Just one caveat to Richard's note: It's reasonable to use aerial
photographs as a positional reference for your personal knowledge of
an area. For example, I was just in the Catskills and noted several
things without recording them on my GPS. I can use the aerial photo to
locate the feature I remember even if it's not on the photo because
it's too new or vice-versa in the photo but not on the ground because
it's been dismantled.
