Certain scale datasets are not suitable for some project, analysis, or modelling 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.

In addition to the availability of complete 7.5-minute data, efficient processing methods were developed to filter production artifacts in the existing data, convert to the NAD83 datum, edge-match, and fill slivers of missing data at quadrangle seams.UnknownCounties with high pixel values: 1. Clay (ned10) range 0-90 2 pixels = 255 2. Duval (ned16) range 0-57 3 pixels = 255 3. Escambia (ned17) range 0-103 12 pixels = 254 110 pixels = 255 4. Layfayette (ned34) range 0-55 7 pixels = 255 5. Pinellas (ned52) range 0-30 1 pixel = 255 6. Santa Rosa (ned57) range 0-90 2 pixels = 254 22 pixels = 255 The six counties with abberrant values were processed to eliminate the spikes in the data. Each GRID was visually inspected to identify where the pixel values of 255 were located. In each GRID, the high values were in the ocean and were surrounded by pixel values of zero on each side. Therefore, the pixel values of 255 were reclassified to zero. Counties with an irregular area: (looks like higher resolution quads) 1. Calhoun (ned07) 2. Dixie (ned15) 3. Gilchrist (ned21) 4.

The 7.5-minute elevation data for the conterminous United States are the primary initial source data. In addition to the availability of complete 7.5-minute data, efficient processing methods were developed to filter production artifacts in the existing data, convert to the NAD83 datum, edge-match, and fill slivers of missing data at quadrangle seams. One of the effects of the NED processing steps is a much-improved base of elevation data for calculating slope and hydrologic derivatives. The specifications for the NED 1 arc second and 1/3 arc second data are: Geographic coordinate system Horizontal datum of NAD83, except for AK which is NAD27 Vertical datum of NAVD88, except for AK which is NAVD29 Z units of meters.Only 24 Metadata records are currently included in the Dynamic Metadata. The bounding coordinates requested include more than 24 records so this metadata is the generic metadata for the whole dataset.Microsoft Windows 2000 Version 5.0 (Build 2195) Service Pack 4; ESRI ArcCatalog 8.3.0.800usgs_ned12868850228806069434691-88.064396-79.27377931.26338324.3192471enFGDC Content Standards for Digital Geospatial MetadataFGDC-STD-001-1998local timehttp://www.esri.com/metadata/esriprof80.htmlESRI Metadata ProfileCustomer Services RepresentativeEROS Data Centermailing and physical addressSioux FallsSD57198
