Terramodel 10.13 TML List

Compute points offset from a selected alignment.

Create a set in the current layer connecting points offset from an alignment. The default horizontal and vertical offsets may be set to non-zero values.

The point elevations are computed from a vertical profile with the same name as the horizontal alignment, if it exists.

Filter superfluous points from a DTM.

This is useful for filtering point clouds generated by laser scanners such as Callidus, Cyrax and I-SiTE, and other large DTMs, where much of the data is not significant.

Recolours points on spikes, points on similar grade and points where removal would make insignificant changes to the volume.

These points are marked so they are no longer in the DTM. See GC53 for control of this attribute.

To reduce the size of the DTM, select these points by the changed colour and delete.

See also FILTER to reduce vertices along a pline, BLFILTER to reduce points along a breakline set. GC31 removes duplicate points. GCGEOCODE is a separate application, which can quickly filter of DTM points not close to the average surface model.

Create and edit aliases used by Terramodel.

Use this to call functions from command line, icon or workspace by different names.

ALIAS edits the alias file, so you can add or modify the command list. You can also use a text editor.

The alias file can be nominated in TMODWIN.INI, otherwise Terramodel uses the first ALIAS.INI in the Terramodel Search Path (TSP), and failing that the ALIAS.INI in the Locale subfolder for the default for the installed language. You can make your own for a local language, dialect, idiom or standard.

ALIAS allows you to enter a familiar command for different software, and have Terramodel execute the equivalent. For example, typing z or w at the command line may execute Zoom.

In another example, Geocomp users often enter 17 to find the 3D vector between points. In the Geocomp release, 17=gc29 in the alias file means entering 17 will execute GC29 for a similar result.

Some commands have arguments. For example, zo=magnify 0.5 zooms out or you could make a toolbox with eight directional buttons calling aliases such as vpanleft=VPAN 7 1.

Use EXEC to execute an external command (with optional parameters). For example, GST. The maximum argument in an alias is 66 characters. If you need to exceed this, see RUN.

An alias takes precedence over a command with the same name. This lets you redirect attempts to use a command to some other preferred equivalent. See for example F8T and GC3PTARC. You can't alias to an alias, but you can copy the command and arguments using ALIAS.

Import the vertices of alignments from an ASCII text file.

These alignments can be HAL, VAL or SLOPE alignments. You can include the radii for horizontal curves or vertical curve lengths for profile and slope profiles. It can also adjust the profiles for a baseline with chainage equations.

The current view determines whether you get a HAL (for PLAN) or VAL (for PROFILE) or SLOPE (for SUPER).

Browse or enter the filename.

The Settings button controls the Name, Color, and Linetype for the alignment created.

The check box "Adjust for HAL Equations", allows you to select the registered HAL from which to extract chainage equations.

The ASCII file is typically exported from a spreadsheet.

Create breaklines along the arc segments of all sets on a designated DTM layer.

Create points at regular intervals along the arc and connect a set from the existing first TP to each of the new points and finally to the end TP of the arc. The number of chords created is based on a specified maximum middle ordinate value which indicates the maximum allowable deviation from the true arc that each Breaklines chord may produce. The actual deviation will be less than or equal to this value.

The elevation of each point is interpolated along the arc from the elevations of the points at the arc TPs. If either TP has an undefined elevation, Breaklines will not be formed along that arc, and a warning message will be issued in the message area.

The new sets are named SETARCBL so they can be selected separately from the arcs.

Create an elevation view of points.

Copy selected points into an "Elevation" drawing in View 6.

The position of the point along the selected Baseline determines the horizontal position in View 6, while the Z coordinate of the Point determines the vertical position in View 6.

The points in View 6 are placed on the same layer that the points were originally placed on in the Plan View.

The points in View 6 are given an alphanumeric identifier (point number). If the baseline has a Name, then this name and the original identifier are combined to create the identifier for the point in View 6. If the baseline does not have a name, a (2) is combined with the original identifier to create the identifier for the point in View 6.

Max Alpha Points must be set in SYSTEM to a large enough number.

S

Recentre views based on chainage.

Ideal for working along a long narrow alignment such as a road, rail or pipe.

For any selected roadjob, nominate a chainage by selecting a location in the plan, profile, super or xsect views. The plan, profile and super views, if open, are recentred on the horizontal or vertical alignment at the selected chainage. The active chainage is set to the nearest cross section, and the Xsect view is fitted to the data.

If the selected view is the Xsect, the active chainage is used, if set.

The match button uses the centre of the active plan, profile or super view to recentre the other views. If the profile view is active, the plan and super views are scaled to fit the chainage range.

There are buttons to zoom in or out by 25%, to fit data in all four views, and to move to the next or previous chainage then making it active.

On starting this option, the views are horizontally tiled.

Compute superelevation from existing crossfall.

For every point in a centreline set, compute the crossfall perpendicular to the HAL from the centreline to left and right edge-of-road sets. These crossfalls are placed in the Super view on the current layer so you can design to match existing superelevation.

Xlines are ignored as these are not interpolated linearly.

Note that the changes are processed in dictionary file order, so be careful. If, in the example, 'CH' replaced was before 'CHAINAGE', you would get 'PKAINAGE', not 'PK'.

If the new text is a different length, you can match the text width attributes to suit.

You can also refer to characters by their three-digit decimal ASCII value. For example, \010 for new line and \176 for degree sign. What you see depends on the font. Not all fonts contain all characters. For example, in some fonts degree sign is \127. In fonts such as symbol.fnt, you can specify a symbol by this method.

Convert sets to plines or plines to sets.

Any combination of sets and polylines can be converted to a single type of object. New lines are assigned the color and linetype of the original line and placed on the layer of the original. Names, station values, and other attributes are not retained. You have the choice of keeping or deleting the original objects.

Convert Options
Lines	This select control is used to select the lines to be converted
To (Set or Pline)	These radio buttons are used to select the type of lines to be created
Del old	This check box is used to optionally delete the original lines
Dup pts ok	This check box lets Terramodel create points for new sets that have duplicate northings and eastings (point numbers cannot be duplicated)
Lay	This check box lets you set up the default behavior for placing the new entity on a layer. When this box is checked, Terramodel places new entities on the current layer. When this check box is not checked, Terramodel places new entities on the same layers as the original objects.
Tips on using Convert
Dup pts ok	CONVERT takes a long time to convert a lot of plines to sets, if "Dup pts ok" is OFF. It is much faster to CONVERT with this ON, then use DTM formation or GC31 to remove duplicate points afterwards.
Specific purposes	Terramodel uses sets and plines for specific purposes. Some types of curves and arcs cannot be represented by the other type. See the Terramodel User Guide for more information about object types.
Visibility	When converting sets to polylines the visibility of hidden set segments is honored. To view all hidden set segments use the DISPLAYSET command. To hide set segments use the HIDE command.
Arcs	When converting a polyline to a set line, a new point object is created for the radius point and at each PC and PT. If multiple arcs use the same arc points, duplicate points will be created at each arc point.
Design	When creating a design, it is best to begin with construction lines that can easily be changed to accommodate changes in design concept. Polylines are excellent construction lines because they are very basic, two-dimensional objects having a large amount of flexibility in their use. After the initial concept has been stored and modified, you can convert the polylines into set lines, then assign elevations to the endpoints. You then have a design with intelligence whose surface can be modeled and from which volumes can be calculated.

Report the areas of various slope ranges of a DTM.

The slope ranges for which areas are to be reported are defined in the [Slope Table] section of the TMODWIN.INI file. This table can be modified to configure the slope ranges as desired. The maximum number of slope ranges is 100. The slope range limits are expressed in terms of percent slope. All calculations are based on the actual DTM and not a secondary grid interpolation.

The [SlopeTable] section of the TMODWIN.INI file, as normally shipped with Terramodel, is set up for 16 slope ranges. To add more or reduce the number of slope ranges, edit the TableSize=# variable within the [SlopeTable] section of the *.INI file to indicate the number of slope ranges.

The lines that follow the TableSize=# entry are a zero-based list of the slope values representing the boundaries between each range. They are listed as 0 through TableSize-1. The number of such entries must match the indicated table size. The percent slope values entered within that list must be listed in order of decreasing magnitude.

Reduces the number of vertices (control points) in plines.

Terramodel aligns the filter based on orientation of the first two vertices on the pline. The length of the filter is measured in the direction of the length of the pline, while the width is measured across the pline.

After Terramodel orients the filter tube, it checks for additional vertices that are contained within the limits of the filter tube. Any vertices inside the tube are discarded. The first vertex Terramodel finds outside of the tube is kept, and the last discarded vertex inside the tube is added back to the pline. The tube is then reoriented based on the last two vertices, and the process is repeated.

Copy objects into an elevation view.

Copy selected objects from a plan view into an "Elevation" drawing in a selected view.

The position of the point along the selected baseline determines the horizontal position the view, while the Z coordinate of the point determines the vertical position in the view.

The objects maintain the layer, colour and linetype of the original points.

The name of the new object is the original name plus the baseline name and original point number, X, Y and Z.

The objects are referenced to the original object. This enables you to label a point with the original point number, elevation, etc. using EAT codes.

Apply horizontal design to a road alignment.

Select a registered HAL of IPs, check the settings and then press Enter. The result is a road fully designed in horizontal, including fitting of curves, templates, transitions, superelevation and widening. In conjunction with VAL Editor, design a long road in minutes!

Keep any of your existing curves, superelevation, widening, xlines, and existing profile, or update them.

The settings include design speed, default cross slope, pavement and shoulder width and widening ratio.

Great for forest, haul and mountain roads where the same design criteria apply for most of the length. Use WALK to get the initial alignment if based on constant grade, otherwise just pick some IPs. Use VAL Editor to design the vertical alignment. Then modify your horizontal and vertical design to accommodate variations such as intersections.

FORESTRD and a prototype file are customised according to your requirements which could match those of any road authority. The default is setup for NSW RTA.

Duplicate point removal on a layer with tolerances.

Specify tolerances in X, Y and Z. One point is retained and the others are moved to layer 0 for possible later deletion.

If "Mean Pts" is selected, the remaining point has coordinates at the mean of the other points. If not selected, the coordinates are derived from first point within tolerance.

There is also the option to generate a report.

Hints:

• DTM formation, which occurs whenever a DTM is required, automatically removes duplicate points on the layer to tolerances of approx 1 mm. The duplicate points are relayered to layer 0. This is a very quick process.
• CONVERT takes a long time to convert a lot of plines to sets, if "Dup pts ok" is OFF. It is much faster to CONVERT with this ON, then use DTM formation or GC31 to remove duplicate points afterwards.
• Similarly, Terramodel can take a long time to IMPORT a DXF or DWG file if it has to remove duplicate points as it goes. If there is a layer called DXF_NO_PT_CHK at the time of import, the duplicate points are not removed. Then use DTM formation or GC31 to remove duplicate points afterwards.
• If you use GC58 to remove duplicate sets, plines and text, use DTM formation or GC31 to remove duplicate points afterwards..

Create a two-arc set through three points.

Create sets consisting of two arcs connecting the three points in the nominated order.

This is unlike the single-arc set created with ThreePC (Cogo.. Curves.. 3 points), which uses the middle point to compute the radius and centrepoint, but the middle point is not part of the set.

The difference is most noticeable when all three points have elevations, and you are using functions that interpolate elevations along sets. For example, if the middle point is a low or high point in a kerb or channel, a correct DTM requires ARCBL to take the elevation of the middle point into account, which can only happen if the middle point is included in the set.

Create obstructions in profile view.

Where the HAL crosses selected objects, place a circle in the profile view.

A circle of specified diameter is placed at the chainage of each object. If obvert is selected, the top of the circle is placed at the elevation. If invert, the bottom of the circle. The circle will appear as an ellipse if the profile view has vertical exaggeration.

Calculate surface or horizontal areas of shapes in a roadjob.

Estimate approximate areas quickly.

This report is presented in chainage ranges. The length of shape is reported for each chainage.

Assumptions:

• Shapes are used only once in a subgrade. If a shape is used more than once, the calculated areas include the shape each time. This could overestimate the area of a shape.
• The roadway is straight. Because no curve correction is applied, this may over or underestimate the area.
• No skips. The skip manager is ignored. This may overestimate.

Compute cut volumes between surfaces within blocks.

This is ideal for computing excavation volumes in pits, mines and quarries, where there are large numbers of layers of material. Triangles are used, rather than grids, which increases accuracy.

Set up the surfaces using Surface Manager. The Finish Surface, which represents the design limit of excavation, needs to cover the extent of the other surfaces. You can also nominate multiple boundaries in plan (="blocks"), an elevation range, and a report style. If a .CSV report style is selected, the resulting comma-separated variable (.CSV) file can be imported into a spreadsheet application for further computation.

If a depth surface is nominated an elevation surface is created then deleted.

Intersection Design.

Design vertical alignments in intersections. A limit of nine alignments allows for four kerb returns, four splitter islands and a roundabout.

This simplifies a process which would otherwise require repeated use of profile editing, 3D, DTM creation, etc.

Before running this function, design the intersection in 2D and tile plan and profile views so that you can see the updated intersection contours immediately the vertical profiles are edited.

To use this function:

• Select Settings to nominate up to nine HAL/VAL pairs.
• Select Recompute to create 3D points along the alignments (on the nominated layer using the 3D.TML settings), regenerate a DTM of the intersection and show updated quick contours.
• Selecting the radio button for a pair, makes that alignment active, highlights the alignment and its direction in the plan view, and fits the profile view showing only referenced profiles.
• To edit profiles, make the desired alignment active with the radio button, exit the Settings dialog, pick the design profile then locate the point in the profile to edit.

Interpolate or extrapolate heights from two 3D sets onto points on another set.

For each point on the set to be changed, elevations are computed at the intersection of the perpendicular bisector and each selected 3D set. The new elevation of the point is on the grade between the computed intersection points.

The construction lines can be created as plines on the current layer to show which points were used to computed which elevation.

If one of the sets is a DTM edge, and the other draped onto the DTM parallel to and inside the edge, this TML can be used to extend a DTM outwards at approximately the same grade.

Create a point at a distance along a line between two points

Nominate two points, and a horizontal or slope distance along the line from the first point to the second point.

Once the first point is created, the default distance is the last distance entered, which will be measured from the point just created. The message area keeps track of the total distance entered. To restart computing the measurement from the first point, cancel and restart the function.

To extrapolate, enter a negative distance or a total distance greater than the distance between the points.

If the points have elevations, the elevation is interpolated.

Move points onto nearest Xlines.

This is useful when working with surveyed cross section point data.

For each Xline in turn, this TML finds the chainage where the xline crosses the HAL, then finds all points within both the specified "Chainage tolerance" value and the extent of the Xline, then moves each point to the chainage of the Xline while maintaining the offset from the hal.

If the Xlines are perpendicular to the hal, and the chainage offset is less than half the spacing between the Xlines, this has the same effect as moving points onto the nearest Xline.

If "Create XSects" is ticked, the points are used to create cross sections in the XSect view. The points in the section are not sorted on offset.

Add points into sets based on maximum horizontal distance.

This is especially useful where points are too far apart for DESIGN to work properly.

Change zero elevations (Z = 0) to no elevation (Z = *).

2D points are often stored in DWG and DXF files as 3D points with elevations equal to zero. Because these elevations are retained when imported into Terramodel, they interfere with DTM formation.

Be careful as there are cases where zero elevations are correct, especially near coastlines.

See also GC53 to retain elevations but exclude them from DTM and ELEVATION to change elevations.

Combine elevation of point and DTM.

Compares the elevation of each point with the elevation interpolated from the DTM layer and changes the elevation. The options are: DTM, DTM - Z, DTM + Z, Z - DTM, -Z - DTM, DTM * Z and DTM / Z.

For example, use this to convert drill hole depths to absolute elevations.

The DTM only option replaces all elevations with interpolated DTM elevations, unlike DTMPTS which only sets the elevations of 2D points.

Create solid thick lines.

One application is to show line marking.

Creates two parallel plines on either side of a pline or set, a closes the ends then hatches each closed pline. The offset is half the nominated width in plan units. The pline and hatch are created in same layer as the original line with the colour of the layer. The hatch is solid with spacing = 1.

The resultant line appears to be solid, at nominated width in ground units on the display, independent of view scale and smooth around bends.

The line will be plotted wider by the thickness of the pen assigned to its colour, so use a thin pen and solid linetype.

Compare sum of lot areas against boundary.

Report the area of each selected set, and compares the area of the largest set against the sum of all the others.

In a subdivision, the area of the boundary lot should equal the sum of the areas of all the other lots. If the difference is the size of a lot, look for omitted or duplicated lots of that size. If the difference is smaller, look for incorrectly drawn lots.

Compute DTM areas by slope ranges within boundary.

Within selected boundary polygons, compute the both the planimetric (horizontal) and surface areas of the DTM for slope ranges.

Adjust points for a non-vertical antenna.

Adjust points that have been computed at a fixed height vertically below a target or receiver on a pole, when the pole was actually perpendicular to the surface. One example is a GPS antenna mounted on a four-wheeled vehicle.

For each point, the true antenna location is determined at the antenna height above the point. By projecting the antenna length from the true antenna location in a direction normal to the average slope of triangles touching the point, a new point is created uphill from the first point, optionally on a new layer.

Draw a pline or set arc from any three parameters.

Chose one of 10 Types of arc, for example "Start, Center, End" or "3 Point".

ARC defaults to the last Type used.

Similar to ARC, except you can specify whether to create a pline or set.

The arc is drawn from the first point to the last point.

If a radius is used, a negative radius will draw the arc on the right-hand side.

Match extents of boundaries

For each of two DTM edges, copy the points from the other set which are outside the selected set on to the layer of the selected set, then create a new DTM edge.

The result is two new sets covering the same maximum horizontal extent of the two sets, but with different layers and elevations.

The areas and volumes between the new surfaces are shown in the message scroll area.

Use this to compute volumes between two surfaces where the model is assumed to batter from the extent of one DTM to the other.

Set elevations of labelled contours.

Find contours on selected layer within a specified distance from selected text, and change the elevation of the contour pline to match the value of the text.

Convert the plines to sets, and you have created an approximate DTM surface from a labelled 2D contour plan.

If the tolerance is too small, some contours will be missed. If you have only labels on index contours, and the tolerance is too large, some unlabelled contours will be asigned elevations.

By default, plines with elevations already are not changed. To force a change, tick "Do all".

Text containing non-numeric characters will be ignored.

If there are insufficient labels, the other contour elevations can be set manually using GCMULCON, GCONECON or PLTO3D. If there is a DTM, you could interpolate the contour elevations using ELVPLINE or regenerate the contours.

Import Geocomp data and survey data using the Geocomp Data Collector Interface.

Raw data from a number of different data collectors can be downloaded, converted to a Geocomp Standard Field File (.FLD) and then converted to Geocomp SDS format. (The FLD file can also be imported into RDE via a script).

Geocomp SDS format records the computed coordinates in a .PTS file and the feature code and stringing in a matching .STR file. The resulting 3D points are assigned block or symbol, layer, name and group according to the feature code. They are strung where required with sets of configurable layer, colour and linetype. Blocks representing tree canopies can be sized by the recorded radius.

Geocomp PTS/STR files, whether exported from Geocomp or the Data Collector Interface, can be imported. See also the Geocomp import-related TMLs GC09, GCHALIN, GCVERIN, GCCONIN, GCDTMIN, GCPLTIN, GCCSVIN, GCINSBLK, GCJOINMP, GCJOINPT, PTJOIN and IMPORTGC.

GCIMPORT is installed with Terramodel supplied from Geocomp Systems. GCIMPORT can be launched using a Geocomp button on the toolbar or by typing GCIMPORT.

Select "Import .Pts/.Str" button and browse to select a GEOCOMP .PTS file. The .STR, .ANT, .LTO, .DMN and .HAL and .VER files of the same version will also be imported.

This dialog also allows for selection of the ENT table. This table controls the layer names, descriptions/names, colours, linetypes and symbols according to the Geocomp entity number. If the Geocomp files have been derived from survey, the entity and stringing have been worked out from the feature coding.

The layer name can be the short description, long description or moss string code in the ENT file. The entity number may be added to the front of the layer name.

The object name (sometimes called description) is derived from the Geocomp string description, the short name (alpha-code), the long name or the moss (point or string) code in the ENT file.

The Geocomp entity is set to the Terramodel group.

If "Map Points and Circles with Blocks or Symbols" is selected, blocks or symbols are automatically placed by group. See GC09.TML and GCINSBLK.TML.

Configuring the Data Collector Interface

• The Geocomp Data Collector Interface is a DOS application called from Terramodel for Windows. Geocomp users will pick it up quickly. For everyone else, we recommend training. Carefully read the Geocomp documents referred to, in particular the Geocomp Reference Manual GC6, Chapter 10 and Appendix D, available in .pdf from Geocomp Systems.
• sufficient environment space and free conventional memory must be made available. ANSI.SYS must be loaded to download from any instrument other than a Geodimeter.
  • For Windows 95 and 98, include the line devicehigh=c:\windows\command\ansi.sys in your C:\CONFIG.SYS.
  • For Windows NT, 2000 and XPPro, include device=%SystemRoot%\system32\ansi.sys in your %SYSTEMROOT%\SYSTEM32\CONFIG.NT.
• The default location for this interface is C:\Program Files\Trimble\Terramodel\Geocomp. If the software is installed anywhere else, you will need to edit the TM.BAT and the GEOCOMP.PAR files. Contact Geocomp Systems for more information if required.
• You also need to select your data collector type, communication parameters and coding character positions. See the Geocomp manuals for an explanation of these settings.

Downloading from the Data Collector or Instrument to Terramodel

1. Open a new project
2. Run GCIMPORT
3. Select Data Collector. This will launch the Data Collector Interface.

5. Select 3, Data Collector Interface
6. Select 2, Transfer from [currently configured data collector]
7. Download the file from the data collector. This creates a data file with a six-digit number (with a file extension dependent on the data collector format) in C:\Program Files\Trimble\Terramodel\Geocomp.

   Alternatively, download the data using some other software (e.g. Terramodel Download Script, Geocomp, SokkiaComms, Leica Survey Office, Nikon TransIT or Geodimeter Software Tools) and copy the raw data into the C:\Program Files\Trimble\Terramodel\Geocomp directory with a name six-digit number format.

   If you get a black screen, you have an ANSI.SYS problem. See above.

8. Select 3, Create Standard Field File. This is a raw data file in a standard Geocomp format.

   If you need a control point file, create it in advance using GCPTSOUT.TML and a target of Geocomp CRD. The .CRD file name is in the format CONTnn.CRD where nn are digits indicating the control point file number. The character positions of the station description in the name of the point are critical.

9. Optionally, Select 8 to edit or view the .FLD file, or use any text editor.
10. Select 4, Reduce Standard Field File. This creates a pair of Geocomp .PTS and .STR files. The .PTS file contains the coordinates and the .STR file contains the stringing and coding information.

Replace circles with trees

Place a symbol or block for each selected circular set, scaled to match the diameter.

The most common use is to place large numbers of tree blocks scaled to fit canopy or trunk diameters.

Delete the original circles if you want.

For a few circles, UNITBLK or BLOCK Insert may be better.

If the circles are plines, CONVERT to a set first, then set the group with GC52 or SGRP.

The block is chosen according to the group of the set, and a mapping file. This is the same mapping file used by GCIMPORT and GC09. See Geocomp.map for an example which includes an explanation of the format.

GCIMPORT can import survey data including circles. If you elect not to "Map points and Circles with Blocks or Symbols" at the time, you can use GCINSBLK to replace the circles later.

Use GC09 to place blocks or symbols on points by group. To create points at centroids of sets or plines, use GC35.

See also LABELSETS.

Tree canopy blocks included with Terramodel include: Tree1 to Tree8, Tree coniferous type 1, Tree deciduous type 1 to 3, GCSYM423,437,438,452 and 453. Symbols 100 to 109 are provided as both symbols and blocks SYM100 to SYM109. Some of these are illustrated in the Terramodel 10.1 User Guide pages 171 and 200.
