3.2.4. Standard Model Naming Conventions

The following is a list of common Data Groups (MODELS) and associated features that shall be used. The Roads and Traffic Authority (RTA) requests you begin your data group name with that highlighted, to assist with the data transfer.

For example, a Ground features Data Group model name should begin with SURV.

3.2.4.1. Survey Model Naming Conventions

Group Feature

Ground (surv) Existing features that the Constructor will find on the ground, above the ground as well as below the ground. These are to be clearly labelled (Note:- utility details may be individually grouped)

Boundaries (surv) Current cadastre Surfground (cont) Ground contour features Triground (tri) Ground triangulation features Utilities (Util) 3D details of each utility service, including utility type

3.2.4.2. Design Model Naming Conventions

Group Feature

Design (des) All proposed geometry and features of design (except drainage and cross-section)

Longsection (lsec) Existing longitudinal section features Section (xsec) Cross section features - existing and designed surface Drainage (drain) Drainage features Surfdesign (cont) Design contour features Tridesign (tri) Design triangulation features Merge (merge) The merging of design and ground data groups Concrete Jointing (conc) Concrete jointing design features Boundaries (surv) Current cadastre


3.2.5. Situational Examples

3.2.5.1. Field Practices

In an effort to minimise confusion over pickup practices for the new codes, the following section addresses some possible areas where confusion may occur. Some existing codes have also been included. The term Excluded from triangulation can be interpreted as either using IGL in the pickup, or to use a 019 mask in the triangulation process.

3.2.5.1.1. Stairs - Outside

The Macro symbol will be drawn between the 2 pickup points in a repeat pattern. If there is data picked up underneath the stairs, then they should be excluded from the triangulation.

3.2.5.1.2. Heritage Items

These codes are designed to be used as part of the office procedures. Insert a single point in the centre of the area for each of the relevant codes, & the appropriate macro symbol will be drawn centred around the point. These items would generally be excluded from the triangulation calculations.



3.2.5.1.3. Pavement Arrows

The points should be picked up at either end of the through arrow, in the direction the arrow is pointing.

The points should be picked up at either end of the through arrow, in the direction the arrow is pointing.

The first point should be the centre of the base of the arrow & the 2nd point should be adjacent to the tip of the arrow, directly in line with the centre of the base of the arrow.

The first point should be the centre of the base of the arrow & the 2nd point should be adjacent to the tip of the arrow, directly in line with the centre of the base of the arrow.

These features can be either included or excluded from the triangulation, but it should be noted that they are linked string features, not point features.

3.2.5.1.4. Pedestrian Crossing Approach

Pick up either end of the zig-zag line, and the macroline will be stretched between the 2 points. These strings should be excluded from the triangulation, particularly if it is located on a vertical curve.

3.2.5.1.5. Chevron Marking Left & Right

Pick up points along the chevron line, ensuring that you use the correct label. CV (Chevron Left) will put the chevron lines on the left as you are picking up the points, whilst CY (Chevron Right) will put the markings on the right. These strings should be included in the triangulation.



3.2.5.1.6. Pedestrian Crossing - Zebra

This feature has been designed to be picked up with 2 shots 1 on each lip or edge of pavement, at the centre of the crossing. The macro line will be draw to scale in a repeat pattern. These strings should not be included in the triangulation.

3.2.5.1.7. Speed Zones All Speeds

All speed zone markings should be picked up in the same manner as illustrated for the 60km/hr marking. The pickup points are 1 point at the base of the text, on either side of it. The strings could be either included or excluded from the triangulation.

3.2.5.1.8. Traffic Light with Outreach, Sign with Outreach and Light with Outreach

All 3 feature types should be picked up in the same manner. Pick up the centre of the post, and then a point directly underneath the furthest point of the outreach. The macro line will be stretch between the 2 points. All these features should be excluded from the triangulation.

3.2.5.1.9. Tree Foliage Single Point Pickup

These features can now be picked up with a single shot, at the same time as picking up the tree trunk. The diameter of the foliage is determined, and the appropriate code given to the foliage shot. The points can either be included or excluded from the triangulation.

It should be noted that the traditional style of foliage pickup (the TR strings) is still available where this method is not suitable or practical.



3.2.5.1.10. Hotspot

This feature can be coded either in the field or in the office. The first point is where the photo was taken from, and the 2nd point is the centre of the photo target. The string should not be included in the triangulation.

3.2.5.1.11. Culvert

The culverts should be picked up with 2 strings for each box culvert section, as shown in the diagram above. The intention is to pick up the invert of each side of the culvert, with a point either side of the road. The code of each string relates to the height of the culvert.

In the example given, the strings B600 & B601 represent the invert of each side of a 600mm high box culvert cell. The cell could be any given width. It should be noted that only standard height box culverts are represented, but this should cater for most instances.

All culvert strings should have valid levels. They would generally be excluded from the triangulation via a 019 mask.




3.2.6. MX String Modelling Concepts

3.2.6.1. Basic Concepts

The basic concepts of data storage in MX comprise models, strings and string elements. The facilities which enable access to the data and computational functions of the system consists of two level command language.

3.2.6.2. Models

Models are sets of data representing either a physical entity such as the surface of an area of land or an abstract entity such as a model of traffic noise. Models can be used to define any surface, network or set of features. Examples of models include:

3.2.6.2.1. Surface Models Existing Ground Surface

Substrata or Geological Models

Proposed engineering works, roads, railways, dams, runways etc.

3.2.6.2.2. Feature Models

Ground detail such as hedges, fences, power lines etc.

3.2.6.2.3. Network Models

Gas, Water, Electricity, Telephone, Drainage etc.

3.2.6.2.4. Abstract Models

Noise and visual intrusion, Cost models etc.

3.2.6.3. Strings

A model consists of any number of strings of data. A string can be thought of as a line on a plan with reduced levels and other information held as attributes. A string can be of any length and is identified by a unique four-character label. A string is composed of any number of points.

3.2.6.4. String Points

A string point can consist of any number of items of data describing entities such as easting or X co-ordinate, northing or Y co-ordinate, reduced level or Z co-ordinate, chainage etc. If spatial co-ordinates form part of the point they must occupy the three dimensions. Each point is assumed to be joined to the preceding and succeeding point by an imaginary straight fine.



3.2.6.5. Types Of Strings

The most commonly used types of strings for survey are:

3.2.6.5.1. Contour Strings

A two dimensional string with each point comprising co-ordinates stoned in the order X, Y and with the reduced level (Z dimension) stored in the string header information. Such strings can also be obtained from digitised information or can be generated by MX major option SURFACE.

3.2.6.5.2. Feature Strings

A three dimensional string with each point comprising co-ordinates stoned in the order X, Y, Z. Feature strings are used to define feature lines such as edges of pavement but may also be used for the general definition of a surface.

3.2.6.5.3. Point Strings

In general, successive points on a string are assumed to be joined by straight lines. However, certain types of strings represent a set of like items where a line joining successive points has no significance. Such strings are referred to as point strings, they are interpreted as a series of random (unconnected) points when defining surface curvature, e.g. electricity pits or trees.

3.2.6.6. The Mx Command. Language

Access to the store data and the computational functions of the MX system is provided through a two level command language.

3.2.6.6.1. Major Options

The top level of the MX commands are known as major options. As well as defining the model to be actioned these also define major functions of the system which operate on a model such as model. generation and editing, model updating, determination of areas and volumes; road design and general graphical functions.

3.2.6.6.2. Minor Options

The lower level of the MX commands are known as minor options. Within most major options are a series of minor options which generally perform operations on one or more strings within the model specified by the current major option. For example within the major option EDIT are minor options for adding and deleting points, for copying strings (in part or whole), for rye-naming strings, etc.



3.2.7. String Labelling and Feature Definition Conventions

3.2.7.1. General

This section refers mainly to field surveys, however, the same principles apply when recording data by digitising from existing digital and/or on paper surreys.

In general the successive points on a string are assumed to be joined by straight lines, referred to as feature strings. However, certain types of strings represent a set of like items e.g. power poles, where a line.joining the successive points has no significance, such random strings are. referred to a Point Strings and have labels beginning with the character "P".

MX is flexible In the matter of string identifiers. Four characters (either letters or numbers) can be used. The Principal has adopted the RTA's string labelling conventions. Tables of these standard Feat" String and Point String labels arse Included In a drawing specified in Appendix 1 to .the Brief and these should -be used wherever possible. Any deviation from the RTA's string labelling conventions needs to be documented and supplied to the Principal with the survey data.

For input of data. using the MX option GENIO format (see section on data transfer) generally only the left-most characters of a string label are required, however experience has shown that this practice can lead to time loss when a designer tries to match strings in a model to string data as supplied by the Consultant.

To overcome this problem a counter for each member of a particular string label group MUST be . added to a string header record.

Field 3 (columns 8 through to 11) will accept character data and shall contain a simple numeric counter flagged, with .an asterisk (') in column 8 e.g.

080C . . . *001 O.OO.O 3 -1.000 -1.000

This counter will be stored by MX and remain with the string until it is deleted.

3.2.7.2. Feature Strings

3.2.7.2.1. Order of Points

The points .along each string must be in sequential order from start to finish. ft is not permissible to itemise portions of a string In a counter direction to the remainder since MX stones the infonnation in strictly sequential order and joins each point on a string to Its numerically adjacent neighbour. If this numerically adjacent neighbour is not also its physical neighbour, invalid strings are created.

If, after changing station, it is not possible to continue particular string In the original direction, new points can be picked up in reverse order, so long as the remainder of the string is given another identifier. MX will join these two strings as one if the common joining point is shown on each string.


3.2.7.2.2. Null Levels (Non-Contourable)

As a general rule, all feature strings form part of the 3D working model and as a consequence, each change of grade along each string must be located. If, in the opinion of the Consultant, the string would have no value in this regard (e.g., a fence crossing the band of interest which is only required for plotting purposes) and consequently level data is not required a level of -999.0 should entered in the GENIO data file. This is interpreted by MX as a NULL LEVEL. Alternatively the string can be collected as a point string with reduced levels if required.



3.2.7.2.3. Selection of Points

When collecting feature strings, the selection of points is a critical operation. A -true representation in plan view of string must be obtained. If it is a string for the Survey Level Model, a true representation in elevation is equally important. This means that a reading must be taken at each change of grade as well as at each change in direction of the string.

Except in the case of strings for which level data is not required, each point in a string MUST have a level recorded as well as plan co-ordinates, even if the point is included only to represent a change in direction. If levels are not included at each point discontinuities are introduced into the string in the vertical plane and the resulting model may not be truly representative of the surface.

3.2.7.2.4. Closed Strings

When a string closes upon itself e.g. a string describing the outline of a house floor slab, the observation to the initial point must also be booked (i.e. duplicated NOT re-observed) as the last point. This enables MX to model/plot the string as a closed feature.)



3.2.7.2.5. String Junctions

Where two or more strings join or cross, the joining points must be separately booked on each string; for example two fences joining, or a gate within a fence.

3.2.7.2.6. Existing Surface Strings

Existing surface strings are extremely important. From these, cross sections and profiles are extracted and earthwork quantifies computed.

Generally, these strings are surveyed roughly parallel to the general line of the band of interest, as this means that cross sections will cut as many strings as possible. It is essential that all grade changes along feature strings are collected.

These strings can be separate, or can be a continuous fine that zigzags back and forth roughly parallel to itself. It is desirable where this type of string Is used that no gaps are left between runs as such gaps produce voids in the model in so far as cross sections are concerned.



3.2.7.2.7. Existing Concrete Pavements

3.2.7.2.7.1. General

These strings should be parallel to the pavement centerline and usually along lane lines. Points on the strings should be coincident with slab corners and changes in direction of edge of slabs and at least every 1 0m along the pavement and at intermediate points if necessitated by loss of shape in the pavement. The resultant grid of level points should be marked out and recorded in such a way as to be easily re-established.

3.2.7.2.7.2. Strings Describing Isolated High/Low Points

Any high or low sections of pavement between the nominal lanes shall be collected as separate pavement strings.

3.2.7.2.7.3. Strings at Pavement Intersections

The collection of strings describing existing features at intersections should be kept to a minimum, but MUST be detailed enough to accurately describe the existing conditions. Some duplication of booking may be required.

3.2.7.2.8. Sequential Output

In the same manner that input to MX must to be in sequential order, sections generated by MX are also sequential. Thus It Is essential that for a correct section to be extracted, the-input must be sequentially correct.

An example of this occurs where incorrect readings are taken to top of kerb and invert of gutter. It may eventuate that the top of kerb and not the invert of gutter plots nearer to the centreline of the road.

To eliminate the likelihood of a false cross section through incorrect location of top of kerbs and gutters inverts, some small adjustment should be made to the measurement to the top of kerb to ensure that it plots nearer to the fence line than the gutter invert does.

Similarly an overhanging bank, although correctly positioned, can give a false cross secction.



3.2.7.2.9. Collection of Curved Features

3.2.7.2.9.1. General

Care must be exercised when surveying curved features such as kerb returns that the feature is adequately defined (refer to Section 6 on Model Accuracy and Feature Definition for requirements). MX does not fit a curve between these points, so a curve is plotted as a series of chords. It is essential, therefore, to locate points on curved features at sufficiently dose intervals to allow a true representation to be plotted. At each point a level as well as spatial co-ordinates must be recorded otherwise discontinuities will be Introduced into the string.

3.2.7.2.9.2. Parallel Curved Features

Care must be exercised to ensure that features of this type e.g. curved kerb and gutter do not cross through poor point selection. To ensure that these strings do not cross collect points that are roughly radial from points on adjacent strings. If a parallel feature (curved or not) has a regular template it may be possible to collect only a single string (refer to the section below on kerbs and gutters for details).

3.2.7.2.10. Kerbs and Gutters

Strings describing the top of kerb, gutter invert and lip of gutter shall be collected so that a true cross sectional representation may be obtained. If the kerb template is constant and regular the Consultant will only be required to collect a single string. It is recommended that the Consultant collect a string describing the lip of gutter or if there is no gutter a string describing the base of the kerb where it joins the road pavement. The Consultant MUST indicate the following details on a plan supplied:

the limits of the regular kerb.

dimensioned sketch of the kerb template with the location of the surveyed string indicated.

indication as to which side of the surveyed string the remainder of the kerb lies.

The designer can then DESIGN IN the remainder of the kerb using MX design options. The gutter lip and gutter invert string wilt be located as a continuous line from side street to side street.



3.2.7.2.11. Footpaths

Both edges of paved footpaths shall be collected as separate strings.

3.2.7.2.12. Driveway Cross-Overs

These shall be collected and labelled to Indicate the limits and type of material used (e.g. DWnn for a concrete driveway).

3.2.7.2.13. String Link Conflict

When colleccting feature strings care must be taken to ensure that other feature strings NO NOT CROSS e.g. that a general existing/natural surface string ("NSO1 ") does not cross a series of strings describing an open unlined drain ("DR01 ", "DT03" and "DT02"), (see sketch below).

If these crossing strings do not have matching points at their intersection or if there are no points in one or both of the crossing strings a conflict arises about the levels in that area.

To resolve such a conflict MX may have to Ignore one of the links between adjacent string points. There is no guarantee that MX will ignore the invalid string link.



To remove the possibility of such conflict the Consultant has two options:

If one of the strings need not be continuous (as is the case of "NS01" above) it may be broken into .two separate stings ("NS01" and "NS02") that do not cross the other feature.

If all the feature strings need to be continuous e.g. a string along the proposed centre line ("NS03") of a new road the Consultant must double book string elements in each string at the intersection points.

3.2.7.2.14. Grade Separated Features

When surveying grade separated features such as bridges both the underpassing and the overpasslng surfaces MUST be surveyed.

To assist in the resolution of string link conflict when describing features of this type use separate shorter strings to describe the under/overpassing section. This will allow designers to exclude one or both surfaces as required when generating surface contours, cross sections and the like.




3.2.7.3. Point Strings

These are strings of related but physically unconnected features such as trees, manholes, inspection points, etc. MX does not consider the points on these strings to be joined. These points will often be allocated a null level (i.e. R.L. -999.0) and hence will not be included in the definition of the model surface. If the points In a point string do have valid levels the points will be used by MX to define the model surface.

(Point Strings MUST have labels beginning with the character "P").

3.2.7.4. Strings With Standard Labels

See Appendix 1 of the Brief for list of Standard String labels.



3.2.8. Restrictions and Limitations Imposed by MX

3.2.8.1. Restrictions

The following restrictions must be complied with:

Ground co-ordinates must lie in the range 500.00 to 9999999.999. When this restriction is applied the Principal's Representative attention shall be drawn to the variation between the true origin of co-ordinates and the local origin of co-ordinates.

Levels lower than minus 998.9 cannot be recorded. (A level of minus 999.0 is assumed to be a null level).

Feature string labels must not start with the character "P".

String labels must not start with the character "M".

3.2.8.2. Limitations

In the Interest of efficiency of processing information the content and length of strings should be limited.

General limit:

the number of points within a string to about 100

the length of a string to about one kilometre.

These arse not strict limitations, but merely guides as to what will assist processing efficiency.

In some cases it will be desirable for other reasons, to have large or long strings e.g., on highway surveys, strings the full length of the highway are desirable. These strings will generally be longer than the above guides.


3.2.9. Model Accuracy and Feature Definition

3.2.9.1. General

The accuracy of the MX ground model created from the survey data will depend upon both the accuracy of the individual spot levels and the density of coverage.

3.2.9.2. Tolerances

The levels and co-ordinates of recorded points shall be correct to within the following tolerances:

3.2.9.3. Feature Definition

The spacing of points along 3D strings shall be such that the maximum vertical and horizontal distances between the straight line adjoining adjacent points on the string and the actual ground feature shall not exceed the following tolerances:

3.2.13.2. Model Validation (Clause 2.4)

Reference: MOSS Users Manual, Published by MOSS Systems Limited, MOSS House, North Heath Lane, Horsham, West Sussex, RH12 5QE, England. ISBN 0 86260 009 X

The final Digital Terrain Models (DTM) must conform to the following limits when analysed by the standard Moss Validation procedure (Ref: - Moss Manual Chapter 5, Survey Accuracy Validation). The validation strings are called QQ strings and are observed independently of the detail survey observations.

The approximate position of the QQ strings shall be:

Generally, point spacing along QQ strings is to be less than 10 metres and at all changes of grade. Minimum length of QQ strings will be 100 metres.

The validation criteria are as shown in the Table G73?A.2, with the limit being the mean vertical and lateral difference between the QQ string points and the section string derived from the model. The confidence interval for the means is to be 80% in accordance with the Moss Manual. The validation criteria apply for each Zone of Table G73/A.2. Only points on QQ strings within each Zone shall determine the mean vertical and lateral differences for validation purposes of that Zone.

Table G73/A.2 - 80% Confidence Interval for Vertical and Lateral Means for Points Compared with QQ String

Zone Zone Limits

Number Features Horizontal (m) Vertical (m)

1 Road, bridge & drainage when located as natural feature Mean 0.03 Mean 0.015

2 Other detail Mean 0.15 Mean 0.15

3 Road side Mean 0.06 Mean 0.03

4 Nominated Special Features Mean 0.01 Mean 0.005

Refer to Annexure G73/J for typical cross section showing zones and features contained within each zone.

The horizontal limits are used only when the QQ string is checking an identified 3D feature string.
