Dataset Description: Saginaw County, MI 2016 LiDAR project called for the Planning, Acquisition, processing and derivative products of LIDAR data to be collected  at a nominal pulse spacing (NPS) of 0.7 meter.  Project specifications are based on the U.S. Geological Survey National Geospatial Program Base LIDAR Specification, Version 1.0.  The data was developed based on a horizontal projection/datum of Michigan State Plane South, NAD83, international feet and vertical datum of NAVD1988 (GEOID12A), international feet.  LiDAR data was delivered in RAW flight line swath format, then processed to create Classified LAS 1.2 Files formatted to 991 individual 5000 foot X 5000 foot tiles. Corresponding Intensity Images and Bare Earth DEMs tiles were created with the same 5000 foot X 5000 foot tile schema. Breaklines were produced in Esri geodatabase format.
Ground Conditions: LiDAR was collected in spring of 2015, while no snow was on the ground and rivers were at or below normal levels.  In order to post process the LiDAR data to meet task order specifications, Spicer Group Inc established a total of 120 Land Cover control points (52 QC checkpoints, 68 calibration control points) which were used to calibrate the LIDAR to known ground locations established throughout the Saginaw County, MI project area. 28 additional check points were surveyed by Kucera for the accuracy check of the initial acquisition. these 28 points have been added to the NVA LiDAR and DEM accuracy reports.</abstract><purpose>To acquire detailed surface elevation data for use in conservation planning, design, research, floodplain mapping, dam safety assessments and elevation modeling, etc. Classified LAS files are used to show the manually reviewed bare earth surface. This allows the user to create Intensity Images, Breaklines and Raster DEM. The purpose of these lidar data was to produce high accuracy 3D hydro-flattened Digital Elevation Model (DEM) with a 2 foot cell size. These raw lidar point cloud data were used to create classified lidar LAS files, intensity images, 3D breaklines, and hydro-flattened DEMs as necessary.</purpose><supplinf>CONTRACTOR: Spicer Group Inc
Lidar data were acquired by Kucera International Inc.
All follow-on processing was completed by the prime contractor.</supplinf></descript><timeperd><timeinfo><rngdates><begdate>20150324</begdate><enddate>20150417</enddate></rngdates></timeinfo><current>ground condition</current></timeperd><status><progress>Complete</progress><update>None planned</update></status><spdom><bounding><westbc>-84.3995620600000</westbc><eastbc>-83.6676117500000</eastbc><northbc>43.5716650600000</northbc><southbc>43.1168418800000</southbc></bounding><lboundng><leftbc>13114641.521</leftbc><rightbc>13310000.000</rightbc><topbc>755000.000</topbc><bottombc>590000.000</bottombc></lboundng></spdom><keywords><theme><themekt>None</themekt><themekey>Elevation data</themekey><themekey>Lidar</themekey><themekey>Breaklines</themekey></theme><place><placekt>None</placekt><placekey>Michigan</placekey><placekey>MI</placekey><placekey>Saginaw County</placekey></place></keywords><accconst>No restrictions apply to this data.</accconst><useconst>None.

Class 2 LiDAR was used to create a bare earth surface model.  The surface model was then used to heads-up digitize 2D breaklines of inland streams and rivers with a 100 foot nominal width and Inland Ponds and Lakes of 2 acres or greater surface area.
Elevation values were assigned to all Inland Ponds and Lakes, Inland Pond and Lake Islands, Inland Stream and River Islands, using TerraModeler functionality.
Elevation values were assigned to all Inland streams and rivers using ESRI Software.
All ground (ASPRS Class 2) LiDAR data inside of the collected inland breaklines were then classified to water (ASPRS Class 9) using TerraScan macro functionality.
The breakline files were then translated to ESRI File-Geodatabase format using ESRI conversion tools.</procdesc><srcused>MI_SaginawCo_2015_LiDAR_ctrl</srcused><srcused>MI_SaginawCo_2015_LiDAR</srcused><procdate>2018</procdate><srcprod>Hydro Flattened Breaklines</srcprod><proccont><cntinfo><cntorgp><cntorg>Spicer Group Inc</cntorg><cntper>Nathan Shepherd</cntper></cntorgp><cntaddr><addrtype>mailing and physical</addrtype><address>6600 Peachtree Dunwoody Road, building 400, Suite 108</address><city>Atlanta</city><state>GA</state><postal>30328</postal><country>USA</country></cntaddr><cntvoice>678-585-6501 ex304</cntvoice><cntfax>678-585-6501</cntfax><cntemail>nathans@spicergroup.com</cntemail><hours>Monday through Friday 8:00 AM to 5:00 PM (Eastern Time)</hours><cntinst>If unable to reach the contact by telephone, please send an email.
