2010 LiDAR Collection in West Virginias Coal Fields WVAGP Meeting December 7, 2010 LiDAR collection specifications Horizontal postings: 1 meter Vertical accuracy: 15 centimeters Additional derived data products include: ESRI elevation grid Hillshade 2 foot contours used in AML program Intensity image useful in QCing LiDAR data ~ 2 TB of data before derived products Slide 2 Initially Contracted LiDAR AoI Slide 3 AoI polygons are watershed rather than county-based. Initial AoI encompassed about 5,000,000 acres or about 33% of the State Project Status as of Nov. 29, 2010 Slide 4 1,322,454 acres 1,162,728 acres Highest priority area of the state was about 3,000,00 acres. 2,485,182 acres have been completed collected. A B Built an ICI ( =isolated computing island ) Isolated three VERY high performance computers from central IT C&C during VERY long compute jobs: No pushes of server OS upgrades followed by the requisite reboots Isolated from any network dependence for software licenses network outages Enough local storage and bandwidth to create more than 8 TB of local storage and a peer-to-peer within-the-room network UPS on each PC still working on this. Slide 5 QCing LiDAR & LiDAR software Slide 6 QCing LiDAR deliverables 2003 Statewide GCPs file Multiple LiDAR datasets that overlap difference grid calculation Trimble R8 GNSS receivers Outsource via FEMA monies a go too Software 64 bit, use multicores Virtual Geomatics 2 floating seats Applied Imagerys Quick Terrain Modeler 1 seat Approval of software purchase still pending 10 months after start of the project no end in site!!! Two Shorted URISA LiDAR Workshop Topics Slide 7 Wide area vs. corridor LiDAR Use of LiDAR intensity data as a substitute for aerial photography LAS Version 1.1 ( dates back to 1.0) LiDAR Intensity Image Slide 8 Produced from spring 2009 flight contracted by the Cabell County Assessors Office two whole LiDAR tiles LiDAR Intensity Image Slide 9 Produced from spring 2009 flight contracted by the Cabell County Assessors Office two whole LiDAR tiles Zoom in from here LiDAR News Headlines The good WVDEP has some more funding for additional LiDAR data deliverables The bad About 50% of our initial AoI remains uncollected 17% of West Virginia The ugly WVUs existing LiDAR hardware and software is supported by Optech for only 1 more year. Slide 10 The end Slide 11 If we dont take a shot at partnering more effectively future opportunities may be lost
