2 foot contours derived from 2009 Lidar.
<div>**Spatial Data is not being updated**</div><div><br /></div>Two-foot contours were produced by the City of Dallas from digital elevation model (DEM) rasters. These DEM rasters were generated from LiDAR points collected in spring 2009 by Sanborn Map Company for the Texas Water Development Board. The contour elevation values are in feet and reference the North American Vertical Datum of 1988 (NAVD88). The contours meet National Map Accuracy Standards at 2-foot intervals.
