Abstract: Mobile County LiDAR
Purpose:
Mobile County, Alabama requires efficient data to effectively plan and manage county infrastructure. 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.
Access_Constraints:
Data are to be used by Mobile County personnel only unless a written request to the County POC has been approved.
Use_Constraints:
Users must abide by the terms of the non-disclosure agreement or the data sharing agreement under which the geospatial data were obtained.

Process_Description:
Ground Control This Geodetic Control Survey was conducted to support Light Detection and Ranging (LiDAR) data in accordance with the National Digital Elevation Program (NDEP) and the American Society for Photogrammetry and Remote Sensing (ASPRS) guidelines. 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.

Process_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 12th 2014 through January 22th 2014.

Process_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-unclssified, 2-ground, 3-lowpoints/noise, 9-water
Process_Date: 20140611
Logical_Consistency_Report:
Topological integrity of the data was validated using the validation tools in ESRI's ArcGIS 10.1.
