Description:

Abstract:

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 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 real-time 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.) This is an update to the strstx_nov04 layer.

Purpose:

The primary purpose of this coverage is to produce an imagemap for use on the World Wide Web.

Supplemental_Information:

The U.S. Geological Survey (USGS) Water Resources program, in cooperation with more than 800 Federal, State, and local agencies, operates a streamflow gaging-station network to collect nationally consistent information about the Nation's water resources and to help define and manage those resources. Individual stream-gaging stations are supported for specific purposes, such as water allocation, reservoir operations, or the regulation of permit requirements. However, the data are also used for flood hazard mitigation by the National Weather Service, the U.S. Army Corps of Engineers, and the Federal Emergency Management Agency, for resource planning, for infrastructure design of reservoirs and dams, and for many other purposes.
More than Over 4,000 of the USGS's approximately 7,000 stream gages are equipped with telemetry that transmits a reading of stream depth to an office by satellite or telephone. Computers in the office convert the depth reading to a value for flow and plot a graph of flow versus time, usually showing the previous 7 days. Some stations also transmit values for temperature, conductance, or other parameters. The data typically are updated every 4 hours, but this can vary depending on the equipment used and the flow status. More frequent updates may be made in times of flooding. Realtime hydrologic data are provisional and have not been reviewed or edited. Each station record is considered provisional until the data are published, which usually occurs within 6 months of the end of the water year (September 30). Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

GeoPlan relied on the integrity of the attribute information within the original data.

Logical_Consistency_Report: All locations are points.

Completeness_Report:

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.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

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.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

This data is provided 'as is' and its vertical positional accuracy has not been verified by GeoPlan

Process_Description:

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.
CLASS values for the flow are:

       le 0  Not valid (internal use)
        1    New minimum
        2    ge old minimum and le 5th percentile

Process_Description:

GeoPlan downloaded this data on May 02, 2011 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. During the QA/QC process the following steps were undertaken:
- Selected points in the State of Florida via an attribute selection (ST = "FL") - Deleted empty fields (AREA, PERIMETER) and redundant fields (REALSTX_) - Deleted fields related to the river conditions at the time of download (CLASS, FLOW, STAGE, PERCENTILE, TIME, AND TIME_UTC). - Added DESCRIPT based on STANAME - Upcased all fields except URL - Added FGDLAQDATE based on date FGDL acquired the data from the source - Renamed dataset from realstx to strstx_apr11

Resource_Description: DOWNLOADABLE DATA

Distribution_Liability:

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.
