Create Grid from Section Line

Use the Create a Grid from a Section Line dialog (GRIDSECTION GX) to create a grid from section data stored in a single line.

Create a Grid from a Section Line dialog options

Output grid

Name of the file to write the TIN information to. This is a binary file and cannot be read using a text editor program. The saved file can then be used as input to other GXs, such as TINMESH.

Script Parameter: TINDB.FILE

X (along ground) channel

 

The position along the section. Usually the X or Y channel.

Script Parameter: GRIDSECTION.X (Default X)

Z (elevation) channel

 

The elevation of the point in the section. Usually the Z channel.

Script Parameter: GRIDSECTION.X (Default Z)

Grid value channel

 

The channel containing values to grid.

Script Parameter: GRIDSECTION.GRIDVAL

Grid cell size

The output grid cell size. The output grid is created to cover the full range of the input data.

Script Parameter: GRIDSECTION.CELLSIZE

Section information can be stored to a line. For instance, the line can contain X, Y and Z values, with either the X or Y values held constant and the Z values indicating the elevation of the position in the section. The method creates a Triangular Irregular Network (TIN) of the points, then uses the TIN Nearest Neighbour Algorithm to calculate the values at the grid nodes.

The current displayed line is used.
