1Introduction

This manual is the second part of the Elta soft-ware user manual. It includes the description ofthe application programs of the software pack-ages Special and Professional.

Depending on the configuration of the instrument(servo and target recognition with RMT and pas-sive prisms) some of the functions of the pro-grams Multiple Rounds and Traverse are dif-ferent in some details from each other. Thereforethe screens of the manual could be slightly differ-ent for the different instrument types.

We would like to wish you every success in yourwork with the Elta software. If you need anyhelp, we will be glad to be of assistance.

Yours

The programs Traverse, Intersections of Lines andArcs, Transformation and Roadline Lite are im-plemented in the Elta software packages Spe-cial and Professional. These programs are usefultools for the daily surveyors practical work in thefield.

Traverse

It is possible to measure from a start point S, upto a maximum of 20 Traverse Points P and closeon an end point E. The Stationing at S or E canincorporate up to 20 backsight points BP.

New Traverse

After program start, the computer searches for acurrent Traverse. If no traverse is found then anew traverse is initialised and the first step is toinput the actual instrument height and the firstbacksight target height (other parameters canalso be controlled at this point):

to confirm and record the parameter input

Measurement of a Traversethrough back and fore-sights, and computationwith a choice of adjust-ments. During the Traversemeasurement it is possibleto measure detail points(side shots) which can alsobe corrected at the adjust-ment stage.

After a set of observationsmeasured in one telescopeposition only the traversepoints measured withTrimble 5600 and Elta S areselected and aimed auto-matically with Elta S.

The methods for Stationing on a known pointand Free Stationing are described in the Station-ing chapter.

If there is no Height Stationing then the traversewill be computed without heights and the heightsoftkey will show Zoff .

After Stationing, the traverse will begin with themeasurement of the foresight to the first TraversePoint TP1.

Continue Traverse

If after the program start an unfinished Traverse isfound, then the program will ask if you wish tocontinue the existing traverse:

At the End Point E of the traverse it is possible tomake further backsight measurement (no fore-sight measurements are possible).

It is possible to finish the traverse without closingon a point of known coordinates and directions.

In order to correctly control and adjust the trav-erse, it is necessary to close on a known coordi-nate and direction either by stationing on aknown point or by free stationing. You need toconfirm the continuation of the end point by:

Transformation with neighbourhoodadjustment

Doing a weighted distances computation ofneighbourhood points the residuals of the identi-cal points will be reduced to Zero. The trans-formed non identical points will be re-adjusted bynew residuals depending on their position to theidentical points.

The transformed points will be stored with thepoint identification PI and their new coordinatesin the project file.

The following theoretic recording example of averification point 777888 gives more informationhow the points will be stored:

The 1st measure of point 777888 is registratedon address 3 (Y=1100.000m). A 2nd measure-ment with Y=1100.200m leads to an averagevalue of Y=1100.100m. This average is stored ataddress 7 and gets the signature A (Average) incolumn 119 in the project file. The 2nd pointmeasured is registrated at address 9. All Meas-urement points will be signed with a M incolumn 119.

The 3rd measurement of point 777888(Y=1100.400m) leads to an average value ofY=1100.200m (together with the 1st and 2ndmeasurement), recorded at address 14, signed aswell with an A. The measurement value is regis-trated at address 16.

The program goes automatically into the Editor tocall up the start point P1 from project file.

to measureThe program stays on in the measurement menufor further measurements.

to measureUse Edit to switch back to the Editor for callingup points from project file. The program remainsthen on in the Editor. Press for going backto the measurement menu.

The operation and softkey handling is similar tothe Connecting Distances measurement in LocalSystem.

The Connecting Distancewill be calculated by call uppoints from project file orby measurement. A combi-nation is possible.

If Verification Point is switched off you notwill be asked for it.

If the point verification is not needed, itsbetter to turn it off. For large project files itcould be a time consuming search function.
