  1. THE CITY OF BRANSON GISLIDAR BEGINNINGS ADVANCED LIDAR WORKSHOP March 15, 2012 Curtis Copeland G.I.S. Coordinator City of Branson

  2. LIDAR ACQUISITION at BRANSON • Orthophotography and Digital 2’ Contour Mapping • Prior to 2011 – Traditional Photogrammetric DTM Development • Airborne GPS and Ground Control • ASPRS and NMAS • DTM to support 100 - 50 Scale Mapping of Plan and Topo • Support 6” Pixel Orthophotography • Quality Control – Bridges, Extreme Terrain/Cliffs • 2011 – New Technologies, New Standards and Specifications

  3. IMPORTANT TERRAIN-BASED PROJECTS at the City of BRANSON • Slope • Branson is an area with a lot of topographic relief, this creates a number of challenges • Structure and Site Development • Infrastructure Design • Sewer and Water • Roads and Bridges

  4. Special Cases • Sidewalks • Accessibility • Roads • Slope Thresholds • Addressing (Little or No Grid System) • How has SLOPE been Geoprocessed and Analyzed?

  5. Drainage • Again, the great amount of topographic relief in the area creates challenges in handling drainage and storm water • The urbanized areas of Branson have extensive amounts of hard/impermeable surfaces. • Coupled with steep terrain, drainage calculations and storm water design are complicated • Protecting area waterways is a high priority.

  6. Flood Risk Management • Branson suffered significant flooding in 2008 and 2011 • Evacuation Planning and Recovery • Branson GIS data was utilized by multiple agencies before, during, and after the floods • Tree Canopy and Forested Area Management • Tree conservation is an important topic for the City of Branson

  7. LIDAR PROJECT WISH-LIST for Branson GIS • Slope Analysis • Hard/Impermeable Surface Analysis • Building and Structure extraction • Tree Canopy and forest area calculations

  8. APPLIED LIDARLEAP-DAY 2012 TORNADO in Branson • Viewing Before-After Ortho Imagery draped on Terrain in ArcGlobe • Damage Assessment and Measurement Utilizing Oblique Imagery

  9. Thank You! Curtis Copeland G.I.S. Coordinator City of Branson 417-337-8540 ccopeland@bransonmo.gov
