Image Segmentation to Shapefile of classes in ERDAS

Hello

 

I am using spatial modeler to create segments and then converts them into a category or class shapefile, after that I want to merge specific segments based on class value

 

when I did that, shapefile contains ten attributes but none of them is related with the class

 

I think there are two options:

 

  • Use segments as samples training to do a supervised classification (select segments at ramdon and give them a specific class)
  • Limit number of classes in the image segmentation (e.g only 30 classes)

 

 

Is there any way to do that and automatically?

 

 

 

the idea is that in the end only the shapefile is revised and edited with the classes

 

 

 

Thanks so much!!

Hope this helps.
