  1. Availability of LiDAR data in Washington State LiDAR Workshop January 3rd 2008 Terry Curtis, C.P. Photogrammetry Supervisor Wash. Dept. of Natural Resources

  2. DNR - Land Management and Regulation5 Million acres of Trust Lands

  3. LiDAR data is NOT “Imagery” It’s just a bunch of elevation POINTS…… Some LiDAR Misconceptions

  4. LiDAR data is NOT “perfect”… Vegetation is the enemy

  5. LiDAR does NOT replace Aerial Photography Aerial photography contains true SPECTRAL information and actual IMAGERY, and should be used in conjunction with LiDAR.

  6. LiDAR Compare

  7. Aerial Compare

  8. LiDAR data isn’t “FREE” Yes, there is some Publicly available or Public Domain data SOMEONE had to pay for it initially LiDAR is EXPENSIVE !!

  9. Counties Federal Agencies (USGS, NOAA) Other Public Agencies Private Companies (good luck!) Puget Sound LiDAR Consortium (PSLC) WHERE can I obtain existing LiDAR data ??

  10. PSLC Webpage

  11. History of LiDAR in PNW 1996 > Present

  12. HISTORY MAP

  13. Current BASIC data specifications

  14. PSLC Status Map

  15. Status Comparison

  16. USGS/DNR Skagit/Whatcom Project DNR Forest Inventory Blocks San Juan County Spokane County/Avista Known NON-PSLC Data Available, Planned, or In Progress

  17. Skagit Whatcom

  18. DNR - Image Tree

  19. San Juan Proposed

  20. Issue your own RFP for LiDAR acquisition Look for PARTNERS to reduce costs Economy of scale - larger area = lower unit cost PLAN AHEAD - a MINIMUM of one full year Few local vendors or vendors with WA experience Be wary of low-cost proposals Can use PSLC/Kitsap County CONTRACT Established specs and pricing They do the contract admin and QA/QC Proven track record - knowledgeable scientists and staff What if no LiDAR data exists for my project ?

  21. Where Can I learn about…

  22. ASPRS-Portland

  23. Top Surface

  24. Bare Earth

  25. Aerial
