This slide show describes the Minnesota Elevation mapping project

1. Minnesota Elevation Mapping Project Tim Loesch Minnesota Department of Natural Resources Wisconsin Land Information Association Annual Conference 2/22/2011 Minnesota Elevation Mapping Project

2. Minnesota Elevation Mapping Project Elevation Mapping in Minnesota How did we get here? Where are we now? Where are we going? Minnesota Elevation Mapping Project

3. Minnesota Elevation Mapping Project How did we get here? 2000 – 2005 Small, non coordinated projects 35 – 1500 square miles County based (typically) Proprietary Data Not a lot of knowledge Bare earth and contours 2/22/2011 Minnesota Elevation Mapping Project

4. 2/22/2011 Minnesota Elevation Mapping Project Minnesota Elevation Mapping Project How did we get here? 2006 State received $500k for Red River Project Cooperative project involving MnDNR MnDOT White Earth Tribal Council Wild Rice Watershed District Corp of Engineers

5. Minnesota Elevation Mapping Project How did we get here? Digital Elevation Committee Governor’s Council on Geographic Information subcommittee Goal – to build a statewide, publicly available high accuracy DEM Provide Technical Guidance to Organizations collecting LiDAR data 2/22/2011 Minnesota Elevation Mapping Project

6. Minnesota Elevation Mapping Project Hard Realizations Money was tough to come by Would likely be a piece-meal effort Develop Standards to ensure data compatibility across collects Provided guidance and technical expertise Required “champion” to push at the legislative level State employees have limited ability to push legislative efforts 2/22/2011 Minnesota Elevation Mapping Project

8. 2/22/2011 Minnesota Elevation Mapping Project Minnesota Elevation Mapping Project Towns Evacuated Stockton, Houston, Elba, Minnesota City and portions of Winona Whitewater State Park 4,200 Homes Damaged 7 Deaths $67 Million Damage

9. 2/22/2011 Minnesota Elevation Mapping Project Minnesota Elevation Mapping Project 7 Counties Declared Disaster Areas Steele, Dodge, Olmsted, Wabasha, Winona, Fillmore, Houston Special Legislative Session provided money for flood relief and mitigation And LiDAR…..

10. Minnesota Elevation Mapping Project And things were happening elsewhere… Red River Basin collect 48,000 square miles in MN, ND, SD More counties… 2/22/2011 Minnesota Elevation Mapping Project

11. Minnesota Elevation Mapping Project Clean Water, Land and Legacy Amendment Add a sales tax of 0.375% Outdoor Heritage Fund – 33% Clean Water Legacy Fund – 33% Parks and Trails Fund – 14.25% Arts and Cultural Heritage Fund – 19.75% $240,000,000 annually 2/22/2011 Minnesota Elevation Mapping Project

12. Minnesota Elevation Mapping Project Clean Water Legacy Fund dedicated fund available for clean water projects Convinced legislators of the value of elevation data Project Scope and Costs 40,000 square miles to complete state $8.5 million Supported Funding $2.8 Million FY10 $2.8 Million FY11 2/22/2011 Minnesota Elevation Mapping Project

15. Minnesota Elevation Mapping Project Project Specifications Closely aligned with UGSS LiDAR Base Specs V13 1.5 meter postings Classified LAS Data Vendor Deliverables Point data – LiDAR LAS files Edge of water break lines 1 meter DEM units in meters – break line enforced 2/22/2011 Minnesota Elevation Mapping Project

16. Profile of points - Vegetation 2/22/2011 Minnesota Department of Natural Resources Coniferous Deciduous Deciduous

17. 2/22/2011 Minnesota Elevation Mapping Project Minnesota Elevation Mapping Project Generated Deliverables 2’ Contours Building Polygons Additional Items Each county partner receives a portable hard-drive with a data “package” Set of ArcGIS Tools to work with data Training materials

18. Data will be publicly available Actively exploring web delivery options Web Services Print a map with an Air Photo backdrop with 2’ contours? Clip and Ship products USGS National Elevation Dataset (NED - http://ned.usgs.gov/) Raster DEMs Center for LiDAR Coordination and Knowledge (CLICK) LAS Point Cloud Data (http://lidar.cr.usgs.gov/) 2/22/2011 Minnesota Elevation Mapping Project Minnesota Elevation Mapping Project

19. Minnesota Elevation Mapping Project Great Partnering across all levels of government County and local government GIS Coordinator - data distribution Survey/Engineer – validation points Sharing of existing high-resolution data Federal Cost sharing opportunities to stretch $’s USGS - $415,000 NRCS - $171,000 2/22/2011 Minnesota Elevation Mapping Project

20. Minnesota Elevation Mapping Project Contract/Vendors Master Contract for LiDAR Services Four Vendors were selected based on qualifications and costs that meet USGS Base Specifications 2/22/2011 Minnesota Elevation Mapping Project

21. Minnesota Elevation Mapping Project Contract/Vendors Work Order Requests Can be competitive or directly awarded Same form every time – different geography What do we get out of this Multiple vendors can be deployed at once We don’t put all our eggs in one basket 2/22/2011 Minnesota Elevation Mapping Project
