Iterate Rasters—Help | ArcGIS for Desktop

Summary

Iterates over rasters in a Workspace or a Raster Catalog.

This tool is intended for use in ModelBuilder and not in Python scripting.
Rasters in a workspace or Raster Catalog can be restricted to iterate over raster types, such as ASC, BIL, BIP, BMP, BSQ, CIT, COT, DT0, DT1, DT2, ERS, GIF, GIS, GRID , HDF, IMG, JP2, JPG, LAN, LGG, NTF, OVR, PNG, RAW, RPF, SID, and TIF.
The tool has two outputs: Output Raster and Name, which could be used as in-line variable %Name% in other tools.
If an Iterator is added to a model, all tools in the model iterate for each value in the iterator. If you do not want to run each tool in the model for each iterated value, create a sub-model/model within a model/nested model that contains only the iterator and add it as a model tool into the main model.

IterateRasters_mb (in_workspace, {wildcard}, {raster_format}, {recursive})

Parameter	Explanation	Data Type
in_workspace	Workspace or a Raster Catalog containing the rasters to iterate through.	Workspace; Raster Catalog
wildcard (Optional)	Combination of * and characters that help to limit the results. The asterisk is the same as saying ALL. If no wildcard is specified, all inputs will be returned. For example, it can be used to restrict Iteration over input names starting with a certain character or word (e.g., A* or Ari* or Land*,and so on).	String
raster_format (Optional)	Choose the Raster Format, such as ASC, BIL, BIP, BMP, BSP, BSQ, CIT, COT, DT0, DT1, DT2, ERS, GIF, GIS, GRID, HDF, IMG, JP2, JPG, LAN, LGG, NTF, PNG, RAW, RPF, SID, and TIF, or type in other extensions.	String
recursive (Optional)	Determines if subfolders of the main folder will be iterated through recursively. Checked—Will iterate through all subfolders. Unchecked—Set as Default. Will not iterate through all subfolders.	Boolean

This tool does not use any geoprocessing environments
