Wisconsin DNR (floodplain mapping program) will provide DEMs to WisconsinView.Advantages: DNR applies same processing methodology to input data to derive a consistent product. This will minimize differences across county boundaries.More details on data characteristics in a few minutes…A good example of a state agency providing public access to data originally acquired for internal business needs. Katie McMahan (manager of floodplain mapping program) has stepped up to the plate to help make this a reality. Also a federal connection here since the DNR floodplain mapping program is funded by FEMA.
This map is available on WIGICC Web site.WI DNR has datasets for about ½ of WI counties.The phase 1 part of the project covers only the 20 or so counties in the southern part of the state that received CDBG funds for LiDAR.

Also hope to use this data to improve Wisconsin’s NED data, and fill in some of the gaps in coverage.Overall, the initiative will be a win for the federal govt, a win for state/local govt, and a win for the public.

Coordinating LiDAR Data in Wisconsin

Where can we find Wisconsin LiDAR
Do counties have the infrastructure to host
their own data?
Full product delivery @ 2TB
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
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.
What is the objective?
Single location to retrieve Wisconsin LiDAR
Start with derived products
Goals to eventually serve all
Server space made available on
Data delivery to begin as early as this week
Informational letter sent to LIOs in Phase 1
Phase 1: Adams, Brown, Columbia, Crawford,
Grant, Green, Iowa, Jefferson, Juneau,
Kenosha, Lafayette, Monroe, Richland, Rock,
Sauk, Vernon and Waukesha
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
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.
