"열람" usually means something more than reading. We use "열람" for a specific reading.
For example, if you just read a book in your home, we don't use "열람" for that. If you read a newspaper, we don't use "열람" for that.
However, if you go to a library or a government office building, find a list of the official price history of a land in the place, and take a look at the data, we use "열람" for that.
"열람" in "공시가격 열람" could mean "review". It doesn't matter whether it is for deciding whether the price is optimal, correct, wrong, etc. The activity itself is "열람".
