WV DEP Coal LIDAR Project Update (3 Nov 2011)

  1. 1. West Virginia’s Coal Fields LiDAR Project Update WVAGP Meeting November 3, 2011
  2. 2. NRAC’s Last Project Status Map for WVDEP Slide 2
  3. 3. Statewide LiDAR Delivered So Far Frist deliverable has been QC checked by FEMA’s LiDAR QC Contractor Dewberry successfully Slide 3
  4. 4. LiDAR Coverage, by CountyTable above listscoal field countieswith 100%coverage as aresult of WVDEP’sLiDAR flights (theexception isMarion which flewtheir own missionbut shared thedata with WVDEPvia WVU NRAC).Table top right counties shows additional counties with zero to partial LiDAR coverage as of Autumn 2011 asa result of WVDEP’s LiDAR work. Each county lists its corresponding percentage of total coverage.Additional counties confirmed to have county wide LiDAR are Cabell, Jefferson, Kanawha and Raleigh withnew county-wide coverage in 2011. There may be more in the northern or eastern panhandles. Slide 4
  5. 5. Spatial Extent  by watershed not county Slide 5
  6. 6. First Derived Dataset Slide 6
  7. 7. Second Derived Dataset Slide 7
  8. 8. Third Derived Dataset Slide 8
  9. 9. Resolution and Change Comparison WVDEP 2009 Data At this scale, differences in data resolution and change over time are not widely noticeable. However, uponfurther analysis, significant differences in resolution and change become evident, as shown in the next slide…WVSAMP 2003 Data Slide 9
  10. 10. Resolution and Change Comparison The image above isWVDEP 2009 Data a portion of the most recent LiDAR flown by West Virginia University (WVU) for WV Department of Environmental Protection (WVDEP). The image below is a portion of the data Change in Landscape provided by the West Virginia Statewide Addressing and Mapping Project Change in Resolution (WVSAMP). Both examples are from the same region in Boone County, West Virginia. Changes to the landscape that have occurred since the date of data collection by WVSAMP versus the date of collection from the WVDEP LiDAR are clearly visible. This comparison also shows the considerableWVSAMP 2003 improvement in Data resolution between the two datasets. Slide 10
  11. 11. Hillshade of a Mining Site, Wyoming County, WV Slide 11
  12. 12. 5’ Contours Overlaid on Hillshade Slide 12
  13. 13. 5’ Contours of the Mining Site Slide 13
  14. 14. LiDAR, Blair Mountain, and Viewshed Analysis WVDEP’s first official use of this LiDAR data was a viewshed analysis investigating existing and proposed mining permits around Blair Mountain. Slide 14
  15. 15. LiDAR, Blair Mountain, and Viewshed Analysis Slide 15
