What time of day is a shadow the most accurate representation of an objects size?

When the angle of the sun above the horizon is 45 degrees, then an error in measuring its altitude leads to the smallest error in calculating an object's size by measuring the length of its shadow.
So, if you are located in a place where it's possible for the sun to appear 45 degrees above the horizon at any time of day, then that's the time of day when such a calculation is most accurate.
If you're located in a place where it's neverpossible for the sun to appear 45 degrees above the horizon at any time of day, then the best time would be the time when the sun is as high as possible in the sky. That's local solar Noon.

The most accurate way to show the Earth's continents and oceans is by using a map projection that preserves the relative size and shape of landmasses, such as the Winkel Tripel projection. This projection minimizes distortion of continents and oceans compared to other types of projections. Additionally, utilizing a globe is the most accurate representation of Earth's true shape and geography.
