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

Lidar Point Cloud Cross Sections

Point Cloud Cross Sections

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

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
