<p class="MsoNormal">Hello GIS Users,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The National Hydrography Dataset (NHD) was recently updated in the
<a href="http://geodata.dep.state.fl.us/">FDEP Open Data Portal</a> and MapDirect.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">DataMiner Name – Florida NHD<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The latest update is a snapshot of the federal NHD layer as of January 17, 2017. Once downloaded, the database undergoes a series of manipulations to prepare it for release including:<o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoNormal" style="margin-left:0in;mso-list:l1 level1 lfo1">Projecting into Florida Albers HARN.
<o:p></o:p></li><li class="MsoNormal" style="margin-left:0in;mso-list:l1 level1 lfo1">Creation and population of the Parent_Field for Flowlines<o:p></o:p></li><li class="MsoNormal" style="margin-left:0in;mso-list:l1 level1 lfo1">Download, preparation and integration of the Board on Geographic Names (BGN) Geographic Names Information System (GNIS) variant names tables for the state of Florida features.
<o:p></o:p></li><li class="MsoNormal" style="margin-left:0in;mso-list:l1 level1 lfo1">Addition of relationship classes between Flowlines, Areas, Waterbodies and Variant Names<o:p></o:p></li><li class="MsoNormal" style="margin-left:0in;mso-list:l1 level1 lfo1">Addition of relationship classes between Flowlines and Areas, and Flowlines and Waterbodies<o:p></o:p></li><li class="MsoNormal" style="margin-left:0in;mso-list:l1 level1 lfo1">Addition of the NHD100K database<o:p></o:p></li><li class="MsoNormal" style="margin-left:0in;mso-list:l1 level1 lfo1">Update of the symbology layer used for DataMiner<o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Notable edits in the 24K NHD database since the previous download were in the following subbasins:
<o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoNormal" style="margin-left:0in;mso-list:l0 level1 lfo2">Florida Southeast Coast (03090206)<o:p></o:p></li><li class="MsoNormal" style="margin-left:0in;mso-list:l0 level1 lfo2">Apalachicola (03130011)<o:p></o:p></li><li class="MsoNormal" style="margin-left:0in;mso-list:l0 level1 lfo2">St. Andrew-St. Joseph Bays (03140101)<o:p></o:p></li><li class="MsoNormal" style="margin-left:0in;mso-list:l0 level1 lfo2">and assorted network improvements made by USGS staff in St. Andrew-St. Joseph Bays (03140101).
<o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As before, in the symbology layer, NHD24K labels for Flowline, Areas and Waterbodies were grouped by scale and size. These Label Classes are fully customizable from the featureclass properties Labels tab if adjustments are needed. By categorizing
the labels, only the largest features are labelled when zoomed way out. When you zoom closer in (larger scale), the labels of the smaller lakes, bays and other features appear.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This layer is available under the ‘Water’ and ‘WRM’ buttons in DataMiner.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also, when you add the data from DataMiner, you will notice the NOAA-NFHAP Estuarine Zones has been bundled with the NHD layer file. More information on the National Fish Habitat Action Plan (NFHAP) estuarine zones can be found in the metadata.
