Creating an MLClassify Function raster dataset
Do the following steps to create an MLClassify Function raster dataset:
- Create the MLClassify Function object.
- Create the MLClassify Function Arguments object.
- Set the properties for the function arguments.
- Specify the input raster.
- Specify the input signature file.
- Create a Raster Function object.
- Create a Function Raster dataset object.
- Initialize the new Function raster dataset with the raster function and its arguments.
The following code example shows how to create an MLClassify Function raster dataset by classifying a multiband raster using a signature file.
[C#]
//Define MLClassifyFunction and Arguments objects.
MLClassifyFunction mlClassify = new MLClassifyFunctionClass();
IMLClassifyFunctionArguments mlClassifyArgs = new MLClassifyFunctionArgumentsClass()
as IMLClassifyFunctionArguments;
//Open a raster dataset and the specify input raster and signature file.
mlClassifyArgs.Raster = inRasterDataset01;
string sSigPathName = "c:\\data\\tm321.gsg";
mlClassifyArgs.SignatureFile = sSigPathName;
//Define and initialize a Function raster dataset using the MLClassify function.
IFunctionRasterDataset mlDataset = new FunctionRasterDataset();
mlDataset.Init(mlClassify, mlClassifyArgs);
[VB.NET]
'Define MLClassifyFunction and Arguments objects.
Dim mlClassify As MLClassifyFunction
Dim mlClassifyArgs As IMLClassifyFunctionArguments
mlClassify = New MLClassifyFunction
mlClassifyArgs = New MLClassifyFunctionArguments
'Open a raster dataset and specify the input raster and signature file.
mlClassifyArgs.Raster = inRasterDataset01
Dim sSigPathName As String
sSigPathName = "c:\data\tm321.gsg"
mlClassifyArgs.SignatureFile = sSigPathName
'Define and initialize a Function raster dataset using the MLClassify function.
Dim mlDataset As IFunctionRasterDataset
mlDataset = New FunctionRasterDataset
mlDataset.Init(mlClassify, mlClassifyArgs)
