Description:
Abstract:
The Bare Earth DEM was developed from LAS points and breaklines collected from a LiDAR flight flown in the Spring of 2010, as part of the Juneau County 2010 Project.  The DEM is a raster data set in ESRI GRID format with an X, Y, Z value located at the center of each 10 ft. by 10 ft. cell.  The DEM was generated from a DTM meeting ASPRS class II Standards.
Purpose:
The 2010 Bare Earth two-Foot DEM was developed as a derivative product for use in general surface modeling and depiction.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
None
Logical_Consistency_Report:
Each pixel in the ESRI GRID contains a value representing relative elevation.  Each pixel represents a 10 foot by 10 foot area.
Completeness_Report:
The digital elevation model covers all of the project area with no gaps or omissions.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The data set is derived from a DTM that meets National Map Accuracy Standards for the scale 1:600.  The horizontal accuracy is +/- 1.5 feet for well defined points, at a ninety percent confidence level.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Based on tests conducted by staff from Juneau County:
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 - 0.2895
