As Rachel said, a "birds eye view" can mean that you see the whole picture. It also used in art and photography to represent a literal "view from above." Likewise, a "worms eye view" is a "view from below," where the camera (or drawing perspective) is placed low to the ground facing up.

A bird's eye view means seeing something like how a bird would see it flying. You see the entire picture of what's going on, not just a portion or snapshot of it. I have never heard of a "worm's eye view."
