Description

The Contour_1ft feature class was created using MARS software. A three foot/three pass gridded surface was used to generate tile based ESRI shape files. The shape files are merged together and topology validation was performed. The ground classified lidar points along with the breaklines lines was used to create the TIN which the contours were generated from.


Summary

One-foot contours created from LiDAR data flown in mid-May of 2011.

Data quality report - Quantitative attribute accuracy
Measure description
LIDAR points were tested for vertical accuracy by comparing their values to known control points.  Ground GPS techniques were used to establish the control locations.  Survey control points were used to validate the accuracy of the LIDAR surface model and effects of filtering algorithms for vegetation removal.  Contour lines were generated and were verified for accuracy against surveyed spot elevations.  Supplemental breaklines were added to more accurately model certain surface features.  This essential validation proves the accuracy of the contours relative to the adjustment of the LIDAR data.
