Data is distributed in FGDL by county and vendor. Currently, contours are available via FGDL for the following nine counties: Broward, Dade, Duval, Glades, Martin, Monroe, Okeechocbee, Palm Beach, St. Lucie. Three vendors, Ch2mHill, CDM and Merrick, created the contours for the above counties. This metadata represents a generic metadata for all vendors. After downloading data from FGDL, please see the individual metadata associated with the data for vendor specific process steps. </td> </tr> </table> </td> </tr> <tr><td></td></tr> <tr> <td> <pre> DATA SOURCE(S): Florida Division of Emergency Management SCALE OF ORIGINAL SOURCE MAPS: Varies GEODATASET EXTENT: Florida Counties<br /> PUBLICATION DATE: 2009 TIME PERIOD OF CONTENT: Begin Date: 20070908 End Date: 20080125 DOWNLOAD LINK: <A href="http://www.fgdl.org/metadataexplorer/explorer.jsp">http://www.fgdl.org/metadataexplorer/explorer.jsp</A> </pre> </td> </tr> </table> <P> <strong><b>FEATURE ATTRIBUTE TABLES:</b></strong> </P> <pre>Datafile Name: TOPO2FT</pre> <table width="75%" cellspacing="0" cellpadding="0" border="0"> <tr align="left"> <td> ITEM NAME </td> <td>WIDTH</td> <td>TYPE</td> <td>N.

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.
