Layer models and cross section.
A layer model is a collection into a layer folder of grids which have the same grid position and resolution. The layer folder is of type Generic and has the Schema Layer model.

Create a layer model. - Create a generic folder and set the schema to Layer Model.
- Copy all time grids into this folder and secure the correct ordering from top to bottom by placing a prefix number 01 02 03 ... etc.
- Perform Zoom to Folder on the time layer model and draw the window frame and axes.
- Display all the layers in random colors.
- Create a map command that display the color using color range from 1000 to 4200.

A layer model consisting of interpretation grids may have grids that go deeper that the next grid in sequence. We then have to check the layer model and if necessary do truncation.

Check and truncate the layer model. - Visualize the layers one by one to see if there is any overlap.
- Activate upon the layer model the command Check and truncate layers from top and downwards.
- We run on defaults; therefore click on Execute to perform truncation from top and downwards.

Having a layer model it is convenient to make cross sections.

Create cross sections. - Highlight layer model folder and read the command Information about the layer model.
- Activate the command Initialize the layer model into Workspace. The layer model grids are read into workspace for fast retrieval.
| Info |
|---|
| - When the layer model grids are in workspace it is quick to perform cross sections and other calculation.
- If a another layer model shall be studied just activate Initialize the layer model into Workspace on the new layer model.
- Cross sections will be performed on the layer models grids in workspace.
|
- Create a new Generic folder and give it the name Cross sections and set the schema to Cross sections. Cross section commands will now be visible on this folder.
- Perform on the cross section folder Display fence type cross section. It will display and the fence data is saved in the cross section folder.
- Erase the screen and open the cross section folder perform on the fence data Vertical redisplay from cross section data.
- Perform on the cross section folder Cross section color table.

If you want to correct or reinterpret some parts of the interpreted lines they have to be imported into Geocaps interpretation systems; see Importing Interpretation and Seismic Interpretation.Not all seismic 2D sections are in the course project, but they are present in the Tutorial data1 which can be downloaded.
