LiDAR meets WisconsinView
Coordinating LiDAR Data in Wisconsin
J.C. Nelson, Dr. Sam Batzi, Dr. Howard Veregin, and Ron Wencl

2. Focused Highlights
 Need
 Collaboration
 Progress
 Future

3. Need
 Where can we find Wisconsin LiDAR
 Do counties have the infrastructure to host
their own data?
 Full product delivery @ 2TB

4. A Solution
 Collaboration between: WIGICC, WI DNR,
WisconsinView, Ayres Associates, SCO,
LION, USGS, and many others.
 WI DNR (Floodplain Mapping) to provide
elevation data to WisconsinView
 WisconsinView to host data for public access
 Other groups (WIGICC, Ayres, SCO, LION,
USGS) helped with coordination effort and to
ensure broad needs are met

5. Why WisconsinView
 WisconsinView has a mission statement that reads,
“Coordinating remote sensing imagery access and
use in the State of Wisconsin.”
 With more and more Wisconsin counties collecting
LiDAR, a centralized location for coordinating LiDAR
data access was desirable. WisconsinView has
stepped up to the plate and is working with WIGICC
and others to make this a reality.

6. What is the objective?
 Single location to retrieve Wisconsin LiDAR
data
 Start with derived products
 Goals to eventually serve all
collected data

10. WI DNR LiDAR Inventory

11. US Interagency Elevation Inventory

12. Progress…
 Server space made available on
WisconsinView
 Data delivery to begin as early as this week
 Informational letter sent to LIOs in Phase 1
counties
 Phase 1: Adams, Brown, Columbia, Crawford,
Grant, Green, Iowa, Jefferson, Juneau,
Kenosha, Lafayette, Monroe, Richland, Rock,
Sauk, Vernon and Waukesha

13. About the data
 5-foot resolution, hydro-flattened, bare-earth DEMs
 Processed by Wi DNR
 WI DNR will be the "source" of elevation data for the 20-or-so grant counties in
southern WI. Federal grant $, so public-domain data.
 Will be in coordinate system that was delivered to DNR
 Possibly two formats: IMG and ArcGrid
 Data will be freely available, like WROC and NAIP imagery.
 Distribution will be by county - again using the "original" data
extent.
 Original metadata from Ayres will be provided, along with the
FEMA metatdata, and the QC report from Ayres. Also a general
description of the DNR workflow will be provided.

15. Immediate Future
 Get all initial data online
 Follow usage stats
 Continue to work towards higher capacity servers
 Follow up with current and potential users to drive the
application
