Abstract:
The Breakline vectors were developed from the LiDAR points to define hard and soft breaklines, mostly hydrography, in the terrain surface, as part of the Lafayette County 2011 lidar Project.
Purpose:
The 2011 breaklines dataset contains the hydrographic breaklines necessary for terrain surface development. This dataset establishes the deviation parameters for the development of derivative terrain data. File formats include: ESRI shapefile and AutoCAD DWG format.
Supplemental_Information:
Coupled with the classified lidar point cloud this data set is the 2011 digital terrain model.

Vertical_Positional_Accuracy_Report:
Based on tests conducted by staff from Ayres Associates:
Survey grade elevations were taken in the project area in five different types of cover. These elevations were compared with the LiDAR terrain elevation. RMSE results: Overall - 0.431983865

Process_Step:
Process_Description:
Breaklines for this project utilized a process called Lidargrammetry.  Lidargrammetry involves manipulating the LiDAR data’s intensity information to create a metrically sound stereo environment.  From this generated imagery dependable breaklines can be photogrammetrically compiled.  This capability allows for high-accuracy terrain data from LiDAR without supplemental imagery.
