1. measuring on an orthophoto, you find that the width of a five-lane freeway is 0.2 inches. assuming that each lane in the freeway is 12 feet on the ground, what do you estimate the representative fraction of the photo to be? show your work.

The representative fraction of photo will be 1:3600

Explanation:

Orthophoto is constructed geometrically where there is no distortion unlike maps.

The width of a five lane freeway is 0.2 inches.

Assuming the width of each lane to be 12 feet, then the total width of all the five lanes is 12×5=60 feet

We know that 1 feet = 12 inches

So, 60 feet = 60×12= 720 inches

So , we get that 0.2 inches on the orthophoto is 720 inches on the ground.

So, 1 inch on the orthophoto = inches on the ground = 3600 inches.

Thus the scale is 1:3600

italy:

classic, nostalgic, romantic and beautiful. no place better than italy or sicily.
