Description:
Abstract:
This website contains a partial section of the Everglades Gage Gazetteer. Coastal stations funded by the Priority Ecosystem Science Program and the Pink Shrimp sites, funded by the Critical Ecosystem Studies Initiaitve and now discontinued, are included on the SOFIA web portal. For information on other stations, contact Mark Zucker.
Purpose:
In order to maintain a coastal network, it is important to account for the base datum of a station for the collection of water level and for the computation of discharge. Stations in Florida Bay and the southwest coast of Florida were surveyed to the North American Vertical Datum of 1988 by the National Mapping Division (NMD) in the mid to late 1990's. Resource managers and other academic institutions have requested elevation information for coastal stations and with the development of the EDEN network, elevation information collected by NMD is available on SOFIA.

The inital gage survey was funded by the NMD High Accuracy Elevation Data Collection project. These gage sites were collected informally by NMD personnel as part of the High Accuracy Elevation Data project in the mid to late 1990s, as requested by the scientists.  A very comprehensive set of gage sites, descriptions, and values was assembled.  Project personnel decided to make a gazetteer for the South Florida community. Therefore, it was not formally reviewed at that time but many scientists have been using it for years. The quality control process was very tight.  Sites were usually surveyed several different times.  Some gages were re-verified between 2000 and 2007 funded by the Priority Ecosystem Science program. Additionally, the data were processed using different techniques and software packages by several different people.

Data_Set_Credit:
The Gazetteer compilation contains the results of geodetic surveys at Everglade's water gage sites by personnel of the U. S. Geological Survey (USGS) Eastern Region Geography, formerly the National Mapping Division (NMD). These surveys were conducted under the auspices of the USGS Place-Based Studies Program (now Priority Ecosystems Science), and the Everglades National Park Critical Ecosystem Studies Initiative. The data also includes results from the 1997 Florida Bay Marine Monitoring Network Gage Survey, a cooperative effort between the USGS, the U.S. Army Corps of Engineers, and the National Park Service.

Data_Quality_Information:
Logical_Consistency_Report:
In most cases the gage recorder housing, or gage box, was used as the monument of the survey measurement. The Gazetteer couples positional and descriptive data with a photographic record of each site. A Google Map showing the location of the site is included for each site as well.
Completeness_Report:
Gages funded by the Greater Everglades Priority Ecosystems Science program and the Pink Shrimp sites are included on the SOFIA website.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal values in the latitude and longitude fields are shown only to hundredths of decimal seconds. This was done for a variety of reasons including: the difficulty of repeating the exact survey position especially with the AHF (helicopter based instrument), the gages are flat and level so there were several possible measurement locations for the box, and the scientists only wanted or needed the vertical accuracy. The horizontal data as they were obtained are more accurate than the vertical. However, the values shown on the gage site pages do not reflect this accuracy as it was not the intent of the project.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The survey data presented here were established with differential GPS techniques which provide three-dimensional (3D) measurements. The 3D position measured at each point is provided as latitude, longitude and ellipsoid height in the NAD 83 datum. The reported NAVD 88 elevation, in meters, is the National Geodetic Survey (NGS) GEOID99 modeled orthometric height.

Although all the sites were positioned with GPS, this compilation includes results of different GPS methods and survey procedures, yielding small but significant differences in vertical accuracy. One hundred-nine sites were positioned by static occupations, and thirty-six by the USGS Airborne Height Finder (AHF) System. The AHF surveys, with repeat observations at each site, provide heights within 4-5 cm of datum. A majority of the static surveys employed long duration observations, typically 48 hours, producing heights within 2 cm of datum. The 1997 Florida Bay Survey is estimated to be within 3-4 cm of datum, due to different procedures and the available reference control.

Beginning in 1998, both the AHF and the static gage surveys were tied to ground stations of the AHF Control Network, developed by USGS and referenced to NAD 83(97) via the NGS MIA3 Continuously Operating Reference Station (CORS).

Process_Description:
This excerpt of the Everglades Gage Gazetteer contains the results of geodetic surveys at Everglade's water gage sites by personnel of the U. S. Geological Survey (USGS) Eastern Region Geography, formerly the National Mapping Division (NMD). These surveys were conducted under the auspices of the USGS Place-Based Studies Program, and the Everglades National Park Critical Ecosystem Studies Initiative. The Gazetteer couples positional and descriptive data with a photographic record of each site.

In most cases the gage recorder housing, or gage box, was used as the monument of the survey measurement. Construction of permanent monuments was beyond the mission and manpower of the survey project. Nonetheless the gage box serves as a fairly stable and readily identifiable temporary monument. Gage operators are encouraged to transfer the height of the surveyed reference point from the gage box to permanent locations, especially before modifying the gage structure. In most cases benchmarks were installed by Florida coastal staff including outside staff gages.

The survey data presented here were established with differential GPS techniques which provide three-dimensional (3D) measurements. The 3D position measured at each point is provided as latitude, longitude and ellipsoid height in the NAD 83 datum. The reported NAVD 88 elevation, in meters, is the National Geodetic Survey (NGS) GEOID99 modeled orthometric height.

Although all the sites were positioned with GPS, this compilation includes results of different GPS methods and survey procedures, yielding small but significant differences in vertical accuracy. One hundred-nine sites were positioned by static occupations, and thirty-six by the USGS Airborne Height Finder (AHF) System. The AHF surveys, with repeat observations at each site, provide heights within 4-5 cm of datum. A majority of the static surveys employed long duration observations, typically 48 hours, producing heights within 2 cm of datum. The 1997 Florida Bay Survey is estimated to be within 3-4 cm of datum, due to different procedures and the available reference control.

Beginning in 1998, both the AHF and the static gage surveys were tied to ground stations of the AHF Control Network, developed by USGS and referenced to NAD 83(97) via the NGS MIA3 Continuously Operating Reference Station (CORS). This common reference frame allows both survey methods to achieve a level of datum consistency previously unattainable in the Everglades region. For the first time in this harsh and geodetically challenging environment, the geospatial relationship of even the most remote monitoring sites has been reliably determined.

Attribute_Definition:
A four character ID of the geodetic reference point. Assigned by USGS/NMD, this identifier refers specifically to the point measured, not the associated gage site. After a prefix of "G" the existing gage ID is incorporated as the 2nd, 3rd and sometimes the 4th character. Alternately, the 4th character may be assigned to create a unique ID where none existed before. The 4th character defaults to an "X" when not needed to replicate the existing ID, or achieve uniqueness.
