iMOD User Manual version 4.4 (html)


6.8IPF Options

iMOD supports several basic functionalities that manipulate IPF-files:


6.8.1IPF Configure

WHY?
IPF-files in iMOD represent point data that can be displayed in different ways.

WHAT?
IPF Configure is used to define the settings for display and assigns a symbol, colour or label to the point data.

HOW?
Select the menu option IPF Configure from the IPF-options menu in the Map menu to display the IPF Configure window. Or, use right-click anywhere on the canvas to open the popup menu. Select the option IPF-options and then choose IPF Configure.

IPF Configure window:

pictures/h4/image333.png

X-Coordinate:

Select the column in the IPF that represents the X coordinate.

Y-Coordinate:

Select the column in the IPF that represents the Y coordinate.

Z-Coordinate:

Select the column in the IPF that represents the Z coordinate. This data column will be used in the Cross-Section Tool and/or 3D Tool.

Sec.Z-Crd.:

Select the column in the IPF that represents the secondary Z coordinate. This data column will be used in the Cross-Section Tool and/or 3D Tool in combination with the Z-Coordinate. In these cases, iMOD will draw a line between the Z-Coordinate and Sec.Z-Crd.. You can use this for the top and the bottom of the screen-depth of a well.

Example:
pictures/h4/image334.png

Scale Column:

Select the column in the IPF to scale the symbol size. This option scales points that have larger values than others, those will be displayed as an increased marker symbol. iMOD will scale the values linearly from large up to small and displays them accordingly, such that small values will be plotted upon large values.

Example:
pictures/h4/highlight.png

Method

Select a method. Select one of the following ones:

  • True Value This scales all points in between a scale size of 1.0 and 5.0 for the true values of the selected Scale Column;

  • Legend As a legend is specified to the IPF file, the minimal and maximal value of the legend is used to scale all points. If values are exceeding the minimal and/or maximal values, the points are discarded;

  • Absolute Value This takes the entries of the selected Scale Column as absolute values to scale the marker;

    Scale Size Value This takes the entries “as-is” of the selected Scale Column to scale the marker.

Visible Depth

Select and specify an interval in meters, over which points are visible.

Single

Select this option to display all points with the same colour.

Pick Colour …

Select this button to display the default Colour window in which a colour can be specified. The current colour is displayed to the right of this button.

Help…

Click this button to start the iMOD Help Functionality (if available in the selected *.PRF file).

Close

Select this button to apply the settings and close the IPF Configure window.

Note: On default, the classes for a legend will be computed linearly between the minimum and maximum values for the selected attribute. Use the options described to adjust this legend in order to plot proper colours.


6.8.2IPF Labels

WHY?
The attributes of point data are displayed as labels.

WHAT?
At the location of each point one or more labels can be displayed.

HOW?
Choose the option Define Labels to be Plotted from the IPF Configure window to display the following window.

Define Labels to be Plotted window:
