Can anyone guide me,

Hi Bik,

In the model builder we have inbuilt iteration functionality where we can call the rasters in the workspace.

Go through the link;

Hi,

Thanks, but I don't know how to add the formula.

Because for example formula is NIR -R

So, in raster calculator which NIR and R need to choose because it is many images?

I am so sorry if I am not understand. I still stuck in this.

Thanks,

Nik

Hi,

The band (as images specified by you) specification like bandwidth depends upon sensor. What is your data source? For example like landsat, liss,spot etc...

this might help you;

Hi,

my sensor is MCA 6 with 6 bands

So if in one folder which data will be chosen since the data in one group.

This is the example for one image, I am successfully did:

Inline image 1

But the problem now how to do the same using iterate Rasters?

Thanks,

Step one: Make a model

Step two: Search for "Raster Calculator" in the search window (usually on the left side of the ArcMap Window)

Step three: drag the tool into the model builder box

Step four: double-click the tool and input your equations

Bonus: Use the Iterate function to loop through multiple rasters
