Introduction
Enwinding surveys establish points by travers bassline or other methods to obtained information required for engineering designs and to set out construction from design drawing by used of these control points.The nature of the data required to be collected , the techniques, instrumentation to be used and the use allocated to the data collected all have a role they play in determining the nature and type of surveying to be carried out.With the new age of computer, there have been drastic and yet amazing changes in profession as pertaining instrumentation and computation and data processing .Total station have replaced plan tables and software has replaced the unwieldy mathematical computations that were previously done through analogue methods.In fact the practice of surveying and mapping has changed very greatly with the automation nowadays and this has given an all new view to surveying as a discipline.Investments in the surveying filed by major commercial interests such as big companies (e.g.LICECA,TOPCON,TRIMBLE and SOKIA) seek to improve their knowledge in these fields such as Global Navigation Satellite Systems (GNSS),Geographic Information System (GIS).The total station is one such advancement in instrumentation that is currently top notch because it contains software components coupled with both an electronic theodolite and distomat, the instrument is very handy in surveys today and is preferred by many surveyors .A difference among all popular survey software on market today like Civil Design Software (CDS), surveying and engineering LISCAD software, Pythagoras, Microsurvey, are: the vary cost to graphic capability function and user friendliness as well as their respective ability to handle large data and heavy projects.Carlson survey 2009 software is one of the newly developed software made by Carlson Software Inc from united states.This software consists of program integrated with AutoCAD into one package .The capacity of the software has been improved to meet the requirements of a task and fulfill the satisfaction of the user.The software was designed in a complete package that an output needs not to export to another application to produced final results.
A complete survey automation system is basically a combination between the total station and survey software in order to process survey data up to the production of final results in form of maps graph in their softcopy and or hardcopy .wherethere are many applications software's on the market today that help in engineering survey works it's important to implementation and assess each software carefully to fully understand its operations, advantages and disadvantages .This paper aims to carry out the implementation of Carlson survey software for engineering survey works and compare it to CDS software.
In this research covers a case study in which the sample data by total station from a special selected site in the vicinity of University Technology Malaysia using Carlson surveying 2009 software for processing and manipulation of data.For this study comparison between CDS software and Carlson survey software and demonstrate how suitable each is when used complementarity to total station equipment .alsothis software is a pivot of further assessment into the approaches of adopting and implementation of Carlson survey software in Libya based engineering survey work with hope of improving the survey methodology in Libya from basic to more advanced automation methods.

Data Acquisition:
Data be used for the research project was acquired using a LICA TPS307 series instrument with control being obtained from GPS observation.This instrument is a high quality electronic total station designed for the engineering and construction site surveying.The GPS observation were carried out prior to the topographic survey using a Trimble 4800 receiver for a very short baseline of two point UTM01 and station 2 STN2 which were to be used as control and orientation later in the process of traversing and detailing .The data from the GPS observation was downloaded and processed in Trimble total control software.the GPS benchmark (UTM 01) that was using to establish coordinates of another point for orientation .An area of the whole place was to be about 800m 2 having a total perimeter of about 400m.For data collection it would be necessary for at least one total station (LICA TPS307, the trigger button functionality and endless motion screws as well as many tripods to enable us to set up many simultaneous targets, as well as 3 or 4 reflector prism ranging .For determination the coordinate of point we use from GPS needed 3 station , first the total station was put on known position point (UTM01) then entered the coordinate of UTM01 as the station point in total station.second was interring the coordinate of second point as back sight point.Then set the horizontal angle zero in the back-sight direction.For gathering coordinate of required points commence to producing detailed plan should gather the coordinate of every detail in this site.Although gathering the detail depended on the scale of the plan.The sit contained building, tree, float way, street, tower and gathered the coordinate of all of them.Also for creating the counter coordinate gathered of topographies.After that because the other required points were at the back of the building there was need to change the position of the total station on the second station and continued the observation from there.In this station was got other corner of the building float way and terrain.The last station was station three in whish gathered the coordinate of one big tree, tower and terrain.

Results and Analysis
The results are presented in two forms; those obtained from CDS data processing and those obtained using Carlson survey 2009 software.The detailed plans are DTM in both cases are drawn based on the same study area but processed separately in the two different software.The results as obtained from the methodology followed in this research include detailed plans, DTMs in the form of contours, TIN and GRID.The detailed plan as showed in the Figure 1 represent the area of study (observatory area -University Technology Malaysia).The initial CDS results, after being exported to AutoCAD for editing and improvement to be carried out on the detailed plan is presented as in Figure 2. The 3D presentation of TIN models in CDS software is also represented in Figure 3, which attempts to create a better height and visual interpretation of the topography for users of CDS software.As shown in the Figure 6 the TN results show a network of triangles connected by vertices of elevation points as surveyed from the field work and effectively depicting the terrain and topology of the study area.Figure 7 shows the three dimensional model of the TIN version of results as depicted by Fgure 6. 3D GRID representation Figure 9 tend to give a broader perspective of the topological qualities of the area surveyed while 2D GRID representation Figure 8 may sometimes have limited visual capabilities and may be hard to interpret or even un-interpretable to the untrained eye and no technical or experienced personnel.It is for this reason that the 3d representations are normally preferred despite their demand for more storage space.Carlson software is capable in downloading raw data from various types of total station and external data recorder module.This software support 100 percent raw data download from total station brand Leica, Geodimeter, Topcon, Nikon sokkia, Zeiss and Laser.It also supports other external recorder format such as SurCE, SurvStar, G2, Dozer2000, TDS, SDR, Surveyors Assistant and Geodat.
Raw data that had been downloaded to this software be processes stored as raw data format file .It has been discovered that Carlson 2009 Software is easier to understand the raw data format.Rows and lines from detail survey will be arranged and marked clearly as shown in Figure 10.Every detail point's information will be displayed completely as any point oriented, where it is faced, back station information, instrument and prism height, bearing, slope distance, vertical angle and detail code.The format is different with CDS software, where information on all detail is showed as basic in the stadia window like Figure 11.It showed all information needed in the survey data processing but needs great understanding to know the information array displayed.
Carlson Survey 2009 Software is not only capable of generating contour lines, but also capable of generating 3D dynamic view and from which height analysis can be carried out easily.Contour lines at field work can be generated without the user being prompted to manually generate the triangulation initially as required in the CDS software.This specification can fasten the generation of detail survey plan.Contour lines that have been generated can be fully manipulated like line smoothing, labeling, color changing, line width and type.All functions are in contour menu on DTM-contour module without worrying if contour lines damaged and there is no need to reprocess the contour.
Three dimensional DTM views can be generated via Carlson Survey 2009 Software.Accuracy on DTM generated is high and the users are able to have the option to choose the model method such as triangulation, kriging, polynomial, and least root mean square (can be viewed on Figure 6 and 8) However, CDS software can only use triangulation method to generate DTM.Dynamic three dimensional can be viewed on 3D viewer window and users can rotate X, Y and Z axes to view 3D clearer.
3D view generated by Carlson Survey 2009 Software (Figure .7)can be shown by color representations foe every elevation.With different colors, users can make height analysis much easier only by using bare eye inspection, while CDS software is only capable of generating 3D view in one color (Figure 3) which is a major difference especially for data representation to non-skilled or nontechnical personnel.
The usage of AutoCAD platform in this software makes graphical editing works much easier and faster.Users who have been familiar with AutoCAD environment will discover that Carlson software can help then in editing the plan two time faster.This because of the AutoCAD handicap such as LISP routine and editing toolbars plus new specifications on Carlson survey 2009 software, i.e.Annotate menu which helps completing detailed plan faster.Carlson Survey 2009 Software has the features that can help to draw legend, north direction, map frame, and grid boxes automatically.These features are not available in CDS software.
In the research, Carlson Survey 2009 Software is capable to plot any plan with any scales.This software uses interface plotter from AutoCAD software.In order to do checking, user can view the plans contain before it is actually platted using Full Preview button for whole checking and Partial Preview foe partial checking.Table 1 shows a summary of the comparison between six aspects that are needed in any survey software to generate detail plan survey.

Conclusions and recommendations
Time foe processing: whereas both software are capable of producing nearly identical results, the time for processing required for both greatly difference, In CDS the processing is done automatically in the CDS software suite but later needs to be exported to a CAD software such as AutoCAD for further and more refined editing this makes the process longer the Carlson Survey Software where the software is CAD based and tools for editing and processing are combined in the some suite.The recommendations list drawn in this study as: 1. Carlson survey 2009 software to be applied and adopted as the overall engineering survey software by surveyors in Libya due to the numerous advantages and functionalities it presents to surveyors and engineers.2. GIS module and menu in Carlson survey 2009 software can be used to establish the database for the engineering surveys on numerous project in Libya from road design to construction and can manage all contour plans, documents, coordinates and heights information, traverse and tachometry data and also boundaries marks location status.DTM can be used as the 3D base map for managing the information .3. survNet menu for network least squares calculation which is essential for raw survey notes reduction.SuevNet handles any combination of total station , GPS and level loop measurement.4. Carlson survey 2009 software combined the surveyors preferred language of point based coordinate geometry (COGO) commands within the AutoCAD drawing environment better than any other survey software in AutoCAD. 5. Hydrology module can be used in hydrographic survey to determine the thalweg for boundaries located along a river.6.More research and studies be carried out in the engineering survey automation filed especially in other undeveloped in countries like Libya .7. Used Carlson survey 2009 software in implementation and building of survey and information database from acquired and information processed which would in turn be used as a GIS or land information system for surveyors .
