2007 DSM - Township 45N Range 10E
type: Dataset
description: This dataset has been deprecated. Please use our 2017 Digital Elevation Models instead. The Digital Surface Model (DSM) is a 3-foot pixel resolution raster in GeoTIFF format. This was created using all points (excluding NOISE) from our 2007 LiDAR data without incorporating the breaklines. Merrick and Co. MARS (ver. 8.0.4, build 8185) software was used to create the GeoTIFF images. The DSMs were developed using LiDAR data. LiDAR is an acronym for LIght Detection And Ranging. Light detection and ranging is the science of using a laser to measure distances to specific points. A specially equipped airplane with positioning tools and LiDAR technology was used to measure the distance to the surface of the earth. The classified points were developed using data collected in April to May 2007. The LiDAR points, specialized software, and technology provide the ability to create a high precision three-dimensional digital elevation and/or terrain models (DEM/DTM) as well as digital surface models (DSM). The use of LiDAR significantly reduces the cost for developing this information. The DSMs are intended to correspond to the orthometric heights of the surface of the county including above ground features such as buildings, vegetation cover, utility structures, vehicles ... etc. DSM data are used by county agencies and others to study drainage issues such as flooding and erosion; contour generation; slope and aspect; and hill shade images. Elevation data and models are used in several different ways including: Visualization representations of the elevation data. Examples include: - A hillshaded or shaded relief image - An image representing slope - An image representing aspect Analysis of the elevation data and analytical products which can be generated. Examples include: - Viewshed calculations for visibility and line-of-sight analysis - Areas of highest Solar energy potential - Uses in disaster management - Industrial planning - Calculation of cartographic contours - Calculati…
