SurpacConcepts Exercises

Surpac Concepts

OverviewIn this chapter, you will learn about:

l Surpac data types.l Function-centric vs data-centric operations.

Surpac Data TypesSurpac uses many different file types. Each file type is represented by a unique icon in the Navigator.Following is a list of themost common file types used in Surpac:

File type Example Description

String pit1.strA string is a sequence of three-dimensional coordinates representing somephysical feature.

DTM pit1.dtm

Digital Terrain Model (DTM) files are generated from .str files and can representsurfaces or solids. A DTM surface is a set of triangles that represent a surfacesuch as topography or a pit design. A solid model is a set of triangles thatrepresents a 3D shape, such as an ore zone or an underground mine design.

Geologicaldatabase surpac.ddb

Drillhole database (DDB) files are used to connect to relational drillholedatabases. It is a text file that tells Surpac which tables and fields to read fromthe database.

Surveydatabase ug_mine.sdb

Survey database (SDB) files are used to connect to relational survey databases. Itis a text file that tells Surpac which tables and fields to read from the database.

Block model block.mdl

A Block Model is a form of spatially-referenced database that provides a meansfor modelling a 3D body from point and interval data such as drillhole sampledata. It provides a method for estimating volume, tonnage, and average grade ofa 3D body from sparse drillhole data.

Plot files pit_str.dwfThe files output from the Plotting module are in DWF format. You can open andedit them in the Surpac plotting window or send them to a plot device such as aPlotter.

Macros macro.tclMacros are custom programs, created to perform a set of repetitive tasks orfunctionality specific to an operation. You can easily record and edit TCL scriptsin Surpac.

Plugins topo2.dxfThis icon identifies a type of file that you can import directly into Surpac. Forexample, you can import any file that has one of the following extensions: .dxf,.dwg,.dgn,.dm,.shp,.dgd.

Styles file styles.ssiSurpac styles files contain information such as drawing styles, colour settings forstrings and DTMs, or default Surpac settings.

™ Page 22 of 237

SurpacConcepts Function-centric

Function-centric vs Data-centric OperationsMany graphical operations in Surpac can be performed more quickly via a data-centric approach - byselecting the data first, then specifying an operation to be performed on the data.

Function-centricWhen you invoke a function first, and then specify the data you want to use, you are performing afunction centric operation.

For example, when you click the icon to Open a file , Surpac displays a form. Then you select thefile to be opened.

You can perform nearly all operations using the function-centric approach. For non-graphicaloperations, this is often the only option.

For example, to calculate volumes between two DTM surfaces, you must use the function-centricapproach, such as by selecting Cut and Fill between DTMs from the Volumesmenu.

Data-centricWhen you select data first, and then specify the function to be applied to the data, you areperforming a data centric operation.

For example, when you right-click a file, a popup menu is displayed. You then choose the operationto be performed – such as Open.

™ Page 23 of 237

SurpacConcepts Questions

Many graphical operations are quicker and easier to perform using the data-centric approach.

For example, you can select data in a string file, and then right-click to display functions that Surpaccan perform on the data.

Advanced InterfaceOperations Activity: Run Two Functions from the Function Chooser

Using the Function ChooserA quick way for you to run a function is to use the function chooser. You can type an “alias” into thefunction chooser to run a function. An alias is an abbreviation of the function name.

Activity: Run Two Functions from the Function Chooser

1. Drag and drop pit_design1.str into graphics.2. Type CS (for Clear Screen) into the function chooser.

Note: The function chooser field is located in the lower part of the Surpac window.

3. Press ENTER to run the function.Running the Clear Screen function makes the graphics area empty but, unlike the Resetgraphics function, it leaves the data in the layer.

4. Type the alias DRWS (for Draw Strings) into the function chooser.5. Enter the information as shown, and then click Apply.

survey1665.str is displayed in graphics.

Note: You can find a complete list of aliases in the files SSI_ETC:short.ssi and SSI_ETC:Surpac.mst.

Working with FormsYou control how a function works by entering parameters into a form. The terms form is a type ofdialogue box and these terms can be used interchangably.

TheOpen File form and its components is a typical form.

™ Page 47 of 237


By clicking once to highlight a field on a form, and then right clicking, you see options to help you fillin the form.

™ Page 48 of 237


Last value if blankSelecting this command causes the field to keep the last value you entered when the applicationdoes not supply a value. For example, if you select Last value if blank for the Layer field of theOpenFile form, the text in the Layer field does not change, but if you select Last value if blank for theLocation field, the last file name used is shown.

Last valueSelecting this item causes the field to keep the last value regardless of the value that Surpac inserts.For example, if you select Last value in the Layer field of theOpen File form, the Layer field displaysthe name of the layer that you used on the last occasion you used this form.

Constant..Selecting this item allows you to enter a value to use for this field every time you use the form.

ApplicationSelecting this item causes the field to display the value supplied by Surpac. This is the way thatSurpac worked in previous versions.

Configuring Windows and Panes in the InterfaceYou can modify panes in the interface using the three buttons on the top right side of the pane:

l Toggle floating.l Toggle auto-hide.l Close.

Toggle floatingThe Toggle floating button enables you to "dock" or "undock" the pane. When the pane is docked itis fixed to an area of the Surpac window. When it is undocked it floats so you can move it to any partof the Surpac window. You can also dock the pane by moving it to one of the edges of the screen, orto an existing pane.

To restore the pane to its original position, click again on the Toggle floating button or right-click onthe top part of the pane and click Floating.

Toggle auto-hideThe Toggle auto-hide button enables you to hide the pane so that you havemore workspace forother panes.

Managing Data in Layers Activity: Create Layers

Managing Data in LayersMany computer-aided design (CAD) packages use the term “layer” to define a set of informationcontained within one file. In this sense, a Surpac string number is the same as a CAD package “layer”.However, in Surpac, a layer is an area in memory which contains data displayed in graphics. Layerscan contain strings from one or more string files. In this sense, you can append data from differentfiles into one layer, and create a new file. All layers are contained within the SurpacWork Area (SWA).

Layers and the Surpac Work AreaWhen Surpac starts, it creates an area in memory called the SurpacWork Area (SWA). All data that isdisplayed in graphics is stored within one or more layers, which are located within the SWA. Beforeyou have displayed any data in graphics, the SWA contains one layer, called the “main graphicslayer”.

All layers in the SWA are displayed in the Layers pane, at the lower left corner of the Surpac window,these display as shown below.

Creating LayersBy dragging a file from the Navigator to graphics, you create a new layer with the same name as thefile. You can also create a new layer using theNew button on the Layer pane.

Activity: Create Layers

1. Click the Reset graphics icon .2. Drag and drop pit1.str into graphics.

Strings Exercises

StringsThemost common file format used for storing information in Surpac is a string file. A string filecontains coordinate information for one or more points, as well as optional descriptive informationfor each point. It is important to understand how Surpac organises and uses data stored within astring file; this will enable you to work more efficiently with strings.

String Data HierarchyData in a string file is classified into:

l Points.l Segments.l Strings.

All points in a string file are grouped into segments, which are further grouped into strings.

The example below shows conceptually how a string file contains strings, which contain segments,which contain points.

™ Page 89 of 237

Strings Exercises

Types of StringsThere are three types of strings:

l Open.l Closed.l Spot Height.

Surpac Term Common Term ExampleOpen string Line Drill hole traceClosed string Polygon Property boundary

Spot height stringPoints not associated with a line orpolygon

Blast hole collar locations

Description FieldsPoints, strings, and segments can have one or more pieces of descriptive information associatedwith them. This information is stored in a description field. Description fields are named according tothe order they appear. Description fields are named in the format D, such asD1,D2,D3.

For example, a closed segment representing an ore zone could have the gold grade, silver grade, andspecific gravity stored in separate description fields. If the information is stored in that order, theycould be assigned as follows:

D1: gold grade

D2: silver grade

D3: specific gravity

Data NumberingStrings, segments, and points are identified by unique numbers. You can assign string numbers torepresent particular features, such as string 1 for toes in a pit, string 2 for crests, and string 99 forspot heights. Surpac automatically assigns segment numbers and point numbers.

Data RangesYou can use a range to refer to groups of data numbers, such as strings, segments, and points.

The comma ( , ) is used for a range which includes a start, an end, and optionally an increment. Youuse the following format to specify such a range in Surpac:

,,

Note: When the increment is 1, you can use ,without specifying the increment.

The semicolon ( ; ) is used to identify unique values, or to separatemultiple comma ranges.

String File NamesSurpac string file names have the following components:

Component Description Required?Location Any combination of characters and numbers RequiredID Numbers only OptionalExtension Always .str Required

Here are some examples of file names:

Filename Location ID Extensionpit.str pit .strbench105.str bench 105 .str2007design.str 2007design .str2007design2.str 2007design 2 .strgrade_control135.str grade_control 135 .strdhcomp2_50.str dhcomp2_ 50 .strlevel-300.str level -300 .str

Spaces in file names are not recommended. In some situations, Surpac may not work correctly whenyou are using a file that has a space in the file name.

You can use ranges to refer to the ID of filenames. For example, you can refer to the files:

geo130.str, geo140.str, geo150.str, geo160.str, geo170.str

using the following syntax:

Location: geoID: 130,170,10

String DirectionsWhen you view closed strings in the XY plane, the points have an order that is either clockwise oranticlockwise. This direction is important when calculating areas and volumes.

l Clockwise strings represent an area of inclusion.l Anticlockwise strings represent an area of exclusion.

Activity: View String Data in a Text Editor

1. From the Navigator, right click bench105.str, and then select Edit.The file opens in your text editor.

l The first line is known as the header record, and contains these items: filename, datemodified, purpose (which is empty in this example), styles file.

l The second line contains the axis record, This is a two-point line used insome sectioning functions. For many string files this is not required; when itis not required, values of zero are used for all coordinates. The Y, X, and Zvalues of each of the two end points of the axis are stored in the followingorder:

l The third line is the start of string data, and is stored as String number, Y, X,Z, D1, D2, D3, … D100.

l A null record indicates the end of a segment.l String 1 is closed, because the first point and the last point are the same.l When the file was created, the following values were chosen: D1 = gold (g/t),

D2 = silver (g/t), and D3 = SG. String 1 outlines an area of low grade ore with:l a gold value of 1.23 grams/tonne.l a silver value of 14.23 grams/tonne.l a specific gravity of 2.7.

Viewing and Saving Data Activity: Change DisplayStyle

Viewing and Saving Data

Attributes and Styles FilesStyles files control how strings, digital terrain models and solid models (DTM files) are displayed. Youcan change them to suit your needs. With styles files, you can specify many attributes, such as linecolour, marker size and drawing method (lines, markers, attributes, values).

Every time you save a string file, the associated styles file is also saved so that when the string file isnext opened, it will automatically use the correct styles.

Activity: Change Display StyleThe dataset in this task represents a soil sampling study that measured arsenic concentrations atvarious locations. In this task you will change the display style for the points to make it easier to seewhere the concentrations of arsenic are highest.

1. Open the file samp_classified1.str.This file contains a series of points that show the concentration of arsenic in the soil. Thedefault style settings showing the strings as coloured lines is displayed. Representing thedata in this way does not help you to see where the arsenic concentration is high or low.

The points have been classified into four levels of concentration, each represented by aseparate string.

™ Page 98 of 237


A point whose arsenic concentration is 350 parts per million (ppm), for example, formspart of string 3.

In this task, you will display the strings as spot heights to show the areas that have thehighest concentration of arsenic.

2. Click the Legend tab to show the Legend pane.3. In the Legend pane, click on the "+" sign next to Strings under the file samp_clas-

sified.str.The legend shows that string 1 is black, string 2 is blue, string 3 is blue-green, and string 4is green.
