This dataset was developed to support Mobile County. The scope involved the acquisition of USGS Quality Level 2 LiDAR data to be processed, classified to produce a new countywide DEM and one foot elevation contours for the entire 1402 square mile Mobile County Project Area. Data are to be used by Mobile County personnel only unless a written request to the County POC has been approved.Users must abide by the terms of the non-disclosure agreement or the data sharing agreement under which the geospatial data were obtained.Chris Cannon, Production Manager (Atlantic), James L.

A GPS control network was performed for the purposes of establishing a three-dimensional coordinates on each of the base station locations. The control network included a combination of a National Geodetic Survey (NGS) Control Monument (MOB AP STA A1), National Geodetic Survey (NGS) CORS (AL84, AL90, AL92, ALDI, ALM) ,Mobile Control Monuments (MCC1062, MCC1067, MCC1070, MCC1072, MCC1073, MOB1000, MOB1008, MOB1009, MOB1011, MOB1023, MOB1031, MOB1034) and a capped iron found (CIPF). GPS observations at all ground control points in the network were made with Leica System 500 dual frequency GPS-receivers w/ Leica AT502 antenna and a NovAtel DL 4=L1L2 receiver w/ NovAtel NOV702 3.00 antenna between April 30, 2014 and May 2, 2014. 20140510GrafNet 8.30.2105AtlanticScott JonesMissions Operations Managermailing and physical address

MSL. This was to support a 2.0 ppm^2 LiDAR point cloud. Airborne GPS and IMU data was collected during the acquisition and supported by Topcon Viper GPS base station that occupied NGS monument MOBARP.

The solution file was generated and ALSPP software was used to generate georeferenced laser returns which were then processed in strip form allowing for the QC of the overlap between strips (lines). The data from each line were combined and automated classification routines run to determine the initial surface model. This initial surface model was then verified to the LiDAR test points. LiDAR Classification: The calibrated LiDAR data was run through automated classification routines and then manually checked. The data was classified into the following classes: 1-unclssified, 2-ground, 3-lowpoints/noise, 9-water20140611nertial Explorer 8.5, ALSPP 2.75, TerraScan 14.015, TerraModel 14.002, TerraMatch 14.007, GeoCue 2013.1.45Topological integrity of the data was validated using the validation tools in ESRI's ArcGIS 10.1.0Projection ConsistencyGlobal Mapper ver.11.02 was used to validate that the correct projection information was applied to each image.File FormatImage Station Raster Utility - Display Header application was used to validate file format parameters such as: 4-band, 8-bits per band (RGBI), and pixel readout starts in northwest corner as (0,0).All work was done in cordination with Mobile County Contract.LiDAR Vertical Accuracy of the bare-earth data was assessed and reported in accordance with the guidelines developed by the NDEP and subsequently adopted by the ASPRS; - FVA<= 0.60 ft ACCZ, 95% (030 ft RMSEZ) - CVA<= 0.80 ft ACCZ, 95% (0.41 ft RMSEZ) - SVA<= 0.80 ft ACCZ, 95% (0.41 ft RMSEZ) Ninety-Five (111) surveyed points were measured for the purpose of assessing the accuracy of the Mobile County data.
