GCD 6 makes it easy to create DEM from point cloud files. This page explains how to use the Data Preparation Menu in GCD to easily create TINs and DEM.
- First use the Raw Point Cloud To Feature Class command from the Survey Preparation Menu in GCD 6 to convert the point cloud into a point shapefile.
- Create an extent polygon using the Create Survey Extent Polygon command from the Survey Preparation Menu in GCD 6. This will be used to better constrain where surveyed points exist and limit the amount of unnecessary interpolation when creating a TIN and/or DEM.
- Once the original point cloud has been converted to a point shapefile and a survey extent polygon has been created they can be used to create a DEM. The video below details how to use the
Point Cloud to TIN and/or DEMcommand from the Survey Preparation Menu in GCD 6 to create a DEM from a point cloud shapefile.
This video tutorial illustrates the application of the
Raw Point Cloud To Feature Classtool to convert a raw MBES point cloud into a point feature class and the application of the
Point Cloud to TIN and/or DEMstool to derive a DEM.
