Domed colonnade on the Tidal Basin honoring the third president
The Thomas Jefferson Memorial stands on the south bank of the Tidal Basin in Washington, D.C., honoring the principal author of the Declaration of Independence and the third President of the United States. Designed by John Russell Pope in a Neoclassical style inspired by the Pantheon in Rome, it is a circular, open-air colonnade of Ionic columns beneath a shallow dome. Inside stands a 19-foot bronze statue of Jefferson by Rudulph Evans, surrounded by passages from his writings carved into the walls. The memorial was dedicated in 1943, on the 200th anniversary of Jefferson's birth.
In summer 2018, CyArk documented the memorial's exterior with the National Park Service, using terrestrial photogrammetry and laser scanning. Because Washington's airspace is restricted, CyArk captured aerial photographs from the National Park Service's law enforcement helicopter instead of a drone. The baseline documentation supports site managers working to understand the growth of biofilm on the memorial's dome.
