SFWMD Upgrading from NGVD 29 to NAVD 88 - Vertical Datum Upgrade |
|
To enhance the accuracy of our data, the SFWMD is upgrading the reference system used to measure water elevations in our monitoring network. In the coming months, SFWMD will shift from reporting water elevations in the National Geodetic Vertical Datum of 1929 (NGVD 29) to the North American Vertical Datum of 1988 (NAVD 88). This includes data within the SFWMD?s environmental database for hydrologic, meteorologic, hydrogeologic and water quality data. The upgrade will provide the public and stakeholders more accurate information about levels for waterbodies in our region. |

When NAVD 88 is fully implemented in 2024, water measurements will be published exclusively in NAVD 88. |
