Desktop Help 10.0 - 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})

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
