Question regarding environment

[jlabhishek]

Hello, I have a few questions:

In the observation grid, category and itype fields are defined and for each object it has some values , but how do I get the information regarding what those integer values mean. Where is that mapping done in code.
Can we use these two values to exactly map the position of an option in render screen and in code, or some other information is necessary for that. I wish to know which parameter gives the object location for the object I am seeing on the game screen.

Thank you
