Orthographic test IDS Tower

The IDS Tower is the tallest building in Minneapolis. Can we use angle measurements and the orthographic view to measure the height?

Photo 1: at the south east base of the tower held 5 feet high. 44.975623, -93.272140.

Walking 1 block east to 44.974760, -93.270526. Distance: 522.9 ft

Angle measurement photos:

vert_angle_deg=55.6 / horiz_angle_deg=-3.9
vert_angle_deg=-0.3 / horiz_angle_deg=-0.0
  • Angle Measurements:
    • Angle to top: 55.6°
    • Angle to bottom: -0.3°
    • Difference: 56.5°

Walking 2 blocks east to 44.974220, -93.269188. Distance: 919.4 ft

Angle measurement photos:

vert_angle_deg=39.8 / horiz_angle_deg=-1.0
vert_angle_deg=-1.2 / horiz_angle_deg=-0.3
  • Angle Measurements:
    • Angle to Top: 39.8°
    • Angle to Bottom: -1.2°
    • Difference: 41.0°
