Description:
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 Fond Du Lac County 2011 lidar
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.

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: 0.343

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.
