Purpose and Study Area The purpose of this assignment is to use a LiDAR DEM of the Middleton, Nova Scotia, Canada area in order to model flooding. All of the steps in this process including hydrological flattening, hydrological enforcement, watershed delineation and incremental flooding will be discussed. This is completed at various resolutions and compared […]
Overview The chosen study area for this assignment was near Memphis Tennessee including three scenes running North to South along the Mississippi River. The Landsat imagery was downloaded both from libra.developmentseed.org and explorer.usgs.gov/. The images downloaded were on path 23, rows 35 (August 8, 2014), 36 (August 22, 2014) and 37 (August 22, 2014). The […]
LiDAR – Sensor Calibration Using TerraMatch Purpose The purpose of this study is to account for and correct various sensor misalignment issues. There are three types of sensor calibration including rigorous (sensor specific, uses range data), quasi-rigorous (error specific, no range data) and non-rigorous(purely data driven, no trajectory etc). The corrections will be completed by Terramatch […]
