  3. TIM LOESCH MN.IT at DNR PROJECT STATUS

  4. NANCY RADER MN.IT at MnGeo INFORMATION AND DATA DOWNLOAD

  5. INFORMATION Which areas are available? • LiDAR info page:www.mngeo.state.mn.us/chouse/elevation/lidar.html • State status map • Hillshade status map • Lists of counties by project area • Facebook pagefor latest QA/QC status

  6. INFORMATION What help is available? • Helpfiles on FTP site • Readme & Watch me • LAS & neutral format • Tile index maps • Facebook comments • Metadata • Flight lines & dates • Emailclearing.house@state.mn.us

  7. DATA DOWNLOAD – CURRENT OPTIONS MnGeo FTP • County zipfile: Geodatabase format • Tile folders • 1/16 of USGS quad, grouped by county(likely will change to be grouped by 250k sheet) • Index maps show tile boundaries and filenames • Geodatabase or raw format (LAS/LAZ) • Checklist of products within gdb files

  8. DATA DOWNLOAD – POTENTIAL FUTURE OPTIONS DRAFT options being considered by MnGeo and DNR • Interface in addition to FTP • Link to DNR’s viewer so users can see the data prior to download • Tailor download to layers and geography that the user needs • Download tiles by selected area e.g., city, watershed, user-specified polygon • Separate derived products so they can be downloaded individually • Based on user feedback and survey results

  9. SEAN VAUGHN MN.IT at DNR EDUCATION

  11. ENRTF-FUNDED LiDAR TRAINING PROJECT Hands-on workshops presented at GIS labs: Northland Comm. and Tech. College, East Grand Forks Central Lakes College, Brainerd UM-Duluth Cloquet Forestry Center St. Cloud State Univ. UM-Morris UMN St. Paul Campus Mankato State University Winona State University

  12. ENRTF-FUNDED LiDAR TRAINING PROJECT Who attended? • Total attendance = 558 • Unique participants = 226

  13. ENRTF-FUNDED LiDAR TRAINING PROJECT Post-workshop survey: • Evaluate workshops • Assess future needs • Results will be at z.umn.edu/lidar

  14. ENRTF-FUNDED LiDAR TRAINING PROJECT Post-workshop Survey Results: • 74% would join online discussion forum • Additional training needs (most frequent requests): • Advanced hydrologic applications • Using LAS/LAZ/raw data • Preferred training formats: • Half or full day hands-on classroom • Tip sheets • Webinar • Video tips

  15. ENRTF-FUNDED LiDAR TRAINING PROJECT Coming to z.umn.edu/lidar: • Workshop exercises, including • Step-by-step instructions • Practice data sets • Videos of key processes • Workshop lectures, including • Slides • Video • Additional learning resources

  16. ENRTF-FUNDED LiDAR TRAINING PROJECT For more information: • Les Everett, evere003@umn.edu, 612-625-6751 • Ann Lewandowski, alewand@umn.edu, 612-624-6765 • z.umn.edu/lidar

  17. RON WENCL, USGS 3D Elevation Program (3DEP) A National Elevation Program Initiative The National Map

  18. NATIONAL ELEVATION DATASET A Rich History Cartographer Yutaka Hamamoto working on a Wild A-7 stereoplanigraph. USGS, 1968 • Lithographic Section preparing stone blocks used in the printing of topographic maps. • USGS, 1917

  19. LiDAR IMPROVES DATA QUALITY Ten meter resolution Two meter resolution Courtesy of NRCS

  20. NATIONAL ENHANCED ELEVATION ASSESSMENT At a Glance: • Sponsored by the National Digital Elevation Program (NDEP) and funded by USGS, NGA,FEMA, NRCS and NOAA to: • Document national requirements for improved elevation data from technologies such as LiDAR and IfSAR • Estimate the benefits and costs of meeting these requirements • Evaluate multiple national enhanced program scenarios for government consideration • 602 mission-critical activities that require enhanced elevation data were identified by: • 34 Federal agencies and 50 states • A sampling of local governments, tribes, private and not‐for profit organizations • A national program has the potential to generate $1.2 billion to $13 billion in new benefits each year

  21. STATUS OF THE NATION’S ELEVATION DATA NEEA Inventory Results - September 2011 • Map depicts public sources of LiDAR in all states plus IfSAR data in Alaska 1996 - 2011 • 28% coverage - 49 states • 15% coverage – Alaska • 30+ year replacement cycle • Program is well coordinated – less than 10% overlap of coverage • Data quality variable Why is this a problem? • Remaining 72% coverage is 30 or more years old. • Alaska – very poor quality • Meets 10% of reported needs • Current and emerging needs require higher quality data An update will be available in late 2012

  22. DATA QUALITY LEVELS Developed for NEEA study

  23. LiDAR AT THREE QUALITY LEVELS Simulated Quality Levels based on resampled QL1 data 0.35 meter point spacing (QL1) 0.7 meter point spacing (QL2) 1.4 meter point spacing (QL3)

  24. EXAMPLE BUSINESS USES Precision Farming Land Navigation and Safety Geologic Resources and Hazards Mitigation Natural Resource Conservation Infrastructure Management Flood Risk Mitigation

  25. NATIONAL PROGRAM RECOMMENDATION • LiDAR, Quality Level 2 for 49 states, • IfSAR,Quality Level 5 in Alaska • 8 year acquisition • Average Annual Costs: $146 M • Average Annual Benefits: $690 M (B/C: 4.7:1) • Total Possible Benefits Satisfied: 58% Recommended program (QL2) on an 8 year cycle Highest quality level (QL1) on an annual cycle Existing program (QL3) on a 25 year cycle • Needs addressed vary with data quality and replacement cycle

  26. 3D ELEVATION PROGRAM (3DEP) A new initiative to implement the recommendations of the National Enhanced Elevation Assessment (NEEA) • The 3DEP program initiative implements one of the 10 program scenarios resulting from the NEEA study • Key 3DEP goals: • LiDAR data over conterminous United States, Hawaii, territories on 8-year cycle • IfSAR data over Alaska • LiDAR point cloud data to be publically accessible • Multiple derivative products will be supported as services and will be freely available • 3DEP is a program initiative the USGS is developing with a goal to implement an operational program by FY14

  27. PARTNERSHIP STRATEGY IN 3DEP TRANSITION Initial Steps Towards 3DEP Goals: • Shift to higher quality data (QL2) and larger area projects • Cost gap between QL2 and QL3 is narrowing • Emphasis on cost-effective large-area or statewide projects • Share project and funding plans farther in advance to better coordinate and expand interagency data collection • Seek new Federal, State and other partners • Increase coordination and planning with regional and state offices of Federal Agencies • Prioritize Alaska IfSAR in 3DEP data collection plans

  28. 3DEP OUTREACH EFFORTS • USGS Associate Directorand National Geospatial Program Director conducting outreach to NRCS, USACE, DISDI, USGS, FEMA, EPA, USFS, FAA, NGA and NOAA • All understand need for better elevation • Interest in model initiative language and best practices to support transition towards 3DEP • Agency mandates to fund mission/project-specific acquisitions presents a challenge to achieving contiguous coverage • FGDC - Briefings to the Executive Committee, Steering Committee, Coordination Group and National Geospatial Advisory Committee (NGAC); NGAC has established a 3DEP sub-committee • Broader outreach to States, select industries, associations • NEEA website and fact sheets published

  29. BUDGET STRATEGY Expanding 3DEP resources: • Develop increased support from Federal agencies that benefit from 3DEP • NRCS, USACE, DISDI, USGS, NOAA, FEMA, EPA, USFS, FAA, and NGA • Funding mix and expectations will adjust with experience • States / local governments as key funding partners • Continue outreach to develop new 3DEP partners • Facilitate partner participation • Develop new agreements to enable both long-term partnerships and event-driven opportunities • Share best practices to promote 3DEP-compatible data collection within partner and non-partner organizations • Provide model budget language for use by agencies

  30. INTERAGENCY ELEVATION INVENTORY http://www.csc.noaa.gov/inventory/ Ongoing NOAA, USGS, and FEMA collaboration to maintain the inventory and make the data accessible USGS Liaisons currently gathering data for FY12 update Inventory is critical to assessing progress towards 3DEP goals

  31. 3DEP RESOURCES http://nationalmap.gov/3DEP/neea.html • NEEA Report • USGS Fact Sheets • NEEA at a glance • 3D Elevation Program • Resources in work • State information sheets • Journal articles • 3DEP webpage
