# 1, 2 & 3 Rank: I like the "cross hair" idea inside the D. However, cross hairs actually are a bit different. They are comprised of a single line in the up and right direction (as shown) but a double line in the down and left direction, to be more accurate. Is that possible?
#5 & 6 Rank are interesting with the exception of the font. Something similar to #1 & #2 would be preferred. Dark blue would be the preferred color, as well.
Rating #1 & 2: The globe with lat & long works. Prefer the R to be facing forward. Can the ord SURVEYING be two tone with the line through the text as the divider?
Rating #5 & 6: Only the word SURVEYING under the globe is preferred. Good design.
Rank 1 & 2: If you could put a small plus (+) at the intersection of the cross hairs, not touching any of the current lines and being the same line weight as the other lines, I think you have a winner.
