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. dateTime: DateTime: 2014-05-10T00:00:00 processStep: (LI_ProcessStep) description: Aerial LiDAR Acquisition: Aerial data collection was acquired, in one (9) mission, using the ALS70 SN# 7123 at an altitude of 5500 ft. 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. Data acquisition was collected January 12, 2014 through January 22, 2014. dateTime: DateTime: 2014-01-22T00:00:00 processStep: (LI_ProcessStep) description: LIDAR PROCESSING: - LiDAR Calibration:Initial processing of the GPS data was processed using Inertial Explorer. 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-unclassified, 2-ground, 3-lowpoints/noise, 9-water dateTime: DateTime: 2014-06-11T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received the files in las format from the City of Mobile GIS office. The files contained lidar elevation and intensity measurements. The data were in Alabama State Plane West coordinates (0102, feet) and NAVD88 heights (Geoid12A, feet). OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. LAS files were compressed to laz format using laszip. 2. Elevation outliers were eliminated, above 2,000 ft and below -50 ft, as these were deemed erroneous. 3. Class 3 (low vegetation) was removed as it was not part of the project specifications, furthermore these points were found to only be located in open water. 4. Reclassified all Class 11 points to Class 15 as this does not match the NOAA OCM classification scheme. 5. Data were converted from Alabama State Plane West coordinates (ft) with NAVD88 heights (ft) to geographic coordinates (decimal degrees) with ellipsoid heights (m). dateTime: DateTime: 2015-11-30T00:00:00 processor: (CI_ResponsibleParty) organisationName: Office for Coastal Management role: (CI_RoleCode) processor source: (LI_Source) description: Source Contribution: LiDAR, Digital Elevation Model, Breaklines | Source Geospatial Form: LAS | Type of Source Media: Portable HardDrive scaleDenominator: (MD_RepresentativeFraction) denominator: 1200 sourceCitation: (CI_Citation) title: Mobile County LiDAR date: (CI_Date) date: 2014-10-21 dateType: (CI_DateTypeCode) publication sourceExtent: (EX_Extent) temporalElement: (EX_TemporalExtent) extent: TimeInstant: timePosition: 2014-10-21 processStep: (LI_ProcessStep) description: The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
