* » Abstract |
The LIDAR survey presents digital elevation data sets of a bald earth surface model and 2ft interval contours covering Bayfield County, Wisconsin. The LIDAR data was acquired in March of 2009 using an Optech ALTM 3100EA LIDAR system. The spatial coordinate system is Wisconsin State Plane Bayfield North (4801) in meters, NAVD88 in meters, using the Geoid03 model. Original contact information: Contact Name: Scott Galetka Contact Org: Bayfield County Land Records Department Title: Land Information Officer Phone: 715-373-6156 Email: SGaletka@bayfieldcounty.org |
* Purpose |
The LIDAR surface models and contours depicts geographic features on the earth's surface and is intended for reference within a Geographic Information System environment. |

» Description |
The production of LIDAR bald earth DEM's and contours requires a LIDAR survey, LIDAR sensor calibration, data processing, ground control and ortho-rectified images. An Optech ALTM 3100EA LIDAR system was used flying at 4000ft agl with a 21deg scan angle and 40% sidelap for an avg raw point density of 2.6ft. |

» Description |
The NOAA Office for Coastal Management (OCM) received topographic LAS files with no metadata. The files contained LiDAR elevation and intensity measurements. The points were classed as 'never classified' or unclassified. The data arrived in Wisconsin State Plane Bayfield North (4801) and in NAVD88 in feet. 1. Data was received as all points unclassified. Classified with an algorithm on all LAS files to find ground points. 2. All LAS files were then shifted vertically from NAVD88 to a ellipsoidal (2003) datum 3. All LAS files were then shifted horizontally from SP83 4801 to Geographic decimal degrees. 4. The data was merged into one large LAS file then retiled to better serve the OCM system. 5. Metadata was created, along with a KMZ for the project and ancillary information provided in metadata record. |
