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

8. Lidar Point Cloud Cross Sections

9. Point Cloud Cross Sections

10. 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

14. 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
