Connecting the Dots: Creating AutoCAD Civil 3D Surfaces with LIDAR Data
Technological improvements continue to increase the availability of LIDAR data. However, we have not always had access to the tools necessary for taking advantage of these large data sets. With potentially millions of points, Civil 3D is a tool that can be used to take advantage of LIDAR data for designs. Join Matt Miyamoto for a discussion of some of the issues associated with LIDAR data, and go over the tools available in Civil 3D that allow you to manage your data more efficiently and reduce drawing file size. See how Civil 3D allows us to connect the dots, creating surface models that we can use to develop layouts for master plans, flood boundaries for mapping and drainage analysis, and preliminary site design for permitting and earthwork estimations.
Learn how to:
- add LIDAR Point Files to a surface definition instead of creating Point Objects
- use the Simplify Surface feature to reduce the number of points used in your surface definition
- use Data Clip boundaries to exclude unnecessary points from your surface model
- create a custom Point File Format that includes a sampling variable
- use a database query in Microsoft Access to eliminate intermediate points between surface contours
Who Should Attend
Planners, surveyors, developers, design engineers and others involved in the preliminary design process.
