Vs. 取り上げる.  Seems you can 取り上げる almost anything you can 拾い上げる (physical or otherwise), but the sense may be different.

(selecting examples from a dictionary to discuss in an article on acceptance of the word ギガ)
「ギガ」が接頭語にとどまらず、名詞として使われる例を拾い上げています。

Had a Japanese native correct an unrelated attempt at "pick up my dog" in an otherwise kanji-filled document.  Used this orthography （拾いあげる). あげる often gets this treatment.

I think this is straightforward [vt].  

sankoku gives two distinct, plainly defined senses for what daijs crams into a single sense (corresponding to the split I've made here). (If interested, daijs has a completely separate 2nd sense which could be a 3rd sense here). 

This split into two senses essentially corresponds to senses [1] and [2] of 取り上げる. In fact, sankoku definition for [2] is:
特に選んで取り上げる (問題点をー)

I'm not sure I've found the best (e.g.) for [2], but it doesn't seem to match all the English senses.  I don't think you can go to the car dealership and 拾い上げる the car you like, for example.  You are selecting something from a set of available information in order to further elaborate on it/deal with it/use it in some way(in order to 取り上げる[2] it)
