资源简介：
Millions of Americans watched as the Statue of Freedom was gently lifted from its perch atop the Capitol in Washington D.C. on Mother's Day, May 9, 1993. After 130 years, this great symbol of America was in desperate need of cleaning and repair. Identified in the National Geodetic Survey (NGS) data base as CAPITOL HEAD OF FREEDOM, she also represented a important part of the horizontal portion of the National Geodetic Reference System (NGRS).
