This tutorial gives a brief introduction to several display options for IDF (rasters) and IPF (points) files. See for more detailed references chapter 6 and subsections.
This is what you will do:
• Uploading background image (air photo) and background shape;
• Displaying an IDF-file and manipulate its associated legend;
• Displaying an IPF file and configure its presentation;
• Using the 3D Tool;
• Saving your display configuration.
For this tutorial you need the following files: Airphoto bitmap, shapefile (GEN), iMOD Data Files (IDF), iMOD Point Files (IPF) and TXT-files to which the IPF-files are directing:
• Nederland-West.bmp (and accompanied bmpw file);
• nederland-shapes.gen;
• Formation-KR_TOP.IDF;
• Formation-KR_BOT.IDF;
• Formation-NAWO_TOP.IDF;
• Formation-NAWO_BOT.IDF;
• BOREHOLE.IPF and legend file BOREHOLE.DLF;
• OBSERVATION.IPF;
• Folder BOREHOLE that contains seven folders called SUBSET{i} containing files called B{i}.TXT that represents borehole-logs;
• Folder OBSERVATIONS chat contains files called B{i}.TXT that contains values of the timeseries.
All these files are located in the folder:{installfolder} \TUTORIALS \TUT_MAP_DISPLAY.
Note {installfolder} refers to the full path of the directory you installed iMOD in (e.g. D:\iMOD).
Note If you are a left-handed person and you converted your mouse button settings, ’left mouse button’ should be ’right mouse button’ and vice versa in these tutorials.
1. If iMOD is not yet installed, please follow the instructions as described in section 2.2.
2. Launch iMOD by double click on the{installfolder} \iMOD__V5_1_X64R.exe or
{installfolder} \iMOD__V5_1_X32R.exe in the Windows Explorer.
The IMOD_INIT.PRF is the only file that iMOD needs at the initial startup. If it does not exist, iMOD will create one. The file contains several keywords that are needed by a variety of functionalities in iMOD, however, the keyword USER is the only one that is obligatory. In the coming up tutorial you’ll notice that the content of the IMOD_INIT.PRF file will change. Let us examine the current content.
3. Click on the Preferences button.
This displays the Preferences window. On default the keyword [USER] is selected and the path that is assigned to that keyword is displayed underneath the list box. Probably it shows the folder{installfolder} \IMOD_USER. Several folders will be created in the USER folder. Those folders might be used by iMOD for different purposes, moreover, during your iMOD sessions new folders could be created. However, the most important thing you need to remember about the USER folder is that it stores data created by iMOD, e.g. temporary files, model results and drawings. In this case you might interpret a USER folder as a project folder as well, e.g. USER D: \IMOD \PROJECT_X.
Okay, let us continue with iMOD.
4. Click on the Apply button.
5. Select the option Create a new iMOD Project from the Start iMOD window and click the Start button.
An empty graphical window will appear with default axes and a scale bar. The initial position of the graphical window is (-10,-10) by (10,10). It is possible to turn off the axes and scale bar, so:
6. Go to View and then choose the option Layout and turn the options Show Scalebar and/or Show Axes on and off and observe what is happening.
Show a background images and shapes One of the first things one would like to display is an image of the underlying topography. Let’s do that.
7. Select the option View from the main menu and then select Add Background Image .. from the dropdown menu. This will start the Add Background Image dialog.
8. Select the option Add from the dialog and select the file
{installfolder} \tutorials \TUT_Map_Display\Nederland-West.bmp from the Windows Explorer, see section 5.3 for more information about this dialog.
9. Select the Apply button that closes the dialog.
10. Whenever the image does not appear, click the Show Background Image (
) on the main menu.
Figure 11.15: Example of showing a topographical map.
Besides displaying underlying topography more often background Shape files (polygons or lines) are available. You can think of administrative boundaries (country, state, city) or geohydrological boundaries (rivers, polders, drainage system). iMOD uses the GEN files format for storing shape file information (more on the GEN format in section 9.11). Let’s add a background GEN file.
11. Go to View in the menu bar and select the iMOD Manager (or use the shortcut Ctrl+M).
12. Select the second tab Overlays.
This tab lists all maps used as background only. This can be polygon files (*.GEN) and point files (*.IPF).
13. Click the (
) button to open a GEN file.
14. Select the GEN-file NEDERLAND-SHAPES.GEN and click the button Open.
If the file is not showing up, you might need to change the folder to the appropriate tutorial folder, {installfolder} \tutorials \TUT_MAP_DISPLAY.
15. Click the button (
) and the Line and Symbols window will open (more on Symbols in section 5.7).
16. Click on the Colour … button and select a light red colour.
17. Click on the OK button to close the Colour window.
18. Increase the thickness of the line from 1 to 2 with the arrows near the Thickness field.
19. Click on the Apply button to apply the changes and close the Line and Symbols window.
20. Use the CTRL-left-mouse to select and deselect the NEDERLAND-SHAPES.GEN file in the tab Overlays and click the Redraw button (
) each time the selection is changed.
Figure 11.16: Example of imported and coloured GEN file as Overlay.
An IDF-file stores rasterized data, let us open an IDF-file:
21. Go to View in the menu bar and select the iMOD Manager (or use the shortcut Ctrl+M).
22. Be sure you select the tab Maps
23. Select the Open Map button (
) and select the IDF-file Formation-KR_TOP.IDF and click the button Open. If the file is not showing up, you might need to change the folder to the appropriate tutorial folder,{installfolder} \tutorials \TUT_MAP_DISPLAY.
Observe that the loaded IDF-file emerges in the iMOD Manager. iMOD will not adjust the zoom level automatically to display the entire IDF.
24. Click the zoom button
to zoom to the full extent of the IDF file.
25. Use the zoom buttons on the toolbar (
) to familiarize with their behaviour.
Note: Please remember that a right-click of the mouse button is necessary to stop moving the map around (
).
Figure 11.17: Example of a 2D IDF-view.
Each IDF-file that has been loaded into the iMOD Manager will be displayed by a legend with values that decline linearly between the maximum and minimum values of the IDF-file. A legend is connected to the IDF internally and can be changed easily.
26. Select the Map option from the main menu.
27. Choose the option Current Zoom Level.
28. Choose the option Percentiles.
By selecting the percentile option, iMOD will compute classes for a legend based on the distribution of the IDF values, like a duration curve. Since the option Current Zoom Level has been chosen, the legend will be computed for those values that are inside the current zoom level only.
29. Adjust the legend for the other options (Linear, Percentile and Unique Values) and observe their differences in combination with the options Current Zoom Level and Entire Extent.
30. Click the Legend tab on the iMOD Manager to display the current legend colours and values.
Adjusting a legend like this automatically, is extremely useful whenever the content of an IDF-file needs to be explored. However, legends can be constructed manually and/or loaded from disk.
31. Click the Legend button (
) on the Legend tab of the iMOD Manager to display the Legend window (see section 6.6.1). Make sure you’ve selected the IDF on the Map tab to gain access to this particular Legend tab.
32. Be sure you are on the tab Stretched and deselect the numbered buttons on the left that indicate 2,3,4,5 and6 to turn off their appearance in the colours used by the legend.
33. Click the Apply button and observe the renewed legend ranging linearly from dark brown to cyan (light-blue).
In this way it is easy to change the colour range of the legend.
Figure 11.18: Example of a two-coloured legend.
Let’s use more colours in the legend.
34. Reopen the Legend window (step 31.) and change the dark colour into a red one by clicking on the coloured field. Include more colours in the legend by selecting the buttons that indicate a 2,3,4,5 and/or 6. See the effects for different legends by clicking the Apply button.
iMOD distinguishes two types of legends:
• Stretched: a legend that consists of 255 colours and classes that can be specified for 7 levels only;
• Classes: a legend that consists of maximal 50 classes and colours that can be specified individually.
Reopen the Legend window (step 31.) again and let us create a legend with 10 classes:
35. Click the Classes tab on the Legend window and give in [10] classes in the Class Definition window that appears. Check the optionTake classes as-is and click the Ok button.
36. Each row in the table represents a class. Change the values in the first column (Upper) for each row into [0.0; -5.0; -10.0; -15.0; -20.0; -25.0; -30.0; -35.0; -40.0; -45.0]. Observe that the second column (Lower) will be adjusted automatically, except for row 10. Change the second column for row 10 into [–50.0] to specify the lowermost limit of the legend.
37. The column Label will not be updated automatically, this is the text that will be printed next to the legend.
38. Click the Update Labels button to reflect the entered legend value correctly.
39. Click the Apply button to apply the new legend to the displayed IDF.
Let’s look at another way of adjusting the legend, more convenient actually.
40. Click the Stretched tab to return to the 255 classes legend and then return back to the Classes tab. Give in [10] classes and deselect the option Take classes as-isand click the Apply button.
iMOD will try to adjust the number of classes such that a legend is created with nicely legend classes, automatically. Select the Take classes as-is option whenever you do not want iMOD to create nice, round classes. Or, alternatively when you do want to have more control on the legends, select the option Fixed Interval and specify the interval, minimal and maximal values for the legend classes.
41. Click the Save button (
) to save this legend on disk. Use the Open button (
) to reload the legend (this is not necessary of course).
42. Click the OK button to observe the display of the IDF-file with this adjusted legend.
Let us plot a legend on the map
43. Click the Map option from the main menu, choose the Legend option and then choose Plot Legend on Map.
44. Click the left mouse button near the corner of the legend to change the mouse cursor into a
symbol. Now the legend can be moved to the desired position.
Select the canvas window with your left-mouse button and observe how the cursor changes when the mouse is moved to the boundary of the legend, this grey rectangle is the “legend-box”.
45. Drag around the legend and reshape its size by dragging the boundary of the “legend-box”.
The text size of the legend will be adjusted automatically to fit the boundary box of the legend. Change the width or height of the legend box in case the label text is not readable.
46. Remove the legend by deselecting the Plot Legend on Map option.
Let us open some more IDF-files.
47. Open the IDF-files: Formation-KR_BOT.IDF, Formation-NAWO_TOP.IDF,
Formation-NAWO_BOT.IDF.
48. Select all IDF-files in the Maps tab of the iMOD Manager by dragging the mouse over all files. Or use the combination Ctrl+left mouse button to select the different IDF-files.
Whenever more than one IDF-file is selected in the iMOD Manager the Legend button will become inactive. However, the following method can be used to adjust all legends simultaneously.
49. Click the Map option from the main menu, choose the option Legend and then choose the option Synchronize Legends to display the Synchronize Legends by: window.
50. Select the first IDF (Formation-KR_TOP.IDF) and click the Apply button.
Figure 11.19: Example of the ’Synchronize legend by:’ window.
51. Observe that all IDF-files have identical legends. Select in the iMOD Manager each file sequentially and click the Redraw button (
).
Some of the IDF files show white spots as the current legend does not cover all IDF files properly. You can change a legend also to match all selected IDF files.
52. Select the option Map from the main window, then select Entire Extent and then select Linear.
All IDF files will have a similar legend but the legend classes cover the content of all selected IDF files.
An IPF file stores pointwise information, such as boreholes and/or observation wells. Let us open such a file.
53. Click the Show Background Image (
) on the main menu do deactivate the plotting of the background image.
54. Click the Open Map button (
) and select the file BOREHOLE.IPF.
An IPF file is an iMOD-Point-File and see section 9.7 for more detailed information about the content of these IPF files. The IPF file that we’ve just opened in iMOD does contain the following information:
• X-CRD: X coordinate value of borehole in UTM coordinates;
• Y-CRD: Y coordinate value of borehole in UTM coordinates;
• ID: Identification name for borehole;
• SURFACELEVEL: Altitude of surfacelevel at borehole in m+MSL;
• Z_END: End depth of borehole in m+MSL;
• I_USED: Attribute specifying whether this particular borehole has been used in building the geological model.
Be aware of the fact that all of these attributes do not have any direct meaning in iMOD or whatsoever. In the next steps we will show how these attributes can be used in iMOD.
55. Click the Zoom Full Extent button (
) on the tool bar to adjust the zoom level such that all points are displayed.
All points will be plotted as grey dots initially, however, it is easy to change that.
56. Click the Map option from the main menu, choose IPF-options and then choose IPF Configure to display the IPF Configure window.
iMOD will use the first column of the IPF file (label is X-CRD) for the X coordinate (X-Coordinate:) and the second column (label is Y-CRD) for the Y coordinate (Y-Coordinate:). On default, the Z coordinate will be assigned to the first column, too, which is incorrect.
57. Select the label [SURFACELEVEL] from the dropdown menu at the menu field Z-Coordinate:.
iMOD is able to position points in 3D and/or in cross-sections when this Z-Coordinate: is assigned properly.
58. Select the option Scale Column and select the label [I_USED] in the dropdown menu to the right.
iMOD will increase the symbol to scale each point linearly for values for the chosen label [I_USED]. This feature can be useful to emphasize specific points on a map. The method can varied, we leave it now at [True Value], see section 6.8 for more information on this.
59. Click the Pick Colour button to open the standard Windows Colour window.
60. Select the colour cyan (light-blue) from the Custom Colours field.
61. Click the Ok button.
All points will be coloured as cyan (light-blue) in this manner, however, a legend can be used to colour the points as well based on a selected parameter, so:
62. Select the option Apply to and choose the label [Z_END] in the dropdown menu.
iMOD will create a legend initially, based on the minimum and maximum values of the label [Z_END]. The legend functionalities as described by step 31.-40. can be applied to IPF files too.
63. Click the Colouring and Styles to change the Thickness to [2].
64. Click the Apply button to apply the entered configuration.
65. Click the Close button to close the configuration window.
iMOD colours all points by their values for the label [Z_END] and scale all for values of [I_USED]. Values that are 0.0 got a size of 1.0 and those that are 1.0 got a size of 5.0. If any other values are in between, those will be scaled linear in between.
Figure 11.20: Example of display of points with different scaled markers.
Let us adjust the zoom level such that we enter coordinates that are the centre of the current zoom level.
66. Zoom in onto a particular area by selecting the View option from the main menu and then choose the option Goto XY. Enter the coordinates [111000.0] and [456000.0] for the X- and Y coordinate, respectively.
As we used Zoom (m) as [500.0], the zoom level will have a minimum width and/or height of about 2 x 500 meter. Let us measure that.
67. Click the Measurement tool (
) from the tool bar to measure the distances of the current display. The measured distance can be found at the bottom of the screen in the grey-coloured bar. Break-off with your right mouse button.
The Measurement tool can be used to identify distances between objects on the map, use the left mouse button to include more points during the measuring of the distance.
Since we’ve zoomed in, let us place some labels to the points to see the actual values for [Z_END].
68. Click the Labels button on the IPF Configure window (see step 56.) to open the Define Label to be Plotted window.
69. Select the label [ID] AND [Z_END] from the list.
70. Turn off the option Use different colouring for each field.
71. Select a Textsize of [6].
72. Select the option Use Labelname.
73. Click the OK button to close the Define Label to be Plotted window.
74. Click the Close button to close the IPF Configure window.
Notice that some labels will overlap other labels. iMOD does not support (yet) any advanced labelling to avoid overlapping. Use the zoom functionalities to avoid overlapping.
Figure 11.21: Example of plotted labels using the ’Labels’ button of the IPF Configure window.
Let’s turn off all labeling again and examine our data set in 3-D.
75. Use the combination Ctrl+left mouse button to deselect the labels from the Define Label to be Plotted window (see step 68.). You should select the BOREHOLE.IPF in the iMOD Manager solely to outgrey the IPF Configure option.
77. Click the 3D Tool (
) from the tool bar to enter the 3D environment to observe the boreholes.
By default the colouring used to display the boreholes is different than used in this dataset, so we will load the proper legend file used for displaying the lithology of the boreholes.
78. Click the Load (
) button on the IPF’s tab on the 3D IDF Settings window and select the [BOREHOLES.DLF] from the . \TUT_Map_Display folder.
79. Select the option Place Legend.
80. Maximize the size of the 3D Tool window to a full screen to increase the accuracy of the image.
iMOD will reload the IPF file and displays the boreholes according to the legend read from the DLF file. See section 9.18 for more detailed information about a DLF file.
The 3D Tool is simulated by OpenGL libraries and is very powerful; however, the display of borehole data can take a while to load since all boreholes are stored in individual text files that need to be processed sequentially. The associated IO consumes most of the time.
81. Use your left mouse button to rotate the image and your right mouse button to zoom.
Figure 11.22: Example of a 3D-display of boreholes.
Let us reshape the representation of the boreholes. As you can notice each borehole represents a lithology as displayed in the Legend for Boreholes table. This legend can be created inside and/or outside iMOD; however, the last column expresses the width that will be used to present the corresponding lithology. So, [Clay] is displayed by a smaller width (with=0.25) than [Sand] that has a width of 1.0.
82. Change the width for different lithologies and even change colours by clicking in the appropriate column(s). Click the redraw button (
) to update the 3D image for your inserted changes. For example you might increase the width for Sand to 2.0 to distinguish the difference between clay and sand more.
Figure 11.23: Example of using different thickness’s when displaying lithology of boreholes in 3D.
83. Use the Load (
) button to restore the legend setting to the original values by selecting the . \TUT_Map_Display folder \boreholes.dlf file.
Alternatively we can change the 3D representation of the borehole.
84. Click the option Plot labels, use following colour to add to the boreholes the label selected in theDefine Labels to be plotted window.
85. Select the properties button (
) to start the Define Labels to be plotted window
86. Select the item [ID] from the Select one or more labels.
87. Turn off the checkbox Fancy
88. Click the OK button. Observe what has happened.
89. Check the option Fancy again and see the effects of the options Size, Number of Subdivisions and the option Shade.
Often the number of boreholes is large and therefore we would like to concentrate on those with a particular bore depth. Let us select only those with a penetration depth of more than 30 meter.
90. In 3D Plot Settings in the IPF‘s-tab click the (
) icon to start the 3D IPF settings window.
91. Check the option Hide boreholes with less penetration depth and enter the value of [30].
92. Click the Apply button and observe what happened.
93. Select the Identify tab
94. Select the Map Value button (
) and click on the borehole of interest in the 3D tool window.
The Point Information tab gives an overview of the basic point characteristics of the selected borehole. The Borehole Information tab displays the specific drill information (including Lithology and sand-fraction) for each individual layer. Repeat this procedure for different boreholes by selecting the Map Value button again.
95. Close the Identify session first with a click on your right mouse button. Your pointer should switch to the standard pointer again.
96. Close the 3D Tool by clicking the File option from the main menu and then choose Quit 3D Tool, or alternatively use the close button (
).
Let us combine in 3D the boreholes with the top and bottom IDF’s we’ve loaded into iMOD previously.
97. Select in the iMOD Manager all IDF-files together with the BOREHOLES.IPF and enter the 3D Tool.
You’ll notice that prior to the 3D tool the 3D IDF Settings dialog appears. In this dialog the appearance of the IDF-files can be configured. For example, an IDF can be represented by planes (quads between mids of gridcells giving a smooth surface) and/or cubes (representing the gridcells as flat surfaces, like Lego-blocks). However, any adjustments in this dialog can be made while in the 3D environment as well, so let us accept the dialog as it is.
98. Click the Apply button.
Figure 11.24: Example of 3D image of a set of planes and boreholes; display depends on options chosen in the 3D IDF Settings-window.
You’ll see the graphical representation of the surface for the different IDF’s. Another way to do that is by means of a cross-section (section 11.4). Since the IDF-files represent a clay-body, it is nice to draw them as solids.
99. Click the properties button (
) to change the settings used to display the IDF-files.
Each row defines how that particular IDF will be displayed. To make a solid of two IDF-files you should combine an IDF with another one. The next image shows how the settings should be configured. For example we combined the IDF-file Formation-KR_TOP.IDF (top of the KR-formation) with Formation-KR_BOT.IDF (bottom of the KR-formation) by selecting that file from the dropbox in the third column. Also we changed to Off the Type in the second column of the Formation-KR_BOT.IDF-file. Similarly we adjusted this for the NAWO formation.
Figure 11.25: Example of a 3D IDF Settings window for displaying pairs of IDF’s as solids.
100. Adjust the 3D IDF Settings window as above, keep in mind that your order of files might be different yielding a slightly different configuration.
101. Set the Accuracy: to [Maximal].
102. Click the Apply button.
Figure 11.26: Example of 3D-image of displaying pairs of IDF’s as solids.
103. Activate and deactivate files from the IDF’s tab on the 3D Plot Settings window. Experiment with the options Filled, Wireframes and Filled+Wireframes to see the effects and finally place a legend by checking the Legend checkbox.
104. Experiment with the functionalities on the 3D Plot Settings window. See what you could do with the Plot Original Window options from the Miscellaneous tab.
Another thing that can be done in 3-D is to create our own set of boreholes. This be especially helpful for getting familiar with the geology at a particular spot. Let’s make some “artificial” boreholes.
105. Select the IPFs tab on the 3-D Tool window.
106. Deselect the file “BOREHOLE.IPF” from the Loaded IPFs … list.
It is not necessary to deselect existing IPF files before adding artificial boreholes, however for reasons of illustration it is more clear to turn them off for now.
107. Select the option Edit from the main menu of the 3-D Tool window and select the option Create An Artificial Well.
The following window appears in which you can specify how those artificial wells need to be defined. We will create them manually.
Figure 11.27: Example of the Create An Artificial Well window.
108. Select the option Specify the Location of the Well(s) interactively.
109. Click the OK button
110. Use you mouse to locate any location (red dots) and left-mouse click on the desired location. The dot becomes green. You can repeat this for several locations.
Figure 11.28: Creating artificial well on the 3-D graphical canvas interactively.
111. Apply a right-mouse click to stop adding points.
iMOD will generate a set of boreholes in the commonly known IPF file structure (see section 9.7) and they will be added to the IPFs tab on the 3-D Tool window.
112. Select the IDFs tab in the 3-D Tool window.
113. Select the option Transparancy.
You can see the create boreholes through the geology. iMOD add a colour legend to the boreholes automatically. Pretty nice, isn’t it?
Figure 11.29: Results of the artificial wells.
Okay let’s do something else now.
114. Close the 3D Tool window (see step 96.)
115. Click the Yes button to remove the artificial boreholes created temporarily.
Let us open another IPF file.
116. Open the IPF file [OBSERVATION.IPF] and adjust the zoom level to display all points.
All observation points are displayed by a grey circular dot, however, these points have timeseries associated. Let us look at these associated timeseries.
117. Select the Map option from the main menu, choose IPF-options and then IPF Configure to start the IPF Configure window.
118. Select the option Labels to start the window Define Labels to be plotted.
119. Place a label named ID at each point (see step 68.) by selecting the attribute [ID] from the Select one or more labels from the menu field.
By default any “ \” string will be deleted from the ID field, so the ID-string will shorten whenever it will be displayed on the graphical canvas.
120. Click the OK button to close the Define Labels to be plotted window.
121. Click the Close button to close the IPF Configure window.
Observe the results. You might want to change the number of labels by repeating steps 117. to 119. again.
122. Select the Map option from the main menu, choose IPF-options and then choose the IPF Analyse option to display the IPF Analyse window.
123. Click the option Select For in the dropdown menu when you right click your mouse button on the graphical window (see figure below).
Figure 11.30: Pop-up window with ’Select For’ option when right-clicking on canvas when IPF Analyse window is active.
124. In the IPF Find window, select the label [ID] next to the menu field Attrib.:.
125. Select theUse following character expression radio button and enter the Search String: *B31D011*. Notice that the wildcard is necessary at the first portion of the search string, since all label IDs start with “observation \”.
iMOD finds any point that satisfies this search string. As a result 6 points will be selected and displayed in the table on the IPF Analyse window. Let us display the associated time series.
126. Click the IPF Figure button (
) in the IPF Analyse window to open the IPF Analyse Figure window (see section 6.8 for more information).
Two windows are displayed; Table of Associated Files Content and IPF Analyse Figure. Whenever one time series is selected in the Select one/more to plot list, a table is presented with the actual values for the time series on the Table of Associated Files Content window, let’s do that.
127. Select the file [OBSERVATION\B31D0117001 [OBSERAVATION.IPF] at the list displayed as Select one/more to plot.
Figure 11.31: Example of plotted as figure and table using the button ’IPF Figure’ from the window IPF Analyse.
128. Use the zoom functionalities to analyse the figure in more detail (
).
129. Quit the IPF Analyse Figure window by selecting the option File and then choose Quit.
Let us look at another way of adding/deleting points from the selection table.
130. Move the mouse over the points and observe that the mouse symbol changes to
.
It indicates that when clicking the mouse the particular point will be added to the selection. If the mouse symbol changes to
, it indicates that the particular point will be deleted from the selection.
131. Explore the dropdown menu at your right mouse button to experiment with more options to (de)select points.
Additionally to the display options of timeseries in the IPF Analyse Figure window, let us plot timeseries on the map.
132. Select the Settings tab on the IPF Analyse window and select the option [Simple] from the Graph dropdown menu and click the Apply button.
Figure 11.32: Example of plotted timeseries next to selected points using the option ’Simple’ from the Graph dropdown menu in the Setting tab of IPF Analyse.
For those points in the selection table on the Attributes tab, their associated timeseries will be plotted on the map. Each time another point is added or deleted the display is updated.
133. Use your left mouse button on the map to add and/or delete points from the selection table.
Whenever a small crossed-out rectangle is displayed, it means that the associated timeseries for that point is missing.
134. Click the Close button to stop the IPF Analyse window.
Whenever the IPF Analyse window is closed, timeseries cannot be plotted on the map anymore.
Save /Open a Display Configuration
The entire configuration of legends and settings for the files that are loaded in the iMOD Manager can be saved on disk. Whenever iMOD will be restarted, this file can be loaded to recover the iMOD session again.
135. Click the Save As Current Project button (
) on the tool bar and enter a name for the file, e.g. TUTORIAL1.IMF.
The filename entered will be saved in the {USER} \IMFILES folder on default, however, another location can be entered too. For reasons of efficiency and transferability, it is advisable to store these IMF files in that particular folder.
Let us quit iMOD now.
136. Click the File option from the main menu and choose the option Quit and confirm this action.
