GOG 385 - LAB #5
(revised
06/01)
Instructions:
Use Grid A (Be sure you are
using Grid A and NOT Grid B)
Align the grid along the upper right-hand corner
of the photo placing the top and side of the grid along the edge of the
photograph itself. Read the grid by
lines, i.e., the first line is 1, the next 2, etc. In the exercises the first number refers to the lines going
across the grid, the second number refers to those going down. For example if the coordinates were 12/4 you
would go across 12 lines and then down 4 to find the designated cell.
To
be sure you have aligned the grid correctly, study the questions for each
image. If the question asks you to
identify the “round white objects at 12/23 and your grid alignment has no such
object at 12/23 or anywhere near, then you should change your grid orientation
until you do. Each image has some key
questions you can use as a guide in grid alignment.
Further explanation of the grid will
be provided in class.
Indicate
each corner of the image using latitude-longitude coordinates; upper-right,
lower-right, upper-left, lower-left.
