Metadata Summary

Originator Ramsey County
Abstract Ramsey County contour data set is a linear data set created from a November 2001, Waggoner Engineering, LiDAR airborne survey. The data set resides in a Enterprise Geodatabase format as polylines. Polylines depict two foot contour lines generated from the LiDAR bare earth point data. This data set covers Ramsey County except the City of Saint Paul who maintain thier own DEM data.

Originator Ramsey County
Title Ramsey County Contours
Abstract Ramsey County contour data set is a linear data set created from a November 2001, Waggoner Engineering, LiDAR airborne survey. The data set resides in a Enterprise Geodatabase format as polylines. Polylines depict two foot contour lines generated from the LiDAR bare earth point data. This data set covers Ramsey County except the City of Saint Paul who maintain thier own DEM data.
Purpose Contour lines support many functions including a county wide model for preliminary drainage, street, road and site development plans.

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy The elevation attribute accuracy is based on a November, 2001 LIDAR airborne survey. The point data collected in this manner was tested to meet VMAS mapping accuracy at the 90% confidence level of 1.06 feet when compared against the final delivered DEM.
Logical Consistency Generally linework depicted here was not originally intended to create closed boundaries or polygons.
Completeness Entire Ramsey County coverage except the City of Saint Paul
Horizontal Positional Accuracy The vendor for this project (Waggoner Engineering, Inc.) states in their flight planning documentation that the horizontal accuracy of each point is 1.5 feet.
Vertical Positional Accuracy The verticle accuracy is based on the independent collection of 199 ground surveyd points distributed throughout the project. The comparison for the surveyed determined elevation at each coordinate point and the DEM elevation for the same coordinate, the VMAS mapping accuracy at a 90% confidence level is 1.06 feet. The NSSDA mapping accuracy at a 95% confidence level is 1.20 feet.
Lineage PROCEDURE: LIDAR data set acquired in 2003; converted to TIN and interpolated to 2' contours.
