  • 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.
  • This map is available on NOAA 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.

    1. 1. U.S. Department of the Interior U.S. Geological Survey LiDAR meets WisconsinView Coordinating LiDAR Data in Wisconsin J.C. Nelson, Dr. Sam Batzi, Dr. Howard Veregin, and Ron Wencl
    2. 2. Focused Highlights  Need  Collaboration  Progress  Future
    3. 3. Need  Where can we find Wisconsin LiDAR  Do counties have the infrastructure to host their own data?  Full product delivery @ 2TB
    4. 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. 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. 6. What is the objective?  Single location to retrieve Wisconsin LiDAR data  Start with derived products  Goals to eventually serve all collected data
    7. 7. Web Presence
    8. 8. LiDAR Home
    9. 9. WI DNR Floodplain Mapping
    10. 10. WI DNR LiDAR Inventory
    11. 11. US Interagency Elevation Inventory
    12. 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. 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.
    14. 14. NED
    15. 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
    16. 16. Want more info  WIGICC Elevation Working Group will be meeting after the break  Contact me after WLIA  JC Nelson  608-781-6370  jcnelson@usgs.gov
    17. 17. Questions?
