Taken from the Daijirin (Yahoo.co.jp):

［1］    どう考えてみても明らかに。非常に。
However you think about it, it's clearly... Extremely...
    ・    ―痛そうだ
    ・    ―高くて手が出ない

There's more than those, but I think that one sounds about right for that. 'Indeed' seems like a different meaning (to show agreement or affirmation with what someone has said, so that something is just as was predicted or common sense would suggest).

I think the best definition is "No matter how you look at it", which can be a synonym for both "clearly" and "indeed" i'd say.
