LiDAR Digital Surface Model.

LiDAR Digital Surface Model, DSM

LiDAR Procesing / 3D Surface Modeling

Client: Hamilton College – Clinton, NY

Techncial POC: Mr David Tewksbury

Project Period of Performance: 11/2009

Technology Employed:

• ESRI ArcGIS ArcView
• ArcGIS 3D Analyst
• ASPRS LAS file format (LASTools)

Project Description Vertex Geospatial created a digital surface model for the Hamilton College campus using LAS LiDAR data collected as part of a larger Oneida County collection in the spring of 2008. The project was a proof of concept effort to assist the department of geosciences with establishing a baseline dataset for use in a class room exercise. LAS tiles were converted to multi-point features using the ArcGIS 3D analyst extension. An ESRI terrain feature dataset was then created from the multi-point data and stored in a file geodatabase. Software from Q-Coherent (LP360) was also used to facilitate viewing and manipulation of the raw LAS tiles.
