| Title | Contours and Digital Elevation Model derived from LiDAR, Pierce County, Wisconsin, 2016 |
| Abstract | Houston Engineering Inc. processed high accuracy bare earth LiDAR elevation data acquired from Pictometry in Spring 2015 to derive water breaklines, 2ft Contours and DEMs for Pierce County, Wisconsin. The data covers Pierce county with a small overlap into adjacent Counties. Please refer to the LiDAR dataset metadata for more information in regards to the LiDAR data.
The data are in the NAD1983 HARN WISCRS Pierce County Feet coordinate system.
Houston Engineering Inc. created and delivered these data products to Pierce County in summer 2016:
1. Edge of Water Breaklines
2. DEM
3. Hillshade
4. Two-foot Contours
|
| Purpose | The purpose of the data sets is to represent the bare earth LiDAR dataset in other commonly used formats. |
| Time Period of Content Date | 2016 |
