#54 looks a little too much like a cross hairs for a weapon so if there is a way to angle and make more map like and more engaging I would appreciate the effort
#56 is angled a little too far and may give us a difficult time as we use the mark alone in some places.
Also, could you try some of your work with the mark on top of the name. I typically like to use my logos both ways depending on the use.
Also, I discussed the concept of #46, #47, #49. #50 and #53 - The concept is dead - not enough of a tie to the geospatial space
