I’m currently working on change detection using SAR dataset in ERDAS. I’m using radar tool; Blue is New Layer to generate the output of the change detection.
My question is how to input multiple data or to run a batch processing? Or is it only applicable to input just one dataset/mosaic image? Is there any other methods of the change detection that allow us to run a batch processing?
Thanks in advance.

Hiya. The Blue is New function uses a Spatial Model that can be found, along with a bunch of other models that come with IMAIGNE, here:
C:\Program Files\Hexagon\ERDAS IMAGINE 2020\etc\models
Just load that up in the Spatial Model Editor and you will be able to use batch from there.
I've just had a look at the model and it could probably do with a tidy up of the input ports - rearranging and dropping some where you may not want to change the variable.

Thanks for your reply. I’m also take a look on spatial modeler to run the process Blue is New Layer but my priority of work needs me to use the Erdas Imagine tools first.
I’m really appreciated with your answer. Thank you so much.

Thanks for your solutions. Currently I’m also study on the process of change detection using E-Z Coherence Change but the problem is I couldn’t find how to run the process by batch.
I’ll go through on the notes you attached. Thanks a lot.

"I’m also take a look on spatial modeler to run the process Blue is New Layer but my priority of work needs me to use the Erdas Imagine tools first. "
The Spatial Modeler is an ERDAS IMAGINE tool. The Spatial Model Editor is provided as a standard component of IMAGINE Professional. And when you display SAR data using the Blue is New option it is running Spatial Modeler (specifically wth the Model Johnnie references). So currently the best way to Batch the Blue is New function is via the Spatial Model Editor. If you do go down that route please do not directly edit the model in the etc directory. Make a copy first.

I have a problem on conducting Blue is New method on change detection using Desktop. My questions are:
1. Why the result of using Blue is New with Erdas Imagine 2016 and 2020 have a big different?
2. Why I cannot use the spatial modeler of Blue is New that have in Erdas Imagine Desktop?
Thanks in advance.
