatabase.	Workspace
in_mosaicdataset_name	The name of the mosaic dataset.	String
coordinate_system	The coordinate system for the mosaic dataset, which will be used for all the associated files or features created.	Spatial Reference
num_bands (Optional)	The number of raster dataset bands supported by the mosaic dataset.	Long
pixel_type (Optional)	The bit depth of a cell, used to determine the range of values that the mosaic dataset output. For example, an 8-bit mosaic dataset can have 256 unique pixel values, which range from 0 to 255. If it is not defined, it will be taken from the first raster dataset. 1_BIT —A 1-bit unsigned integer. The values can be 0 or 1. 2_BIT —A 2-bit unsigned integer. The values supported can be from 0 to 3. 4_BIT —A 4-bit unsigned integer. The values supported can be from 0 to 15. 8_BIT_UNSIGNED —An unsigned 8-bit data type. The values supported can be from 0 to 255. 8_BIT_SIGNED —A signed 8-bit data type. The values supported can be from -128 to 127. 16_BIT_UNSIGNED —A 16-bit unsigned data type. The values can range from 0 to 65,535. 16_BIT_SIGNED —A 16-bit signed data type. The values can range from -32,768 to 32,767. 32_BIT_UNSIGNED —A 32-bit unsigned data type. The values can range from 0 to 4,294,967,295. 32_BIT_SIGNED —A 32-bit signed data type. The values can range from -2,147,483,648 to 2,147,483,647. 32_BIT_FLOAT —A 32-bit data type supporting decimals. 64_BIT —A 64-bit data type supporting decimals.	String
product_definition (Optional)	A template defining the number of bands and mid-wavelength ranges for each band. None —No band ordering is specified for the mosaic dataset. This is the default. NATURAL_COLOR_RGB —Creates a three-band mosaic dataset, with red, green, and blue wavelength ranges. This is designed for natural color imagery. NATURAL_COLOR_RGBI —Creates a four-band mosaic dataset, with red, green, blue and near infrared wavelength ranges. FALSE_COLOR_IRG —Creates a three-band mosaic dataset, with near infrared, red, and green wavelength ranges. FORMOSAT-2_4BANDS —Creates a four-band mosaic dataset using the FORMOSAT-2 wavelength ranges. GEOEYE-1_4BANDS —Creates a four-band mosaic dataset using the GeoEye-1 wavelength ranges. IKONOS_4BANDS) —Creates a four-band mosaic dataset using the IKONOS wavelength ranges. KOMPSAT-2_4BANDS —Creates a four-band mosaic dataset using the KOMPSAT-2 wavelength ranges. LANDSAT_6BANDS —Creates a six-band mosaic dataset using the Landsat 5 and 7 wavelength ranges from the TM and ETM+ sensors. LANDSAT_MSS_4BANDS —Creates a four-band mosaic dataset using the Landsat wavelength ranges from the MSS sensor. QUICKBIRD_4BANDS —Creates a four-band mosaic dataset using the QuickBird wavelength ranges. RAPIDEYE_5BANDS —Creates a five-band mosaic dataset using the RapidEye wavelength ranges. SPOT-5_4BANDS —Creates a four-band mosaic dataset using the SPOT 5 wavelength ranges. WORLDVIEW-2_8BANDS —Creates an eight-band mosaic dataset using the WorldView-2 wavelength ranges. CUSTOM —Allows you to define the number of bands and the mid-wavelength ranges for each band.	String
product_band_definitions [Band Name {Wavelength Minimum} {Wavelength Maximum},...] (Optional)	The band and wavelength information for the product_definition can be edited. You can modify the wavelengths, change the band order, or you can add or remove bands when using the CUSTOM product definition.	Value Table
