These data are believed to be logically consistent, though no tests were performed. |
This dataset was created based on the narrative unit descriptions as listed in the Federal Register, 50 CFR Part 17, Designation of Critical Habitat for the Gulf Sturgeon; Final Rule, February 28, 2003. Omissions of river distributaries may be possible due to the extent of source data (NHD) and because a number of the smaller streams are not named and easily identifiable. Based on the legal narrative unit descriptions in the Federal Register, all distributaries are included; however, they may not be graphically represented in this dataset. |
GeoPlan relied on the integrity of the attribute information within the original data. |
Critical habitat identifies specific areas that are essential to the conservation of a listed species, and that may require special management considerations or protection. Section 7(a)(2) of the Act requires that Federal agencies ensure that actions they fund, permit, or carry out are not likely to result in the destruction or adverse modification of critical habitat. The regulatory effect of the critical habitat designation does not extend beyond those activities funded, permitted, or carried out by Federal agencies. State or private actions, with no Federal involvement, are not affected. |
This dataset is provided for illustrative purposes only. This dataset does NOT represent the legal definition of riverine critical habitat units for Gulf sturgeon. For the precise legal definition, please refer to the narrative unit descriptions as listed in the Federal Register, 50 CFR Part 17, Designation of Critical Habitat for the Gulf Sturgeon; Final Rule, February 28, 2003. |
Horizontal accuracy was not tested; however, data was created using National Hydrography Dataset which is assumed to have horizontal accuracy. |
Vertical accuracy was not tested. |
This dataset is provided for illustrative purposes only. This dataset does not represent the legal definition of riverine critical habitat units for Gulf sturgeon. For the precise legal definition, please refer to the narrative unit descriptions as listed in the Federal Register, 50 CFR Part 17, Designation of Critical Habitat for the Gulf Sturgeon; Final Rule, February 28, 2003. |
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.

This data set was created using ArcView 3.2a The process steps for creating the final Gulf sturgeon riverine critical habitat units were: 1. NHD arc and route.reach files were brought into the view for each basin covered by the final critical habitat. 2. Records in the route.reach files were selected by querying on the name field. Additional unnamed records (mainly distributaries) were selected within the view using the selector tool. 3. Records in the arc files were selected using the "Select by theme..." command, choosing all records that were completely within the route.reach files. The selected records were visually checked to ensure that only river centerlines were included. 4. Using the X-Tools extension "merge themes" command, all selected records from the NHD arc files were combined into the stg_ch_final.shp file. 5. Distributaries that were not included in the NHD arc files but were included in the Federal Register maps or DeLorme state gazetteers were added to the shapefile with on-screen digitizing. 6. Using the narrative unit descriptions from the Federal Register, some arcs were spilt and parts were removed. This only occurred in units where the highest river reach included stopped at a road crossing. The roads layer used to determine this stopping point is from the ESRI Sample Data and Maps, CD Volume 5, Southern U.S., August 1999. Process Date: 20021126 |
