This data set represents realtime U.S. Geological Survey streamflow sampling stations in the state of Florida. Approximately 5,000 of the 6,900 U.S. Geological Survey sampling stations in the United States are equipped with telemetry to transmit data on streamflow, temperature, and other parameters back to a data base for real-time viewing via the World Wide Web. A map of the realtime stations is produced every day. (Note: There are other stream gauges in Florida that aren't captured in this USGS data. Potential sources for other gauge locations would be the National Weather Service and/or Water Management Districts.)
The primary purpose of this coverage is to produce an imagemap for use on the World Wide Web.

GeoPlan relied on the integrity of the attribute information within the original data.
All locations are points.
This coverage includes only those stations with data actually being served on the WWW at the time of compilation. Some stations -- and sometimes whole states -- may be excluded because of temporary webserver or network problems. In addition, a station with data may not be shown on the map if its name and location are not yet in the master list.
Latitudes and Longitude are specified to the nearest second. The position is determined from 1:24,000-scale maps, where available, but other lower scale (i.e. less resolution) maps may be used also.
This data is provided 'as is' and its vertical positional accuracy has not been verified by GeoPlan
Spatial and Attribute Information
Each USGS District Office serves the realtime data of the stations it services. A list of these pages may be seen at http://water.usgs.gov/realtime.html Every District realtime page (some have several pages) contains a list of the stations for which realtime data are available and a link to the data for each station. Every day, an automatic process retrieves the realtime pages from each District and parses them to find the stations served and the URL for each station's data. The station numbers on this list are matched against a master list of USGS stations to find the station name and the latitude/longitude of each realtime station. This information is used to prepare an updated point coverage.
GeoPlan downloaded this data on March 26, 2009 from the National Atlas web site (http://nationalatlas.gov/atlasftp.html?openChapters=chpwater#chpbio). When downloaded the data was in the following projections: NAD 83. The data was projected to FGDL Albers NAD 83 HARN - Upcased all fields - Added DESCRIPT based on STANAME - Added FGDLAQDATE based on date downloaded from source - Deleted fields AREA, PERIMETER, REALSTX_, REALSTX_ID, DATUM - Renamed dataset from realstx to strstx_mar09 - Set FLOW and STAGE field = 0 - Set TIME and TIME_UTC to "SEE REALTIME LINK FOR DATA"

Gage height (measured in feet). This is the height of the water in the stream above a reference point. Gage height refers to the elevation of the water surface in the specific pool at the streamgaging station, not along the entire stream. Gage height also does not refer to the depth of the stream. Measurements of gage height are continually recorded by equipment inside a gagehouse on the streambank. This field is set to 0 by GeoPlan, realtime data should be gathered by following the link in the table associated with the gauge.

A percentile is a value on a scale of one hundred that indicates the percent of a distribution that is equal to or below it. For example, on the map of daily streamflow conditions a river discharge at the 90th percentile is equal to or greater than 90 percent of the discharge values recorded on this day of the year during all years that measurements have been made. In general, a percentile greater than 75 is considered above normal, a percentile between 25 and 75 is considered normal, a percentile less than 25 is considered below normal. In some hydrological studies, particularly those related to floods, a variation of the percentile known as the "percent exceedance" is used. It is simply obtained by subtracting the percentile scale value from 100 percent. For example, a discharge at the 75th percentile is the same as a discharge at the 25th percent exceedance (100-75=25).

Floodstage is the gage height value when the river is considered to be flooding. See the attribute STAGE for a full description of gage height.

The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.
