Data Posting

Use this option to create plots of points from sources such as databases, mapfiles, design and CSV files. You can view multiple data values plotted at one location, with multiple outputs such as underlays, layers, text and spreadsheet files. Data points can be sized or colour-coded based on database values. Values such as horizon thickness, interburdens and partings can be automatically calculated directly from lithological logging.

Instructions

On the Design menu, point to Data Posting.

Open Specification

Specifications file

Select the Data Posting specification file ( .dps ) that you want to open. The drop-down list contains all of the .dps files found in the current working directory. Click Browse to select a file from another location. Once a specification file has been chosen, the parameters contained in the nominated file will be used to populate the Data Posting interface.

To create a new file, enter the file name and file extension. By default, the resulting file will be stored in the current working directory. Use the Browse button to select a different file location.

Audit details

These fields will be automatically populated if the nominated specification file has any modification history. The Created on/by and Last modified on/by fields are 'read-only', i.e. the entries cannot be manually altered by a user.

Databases

Click to define a database. Once selected, the Database source details panel displays.

Database tab

Isis File

Scheme tab

The Scheme tab allows you to nominate the header and interval schemes. The values in the Scheme tab will be populated with the synonyms from the design of the selected database.

Header schema

Select the tables and fields that define the holes to be used. By default, the synonyms from the selected structural database will be used. These values can be changed if desired, i.e. you can use different tables or fields.

Interval schema

Select the tables and fields that define the interval schema that will be used to identify the structure. By default, the synonyms from the selected structural database will be used. These values can be changed if desired, i.e. you can use different tables or fields.

Drillhole Selection tab

Drillholes can either be limited by name or by position. If none of the options within this section are selected, then all available drillholes will be used. Entries within the nominated Drillhole Selection files (.sel), as well as the drop-down lists, may contain wildcards (both * multiple and ? single character).

Models

File Selection

Browse for files using the Browse button, or use the interface showing the available grid files in the current working directory.

Click on the name of the file(s) you want to select. Use the icons to go to the last folder visited, go up one level, or change the way details are viewed in the window.

To highlight multiple files that are adjacent to each other in the list, hold down the Shift key and click the first and last file names in that section of the list.

To highlight multiple non-adjacent files, hold down the Ctrl key while you click the file names.

Move the items to the selection list on the right side of the panel.

• Click the button to move the highlighted items to the selection list on the right.
• Click the button to remove the highlighted items from the selection list on the right.
• Click the button to move all items to the selection list on the right.
• Click the button to remove all items from the selection list on the right.

Wildcard

Enter any characters used as wildcards.  Wildcard characters can be an * as well as regular characters.  

Example:  If the topo_* were used as a wildcard, the result might be topo_area2_aerial, topo_min, or topo_with_pit.

Files of type

Use this to filter the file types that display in the search list.

Selection

Select layout tab

Note:   The resulting text annotations will be assigned group codes of TOP , LEFT , RIGHT and/or BOTTOM. The assigned group code refers to the annotation's position in relation to the data point, for example labels displayed above the point will be assigned a group code of TOP.

Annotation options tab

Annotation options

Check the Rotate annotations check box to rotate the annotations by a given angle. You can either rotate all available annotations or only those annotations that are displayed at a certain position, for example rotate all annotations that are displayed to the left of a point by 10°.

Figure 1 : Rotation Examples

The rotation angles can be entered in decimal degrees or degrees minutes seconds ( ddd.mm.ss ). To do so, select the appropriate angle format button and enter the drafting angle.

For example, to enter a drafting angle of 50°, select the button and enter 50 as the drafting angle. Select a different angle format button to convert a value, for example 50° will become 55.555556 if the button is selected.

Posting Adjustments

This section allows you to adjust the label positions. The labels will be moved away from the posting point, for example to the left or right, by a given distance. You have the ability to enter up to 4 adjustment values.

Post in graphics tab

Underlay

Select this check box to store the posting data in a single underlay. Underlays cannot be saved, i.e. your posting data will be lost once you close the current Vulcan session. Datatip information is available for each of the posted underlay points. To display datatip information, position the mouse cursor over a posted point.

Figure 2 : Datatip Information

Note:   The Display Datatips check box (under the Graphics section of the Tools > Preferences option) needs to be checked in order to display datatips.

To remove the underlay from the screen, select the File > Underlays >Remove Underlay option.

Layer

Select this check box to store the posting data in a nominated layer.

The drop-down list contains the names of all currently loaded layers. If you select an existing layer, then the resulting data will be appended to the nominated layer. If you enter the name of an existing layer that is not currently loaded, then you will need to confirm whether you want to load the layer or replace it, i.e. overwrite its contents.

To create a new layer, enter the layer name. The layer name:

• may contain up to 40 characters.

• must begin with an alphanumeric character [0-9] or [a-z].

• cannot include spaces.

• can include hyphens [ - ], plus signs [ + ], underscores [ _ ], periods/dots [. ].

• can include the special characters of ÁÂÃÀÇÉÊÍÓÔÕÚÜÑ that are used in the Spanish and Portuguese languages.

A layer description can be used to further describe the contents of the layer. A layer description can contain up to 80 alphanumeric characters (spaces are allowed). If a description is not entered, then a default description will be used instead. If the chosen layer already has an assigned description, then this displays when the layer is selected. Existing layer descriptions can be overwritten.

Note:   The resulting text annotations will be assigned group codes of 'TOP , 'LEFT , 'RIGHT and/or 'BOTTOM. The assigned group code refers to the annotation's position in relation to the data point, for example labels displayed above the point will be assigned a group code of 'TOP.

Post to file tab

Check the CSV File check box to store the posting data in a nominated CSV file.

To create a new file, enter the file name and file extension.

Separation character

Select the character that will be used to separate the values in the resulting file. The default separator used is a single comma, but any character can be used. The [TAB] character, which is entered as \T , can also be used to separate the fields.

Insert a header line

Select this check box to place a heading above each column in the resulting file.
