Purpose:

The purpose of this project is to provide professional surveying and mapping services

to collect and deliver topographic elevation data derived from multiple return light

detection and ranging (lidar) measurements for areas in southeast / coastal Georgia.

These data are intended for use in coastal management decision making, including

applications such as sea level rise and coastal flood mapping. Lifts were planned

to meet project specifications and were flown under cloud-free conditions in order

to collect LiDAR points at an average of 1.0 meter point spacing. This allows the

user to create Intensity Images, Break Lines, and fully Classified LiDAR LAS files.

Classified LAS files are used to show the manually reviewed bare earth surface.

Any additional classification include Class 1 - unclassified, Class 2 - ground

surface, Class 4 - medium Vegetation, Class 5 - High Vegetation, Class 7 -

low point (noise) and Class 12 - Overlap points.

Data Quality

Accuracy:

The project area requires LiDAR to be collected on average of 1.0 meter point spacing

or better and vertical accuracy of 18.0 centimeters RMSE or better to support 2' contour

generation when combined with breaklines.
Vertical Positional Accuracy:

Classified LAS files were tested by Photo Science for both vertical and horizontal

accuracy. All data is seamless from one tile to the next, no gaps or no data areas.

The vertical unit of the data file is in decimal feet with 2-decimal point precision.

Creation of other deliverables based on Classified LAS files is another check of the data.

; Quantitative Value: 0.185 meters, Test that produced the value: RMSE in feet
Completeness Report:

Datasets contain complete coverage of tiles.
Conceptual Consistency:

Classified LAS files were tested by Photo Science for both vertical and horizontal accuracy.

All data is seamless from one tile to the next, no gaps or no data areas. Creation of other deliverables

based on Classified LAS files is another check of the data.

Process Steps

Process Step 1

CC ID: 1134370
Description:

Applanix software was used in the post processing of the airborne GPS and

inertial data that is critical to the positioning and orientation of the

sensor during all flights. POSPac MMS provides the smoothed best estimate

of trajectory (SBET) that is necessary for Optech's post processor to develop

the point cloud from the LiDAR missions. The point cloud is the mathematical

three dimensional collection of all returns from all laser pulses as determined

from the aerial mission. At this point this data is ready for analysis,

classification, and filtering to generate a bare earth surface model in which

the above ground features are removed from the data set. The point cloud was

manipulated within the Optech software; GeoCue, TerraScan, and TerraModeler

software was used for the automated data classification, manual cleanup, and

bare earth generation from this data. Project specific macros were used to

classify the ground and to remove the side overlap between parallel flight

lines. All data was manually reviewed and any remaining artifacts removed

using functionality provided by TerraScan and TerraModeler. Breaklines were

used to reclassify lakes and ponds and inland drains. Data was then run through

additional macros to ensure deliverable classification levels matching LAS ASPRS

Classification structure. GeoCue functionality was then used to ensure correct

LAS Version. In house software was used as a final QA/QC check to provide LAS

Analysis of the delivered tiles.
