5 days ago · The main difference between NGVD29 and NAVD88 is the reference point used for elevation measurements. NGVD29 is based on a network of benchmarks and uses mean sea level as its reference point. NAVD88, on the other hand, is based on a geopotential datum and uses the Earth’s gravity field as its reference point.

3 hours ago · For decades it has been the NGVD 29. Now, it’s moving to what is called the NAVD 88. “All that means is changing from one reference point to another reference point. The lake level is still the lake level," said Florida Oceanographic Society Executive Director Mark Perry. Perry added it's not as if a foot of the lake magically disappeared.

May 22, 2024 · All lake level values are shown in feet above sea level per NGVD29 datum. The US Army Corps of Engineers (USACOE), and NYSDEC typically currently use NGVD 29 datum. However, it is probably only a matter of time before the government agencies convert to using NAVD 88 datum, which for our area is about 0.51 ft. higher.
