Presentation Transcript

  1. Lidar at the TRCAApplications and Uses for aConservation Authority

  2. Business Units using Lidar • Development Planning and Regulation • Planning Ecology • Enforcement • Archaeology • Research and Climate Programs • Watershed Studies & Strategies • Community Engagement • Property & Land Management • Restoration & Regeneration • Engineering Services • Flood Plain Mapping • Erosion Management • Capital and Special Projects

  3. GIS Portal

  4. Floodplain Mapping • 1D vs 2D modelling • Lidar detects minute changes in elevation • Highly detailed DEMs

  5. Lidar Point Cloud Cross Sections

  6. Point Cloud Cross Sections

  7. Intensity Mapping • Lidar collects x/y/z, rbg, and intensity values • Intensity is the amount of light energy reflected back from surface • Create raster with intensity values • Impervious surfaces (asphalt, concreate, buildings) darker than pervious • Use remote sensing techniques to isolate impervious vs non-impervious • In rural areas drainage features can be detected

  8. Planning and Development • See terrain and detail beneath forest cover • Connect disconnected feature over the landscape • Measure slope and see trends over a site • Demonstrate forest connectivity • Show terrain in 3D and add developments plans
