Lineage

Description
Contours have been derived from a ground model triangulated from the LiDAR returns classified as model keypoints. Points are interpolated on the edges of these triangles at (interval) elevation intervals. Points with equal elevation are then connected with smoothed lines before the lines for each interval are merged to form the final contours. The data is then cut into 1km tiles for delivery

Comments
Contours have been derived from the model keypoints, which are a subset of the classified ground returns. Contours have been interpolated across voids and have not been removed or clipped across water bodies.
