I have following paragraph and trying to understand what it clearly mention.
This paper shows several extensions and discusses the topology approach, while recognizing that reconstruction of height jumps is a challenge (A, 2010; B, 2007) and describing problems related to intersection lines and jump edges between two segments.
first sentence is clear to me. I have problem with while part. It contains that also. So, I am confused. I want to know this and describing.. is related to that or while.
If I simplify my question,
Does the stricture of second part is
- while recognizing (X) and describing (Y) or..
- while recognizing that (P and describing Q).
UPDATE: If I like to modify 1, Would it be possible to use one recognition as while recognizing (X) and (Y). I think yes, But Y is too long, Does this misguide the reader?
Can anyone help me to get the idea of this. thanks
