Posted by Jerry Knisley, Last modified byon 23 August 2016 11:02 AM
For a straight comparison between your survey surface and the channel file. TIN MODEL requires only the channel file or a 3D planned line file with the Input data file in the initial setup dialog.
Note: If you want to see this comparison itemized by section, you must include a planned line file.
Building the TIN Model for Standard TIN-to-Channel Volumes
In the Volume Calculations Dialog:
Sample TIN-to-Channel Settings
1. Select ‘TIN to Channel’.
2. Set your report options.
3. Click [Calculate].
Beware! Use caution when computing volumes where the survey lines are not perpendicular to your side slope. Because of the way TIN Models are created, your volumes may be overstated. We are working on ways to improve on this, but nothing will be perfect.
Beware! With so many different options that can affect your outcome It requires some careful checking to ensure you are classifying the material as either accumulated or depleted. Such options include:
• XYZ Files are in Depth or Elevation
• Initial File survey came before or after the Additional File survey
