Surpac Concepts

Surpac Data Types

Surpac Concepts Overview In this chapter, you will learn about: • •

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

Surpac Data Types Surpac uses many different file types. Each file type is represented by a unique icon in the Navigator. Following is a list of the most common file ty pes used in Surpac: File type

Description

Example

String

pit1.str

A string is a sequence of three-dimensional coordinates representing some physical feature.

DTM

pit1.dtm

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

Geological database

surpac.ddb

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

Survey database

ug_mine.sdb

Survey database (SDB) files are used to connect to relational survey databases. It is 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 means for modelling a 3D body from point and interval data such as drillhole sample data. It provides a method for estimating volume, tonnage, and average grade of a 3D body from sparse drillhole data.

Plot files

pit_str.dwf

The files output from the Plotting module are in DWF format. You can open and edit them in the Surpac plotting window or send them to a plot device such as a Plotter.

Macros

macro.tcl

Macros are custom programs, created to perform a set of repetitive tasks or functionality specific to an operation. You can easily record and edit TCL scripts in Surpac.

Plugins

topo2.dxf

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

Styles file

styles.ssi

Surpac styles files contain information such as drawing styles, colour settings for strings and DTMs, or default Surpac settings.

Function-centric vs Data-centric Operations Many graphical operations in Surpac can be performed quicker via a data-centric approach - by selecting the data first, then specifying an operation to be performed on the data.

Page 10 of 189

Surpac Concepts

Function-centric vs Data-centric Operations

Function-centric When you invoke a function first, and then specify the data you want to use, you are performing a function-centric operation. For example, when you click the icon to Open a file be opened.

, Surpac displays a form. Then you select the file to

You can perform nearly all operations using the function-centric approach. For non-graphical operations, this is often the only option. For example, to calculate volumes between two DTM surfaces, you must use the function-centric approach, such as by selecting Cut and Fill between DTMs from the Volumes menu.

Data-centric When you select data first, and then specify the function to be applied to the data, you are performing a data-centric operation.

Page 11 of 189

Surpac Concepts

Function-centric vs Data-centric Operations

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

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 Surpac can perform on the data.

Strings

String Data Hierarchy

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

String Data Hierarchy Data in a string file is classified into: • • •

Points. Segments. 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 41 of 189

Strings

Types of Strings

Types of Strings There are three types of strings: Open. Closed. Spot Height.

• • •

The table below explains these terms. Surpac Term

Common Term

Example

Open string

Line

Drill hole trace

Closed string

Polygon

Property boundary

Spot height string

Points not associated with a line or polygon

Blast hole collar locations

Description Fields Points, strings, and segments can have one or more pieces of descriptive information associated with them. This information is stored in a description field. Description fields are named according to the order they appear. Description fields are named in the format D, such as D1,D2,D3. For example, a closed segment representing an ore zone could have the gold grade, silver grade, and specific gravity stored in separate description fields. If the information is stored in that order, they could be assigned as follows: D1: gold grade D2: silver grade D3: specific gravity

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

Data Ranges You can use a range to refer to groups of data numbers, such as strings, segments, and points. The comma ( , ) is used for a range whic h includes a start, an end, and optionally an increment. You use 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 separate multiple comma ranges. Here are some examples:

Data values

Spaces in file names are not recommended. In some situations, Surpac may not work correctly when you are using a file that has a space in the fil e 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 Directions When you view closed strings in the XY plane, the points have an order that is either clockwise or anticlockwise. This direction is important when calculating areas and volumes. • •

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

Viewing String Data Here is an example which demonstrates the previous concepts.

o o o

The first line is known as the header record, and contains these items: file name, date modified, purpose (which is empty in this example), styles file. The second line contains the axis record. This is a two-point line used in some sectioning functions. For many string files this is not required; when it is not required, values of zero are used for all coordinates. The Y, X, and Z values of each of the two end points of the axis are stored in the following order: The third line is the start of string data, and is stored as String number, Y, X, Z, D1, D2, D3, … D100 A null record indicates the end of a segment. String 1 is closed, because the first point and the last point are the same. 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: a gold value of 1.23 grams/tonne. a silver value of 14.23 grams/tonne. a specific gravity of 2.7.

2.

Scroll down in the file to see the data shown below.

• • • •

3.


String 8 is open, since the first and last points are different. String 8 consists of two segments. String 30005 is closed, since the first and last points are the same. String 30008 is a spot height string with the survey station name in the D1 field. Exit the editor without saving any changes.

Note: Manually editing string files is not recommended. If the format becomes corrupted, Surpac may not work correctly when using the file.

Attributes and Styles Files

Four viewports with different views of the data are displayed.

Attributes and Styles Files Styles files control how strings, digital terrain models and solid models (DTM files) are displayed. You can change them to suit your needs. With styles files, you can specify many attributes, such as line colour, 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 is next opened, it will automatically use the correct styles.

Task: Change Display Style The dataset in this task represents a soil sampling study that measured arsenic concentrations at various locations. In this task you will change the display style for the points to make it easier to see where the concentrations of arsenic are highest. 1.

Open samp_classified1.str.

Page 52 of 189



This file contains a series of points that show the concentration of arsenic in the soil. The default style settings showing the strings as coloured lines is displayed. Representing the data 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 a separate string.

A point whose arsenic concentration is 350 parts per million (ppm), fo r example, forms part of string 3. In this task, you will display the strings as spot heights to show the areas that have the highest concentration of arsenic. 2. 3.

Click the Legend tab to show the Legend pane. In the Legend pane, click on the “+” sign next to Strings under the file samp_classified.str.

Saving Data

Saving Data There are two ways to save a file: text or binary.

In most cases you will save strings as text files. However, if the text string files are very large (more than 5 MB), it may be worth saving them as binary files to reduce the time it takes to load the data into graphics. Typically, you can expect a saving of up to 15% in the size of the string file and up to 30% in the time to load the data into graphics.

Managing Data in Layers

Layers and the Surpac Work Area

Managing Data in Layers Many computer-aided design (CAD) packages use the term “layer” to define a set of information contained 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. Layers can contain strings from one or more string files. In this sense, you can append data fro m different files into one layer, and create a new file. All layers are contained within the Surpac Work Area (SWA).

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

All layers in the SWA are displayed in the Layers pane, at the lower left corner of t he Surpac window:

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

Triangulated Surfaces

Naming Conventions

Triangulated Surfaces Surpac supports two types of triangulated surfaces: DTM surfaces and three-dimensional solid models (3DMs). A DTM surface is a set of triangles which represent a surface, such as topography or a pit design. A solid model is a set of triangles which represents a three-dimensional shape, such as an ore zone or an underground mine design.

Naming Conventions The objects you create in Surpac are numbered by a system similar to that of string and string segment numbers: String

=>

Object

Segment

=>

Trisolation

Point

=>

Triangle

When you define an object, you explicitly assign it both an object number and a trisolation number. Surpac refers to the object by the object and trisolation number that you assigned. The object number must be an integer in the range of 1 to 32000. The trisolation number must be a positive integer.

DTM Conventions • •

DTMs cannot model overhangs or vertical surfaces. When creating a DTM, strings identified as spot heights are interpreted differently to strings identified as breaklines.

This chapter describes using strings to act as break lines. A breakline string is a string that represents physical features you can see in the real world, such as a crest of a pit, a fault in a geological model, or a contour in a pit. Spot height strings contain random points which, when connected by a string line, do not represent any physical feature. Examples are randomly surveyed points, or borehole collars.

Creating a DTM Surface

Creating a DTM Surface It is important to understand how a string file relates to a DTM. In order for a DTM file to remain valid, the string file from which it was created must remain unchanged from the time that you created the DTM. Therefore, if you modify the string data, you will also need to recreate the DTM.

Page 123 of 189



Creating a Boundary String Between Two DTM Surfaces You will now create a boundary string where a pit intersects the topography. A boundary string file is used for: • • •

delineating cut and fill material for calculating volumes. finding the intersection of a fault plane with a surface. finding where a pit design breaks the natural surface.

There are two methods of creating the boundary string in Surpac: a file-based method and a graphicsbased method. In the file-based method, there is no need to display the DTMs and the boundary string is automatically saved to the nominated file. In the graphics-based method, the DTMs must be displayed in graphics and the boundary string is not automatically saved but is simply displayed in its own graphics layer. You must save your boundary string to a file after it i s generated.

Task: Create a Boundary String - File-based Method Firstly, you will use the file-based method. In this example, you will show only the DTMs for clarity. 1. 2.

Click the Reset graphics icon . Open pit_design1.dtm and topo1.dtm in graphics. Notice that the pit extends past the natural topography. To determine the volume of the pit, you need to define the boundary where the topography cuts the pit design. You do this by creating a boundary string of the intersection between both DTMs.

3.

Choose Surfaces > DTM File functions > Line of intersection between two DTMs.

Page 124 of 189

5.

Drag and drop intersection1.str into graphics. The boundary string is displayed along with the DTMs.

Task: Create a Boundary String - Graphics-based Method You can also complete this process graphically. Using this method, the DTMs must be displayed in graphics because the function uses graphics layers to determine its input and output. 1. 2.

Open topo1.dtm and pit_design1.dtm in graphics. Choose Surfaces > Clip or intersect DTMs > Line of intersection between two DTMs.

Applying a Boundary String

Applying a Boundary String An example of when you might use the Apply boundary string function is when the extents of your data are greater than your survey boundaries. The Apply boundary string function works in the same way as a pastry cutter — it keeps that which is inside a boundary and excludes everything outside. For Surpac to correctly interpret which data is inside or outside a boundary, the boundary string must be a closed string that is clockwise in direction. It is important when using this function to distinguish between spot height strings and strings which represent open or closed features because Surpac treats each one differently. When you apply a boundary string to spot heights, only those points which lie inside or on the boundary are saved. For strings that are not explicitly defined as spot height strings, new points are created where the string intersects the boundary. This is to ensure the strings are neatly clipped to the boundary. In this example, you will use the Apply boundary string function to cut a soil sampling file to a boundary string.

Task: Apply a Boundary String to a Soil Sampling File 1. 2.

Click Reset graphics . Open soil1.str by dragging it into graphics. This file shows soil sampling data over a large area. There are strings that show contours at 100 ppm intervals for arsenic and string 30003 which shows the point locations where the samples were recorded.

3.

Open bdy100.str in graphics. You will use this string to cut the data to a boundary.

The boundary line is in a separate layer to soil1.str. The preceding image gives you a good view of the files that you will be processing with the Apply boundary strings function.

Note: Because this function is a File tools function, you do not have to show the files in graphics for Surpac to process the data. However, by showing the files in graphics, it might help you understand what is happening. 4.

Classifying Strings

Classifying Strings It is often useful to classify the strings in a file, based on the value contained in a specific field. This value may be an elevation, or a numeric attribute, for example an assay grade value. You can classify strings based on the Y, X, Z fields or the description fields D1 to D100. By classifying the data, you will create a separate string, which you can then plot with different attributes such as different colours or line thicknesses. The following example uses the Classify strings by numbers function to classify the file samp1.str based on the value in the D1 field which represents arsenic concentrations in ppm.

Task: Display Soil Samples using String Classification 1. 2. 3.

Open samp1.str which contains soil sample data. Choose Display > Point > Attributes. Enter the information as shown, and then click Apply.

2D Transformations


You will see that the points are coloured according to the classification that you specified.

Note: To see all of the steps performed in this task, run 05e_classify_strings.tcl. You will need to click Apply on any forms presented.

2D Transformations 2D transformations are useful when you have to transform coordinates from one coordinate system to another, for example from the Map Grid of Australia (MGA) system to a local grid. One example of where this can occur is where survey data has been entered using an incorrect backsight. You can then correct the data by transforming the coordinate system onto the backsight that was originally used. Another example is when oblique sections have been taken through a DTM or string file using an axis. In this case, the resultant section string files have coordinates relating to the axis used. You can transform them back to real-world coordinates using the 2D Transformation function. Page 150 of 189

Old points are the coordinates in the mine coordinate system; New points are the coordinates in the national coordinate coo rdinate system. You have entered a Z correction of -750 here because pit2 is 750 meters below pit1.

Verify that the transformation parameters are correct.

If the grids are plane metric grids, the scale factor should be 1.0 . Any variation represents an error. In our example, we have an error of 5 mm in 10 metres.

Note: By default the rotation is displayed in DDD.MMSS format. Shift Y is the difference between Y1 (old) and Y1 (new) as entered on the first form. Shift X is the difference in easting between X1 (old) and X1 (new). In other words, the shifts are the difference in northing and easting between the coordinates of the first point in the two systems. 10.

Polygon Intersection In Surpac, you can use the Intersect polygons function to calculate the area of an ore zone within, or outside of, a pit boundary. This function creates a new closed shape from two existing closed shapes by performing an intersection, outersection, or union operation. Operation

Intersection

Example of Usage

Determining the area which is common to two closed strings. By intersecting intersecting two closed strings you produce a string which has one or more segments which represent the area common to the two strings.

Outersection Determining the the material which might remain after an excavation excavation is completed, for example the excavation of an open pit. Union

Joining two strings together to represent the total area of both strings, for example to represent the shape which will remain after two intersecting pits are excavated.

In the polygon intersection process, one of the closed strings is the intersecting string and the other is the intersected string. In outersection operations, the order in which you specify the strings affects the resultant string.

Task: Intersect Polygons to Calculate the Area of an Ore Body within a Pit Boundary When you know the area of an ore body in a bench you can do other useful calculations, such as an ore volume calculation. 1. 2. 3.

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

Last value if blank Selecting this command causes the field to keep the last value you entered when the application does not supply a value. For example, if you select Last value if blank for the Layer field of the Open File form, the text in the Layer field does not change, but if you select Last value if blank for the Location field, the last file name used is shown. Page 168 of 189


Configuring Windows and Panes in the Interface

Last value Selecting 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 the Open File form, the Layer field displays the 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. Application Selecting this item causes the field to display the value supplied by Surpac. This is the way that Surpac worked in previous versions.

Configuring Windows and Panes in the Interface You can modify panes in the interface using the three buttons on the top right side of t he pane: • • •

Toggle floating. Toggle auto-hide. Close.

Toggle floating The Toggle floating button enables you to “dock” or “undock” the pane. When the pane is docked it is fixed to an area of the Surpac window, when it is undocked it floats so you can move it to any part of the Surpac window. You can also dock the pane by moving it to one of the edges of the screen, or to an existing pane. To restore the pane to its original position, click again on t he Toggle floating button or right-click on the top part of the pane and click Floating.

Toggle auto-hide The Toggle auto-hide button enables you to hide the pane so that you have more workspace for other panes.

Page 169 of 189
