This data is provided "as is". GeoPlan relied on the integrity of the original data layer s topology. The shapefile is converted to SDC (Smart Data Compression) format using either ESRI SDC Data Development Kit Professional 2 (DDKP2) or tools in ArcGIS. The SDC data set is then loaded into ArcSDE to verify and validate the geometry. |
This data is provided "as is" by GeoPlan and is complete to our knowledge. After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials. Data completeness generally reflects the content of the original Digital Line Graph (DLG) files. |
GeoPlan relied on the integrity of the attribute information within the original data. |
Largest scale when displaying the data: 1:1,000,000. |
U.S. National Atlas Water Feature Areas provides the water feature areas for geographic display and analysis at regional and national levels. |
The geospatial part of this data set was originally extracted from the individual 1:2,000,000-scale State boundary Digital Line Graph (DLG) files produced by the U.S. Geological Survey which have a positional accuracy of 1,720 meters. It was updated several times using various sources whose horizontal positional accuracies are unknown. |
This data is provided 'as is' and its vertical positional accuracy has not been verified by GeoPlan |
THE DATA INCLUDED IN FGDL ARE 'AS IS' AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING. 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 file was originally digitized by the National Mapping Division based on the sectional maps contained in 'The National Atlas of the United States of America' published by the USGS in 1970. The 1:2,000,000-scale Digital Line Graph (DLG) data were merged into a single national hydrography coverage. Where necessary to effect the merge, alignment changes were made. The names were taken from the USGS Topographic 1:100,000-scale maps. For Alaska, the names were taken from the USGS Topographic 1:250,000-scale maps. State lines across water bodies were removed from the national coverage. State attributes were assigned to the features. Some spatial features were added and corrected. Some name attributes were added or corrected. All occurrences of St. were changed to Saint. Extra spaces were removed from the attributes. Hydrographic features for Puerto Rico and the U.S. Virgin Islands were added. A minor adjustment was made to the shoreline in Galveston Bay, Texas. The linear water feature attribute value, Intercoastal waterway, was changed to Intracoastal waterway. Process Date: 200212 |
