A primer on Fluvial Hazard Zone Mapping with LiDAR data

The is a very technical post. This is a primer to discuss how LiDAR data is collected, filtered and manipulated to create digital elevation models (DEM) and how those DEMs might be used to identify fluvial geomorphic signatures that indicate where a flood hazard might exist. LiDAR data is commonly used in geomorphic analysis, hydraulic analysis and floodplain mapping. In order to use the data effectively the user needs to understand the limitations of the data.
