Interface IRasterModel

All Superinterfaces:

Serializable

All Known Implementing Classes:

RasterModel

public interface IRasterModel
extends Serializable

Provides access to members that control the Raster Model.

Remarks

The RasterModel object is used to perform raster analysis using map algebra expressions and may include non-raster input/output formats (feature data, tables, etc). It also allows multiple lines of Map Algebra syntax to be used.

Steps to run a process using iRastermodel interface are as follows

1. Declare rastermodel object
2. Define the inputs into the expression using the "Bind..." methods
3. Create a map algebra expression string using the Script property
4. Execute the expression
5. Specify the output from the expression to an object using the "Bound..." property
6. Release the reference to the input/output data using the UnbindSymbol method
   

• Read the Working with ArcGIS Spatial Analyst objects technical document for general information on implementing Spatial Analyst operations.
