Create a training sample dataset from existing points

Hi all,

 

I have run through the tutorial on performing image classification from both an object-oriented approach and a pixel-based approach. However, one of the things that is unclear to me is if it is possible to create a training sample dataset from a point or polygon file. For example many of us have binary data (e.g. presence(1), absence(0)) that we could use to create the training samples. Is it possible to do this? All of the methods I have seen start with an existing schema (bonus points if you can tell me how these are created). For example, here:

 

Creating training samples—ArcGIS Help | ArcGIS for Desktop 

and here:

Managing training samples—ArcGIS Help | ArcGIS for Desktop 

 

Does anyone know how I would create from scratch?
