Transfer vertical datum with GNSS system

Temporary Bench Mark or TBM setup is compulsary for all the enginering survey. The conventional method is by auto level to transfer vertical datum from known bench mark. However, no all the places have established JUPEM bench mark especially undeveloped area. According to the survey fees 2001, we need to charge one day working survey fees for 1.6km to transfer reduce level (2nd class acccuracy). For example, the site is 16km apart from the known bench mark and the fees will be 10 days working fees. Land surveyor will happy to have this fees but customer will claim the cost is on "expensive" side. It is normal scenario in cost dealing with client either government or private. 

One of the govenment officers had suggested to me that transfer TBM by total station which is much cheaper than auto level and subsequently can reduce the cost. Conceptually total station able to transfer height and accuracy wise is an issue. I did try for this method for around 5km (BM to BM) and I had bad result when closed to another BM. There are many factors such as tape measuring, weather, the stability of instrument and etc.

Cost bidding is important to get a project but in win/win situation. Land surveyor also do not want to get a project if no profit margin just to earn a project. It is a good practise that we need to prove the bench mark in position before establish the TBM. Distance between bench mark to bench mark is around 1km but it is hardly found in city or town. This is an additional cost to land surveyor and are the surveyor charge to client? The smart client will deny to absort the cost because he can claim that he do not need to 2 bench marks value to get a reduce level at TBM.

The technology of GNSS system is best solution which I have tested and it can be done in less than 1 day job. Observation from bench mark to TBM and subsequently to another known bench mark for 1 pair of GNSS units system. If there are 3 units and the task can be easily done in 3-4 hours and no surveyor requested on the spot. A well-trained labor or assistant surveyor is good enough in setup the TBM. In cost wise, we able to reduce to a reasonable rate because need to iccur the cost of technology. It is win/win situation that land surveyor get the project and the client happy the cost charge to him and finally both parties contribute service/product to community and country.

The accuracy of the technology is nearly perfect which I can say above 2nd class accuracy but please do not forget apply the national Geoid correction height from JUPEM. I did one TBM from 2 bench marks recently for around 5km and the result nearly prefect.

MyCad - E Cadastral System Software

Presently, I understand there are a few companies created e-cadastral software in the market such as Mapinfo, Landsoft, Mr. T and today I want to introduce Mr. Ben with his MyCad software. According to him, he is a software programmer which happened to work with F2F system before, currently developed a program for e-Cadastral to digitizing/key in field data into 16 ascii file for submission. His program is much cheaper than other companies currently.

Below are some of the program's functionality and description. 

  • Solar and Base line computation
    • Solar computation which up to date with almanac 2012 and also Baseline computation which required by Jupem
  • Survey Observation includes DFT, Datum, Traverse, Brg Close, Close Statement, Online, Offset, TT Mark, Check Angle, Check Dist and Check Ang/Dist.All survey observation types are available to user to create the required survey data for submission.
  • Closure and Meridian correction (C/M Correction).Apply Closure and Meridian correction by clicking on the mouse. Correction will be applied automatically according to standard practice in field survey.
  • Computation engine
    • Computation formulas are include to compute Traverse Misclosure, Direct Line, Connection Line, Lot Area, Coordinate, Area Comparison
  • Date/Time editing module to help user change observation Date/Time
    • User is allowed to re-sequence the observation sequence and also edit the survey Date/Time. Date/Time is a requirement by Jupem to detect either the data is create without doing field or not. So program will automatically adjust the Date/Time for each observation as if the data is really done on the ground.
  • Compliance with Jupem eCadastral requirement
    • Data will be exported to 16 Jupem ASCII following the format of eCadastral.
  • Import/Export Jupem 16 ASCII data
    • Function to export ASCII for submission and also allow importing 16 ASCII data created from other program so that data will be automatically fill in.
  • Import DXF Pre-comp plan to help user on data computation and data entry
    • Import DXF Pre-comp plan so that user could just select/compute data during fill in observation data. In other words, user just selects the line/point to fill in data without any key in using keyboard.
  • Supportive functions to help user on computation and data entry
    • Functions that will ease user during data entry and also user friendly
  • Export printable reports
    • User could export reports such as field book, solar computation, traverse misclosure or etc in 3 types of formats, which are Microsoft words, html and text file.
  • Jupem 16 ASCII data checker to validate and highlight error in ASCII
    • After data entry at finished, there is a module to check the data exported before doing submission. If data contains error, it will be highlighted with error description so that user could rectify and make adjustment on data.
  • Include free 1 day training on how to use the program (fees will be charge for transportation outside Klang Valley/KL)
  • Support will be provided free for 1 year
    • Updates will be emailed to user for free and phone/email support in case user face problems during using the program
Please contact the below phone no. for program demo or enquiry

BM M0032 at my primary school

This is my primary school but there are many changes especially this 3 storey buildings. In those day, 80-an. There were 2 row of buildings. One was wooden class rooms for standard 1 to 3 which have been replaced by the above buildings. The opposite site of this wooden class room was concrete 2 storey classroom for standard 4 to 6. I did not realise that there is a bench mark inside my school (because I was not land surveyor during there period) until last 3 years I found it inside the school compound. The bench mark is M0032 and reduce level is 3.366m.

Clarification of GNSS test

According to JUPEM circular 1/2008-Appendix A1, there are two methods to carry out GNSS calibration. We can either use tribrach or mount the GNSS gadget onto the pillar screw. I did discuss with District Surveyor on this issue because initially we understand that the antenna height should measure from the GNSS gadget’s marker to the survey station. Thus, we also applied the same concept measured the antenna height from the marker to the pillar and subsequently to the top of the screw. However, we still unable to get the acceptable result when compare with JUPEM reference.  

The kindness of the District Surveyor has explained to me the content of this circular. The antenna height should measure according the below diagram. 
 Please take note that antenna height will be negative which equal to the height of the screw.

The second clarification is regarding the comparison of coordinate especially the ellipsoid height. I did 3 pillar on yesterday (minimum requirement) and result showed the differences in latitude and longitude were within 3cm and JUPEM circular 1/2008 under "Ujian cerapan statik berkala" 4.3.9 stated that the tolerance must less than 3cm in North/east and 6cm in height difference.

The three (3) pillars observation on yesterday showed that the difference ellipsoidal height more that 6cm. District Surveyor emphasized that the statement is on comparison between coordinate of epoch and not to the reference JUPEM coordinate. If we need actual height then we need to refer to geodesy department to get the geoid height "N" correction. It sounds positive to me but my friend measure from the marker to the top of screw and able to get tolerance result. I do not how to describe it!

How to plant mark with tripod

It is an easy task for most the cadastral surveyor and cadastral's mandore/labour. I just jot down this note because I believe in future, this method will be extinguished similar when I was in Sarawak in year 1996. Sarawak survey team were using jungle wood as reference point to replace prism in jungle survey. Thus, no people will be at the back to collect the RO. The survey labour just cut three (3) jungle woods and make like tripod. I remember they will sharpen one jungle wood and put in the center of this temporary tripod. The interesting part is the sharpen point will match with the station point. How to do it? Sorry, I do not know, Sarawak surveyor should able to share with us.

Tripod, tribrach and prism are the main components for this topic.

  1. The tripod should in good condition and the leg length is ease to adjust.
  2. The head of the tripod must flat for stability of the mounted prism.
  3. Impact of the stability of tripod very depending on each screw on the tripod.
  1. We are using tribrach with optical plummet in this case, even through there are tribrach with laser plummet or oldest tribrach used plumb line. Tribrach used plumb line is more easy to plant mark because we are able to position the point accurately but slower to set up.
  2. The three (3) screw of the tribrach must have bigger gap to move around when the head of the tripod is not flat especially tripod set at unstable area such like edge of the earth drain.
  3. It is an art of moving these three (3) screws of the tribrach. We are using two (2) hands. One hand is using 2 fingers and the others one is using 1 finger. There is a pattern for centering. These three fingers should move concurrently. The 2 fingers either move inward or outward and the other one finger should move up & down. See how the bubble move then adjust the screw accordingly.

  1. The prism has been calibrated
  2. Unloose prism is not advisable to use

How to set?
  1. Surveyor will give direction by open the bearing.
  2. Clear the observation line if there is obstruction such as leaf, grass, branch and etc.
  3. Mount the prism on top of tripod and get the approximate distance from surveyor.
  4. Move to the direction and surveyor need to tell the labour to move forward or backward by certain distance.
  5. Labour should know how long his foot. Normally Asian is 0.3meter. If the distance is 0.6 meter then the labour just move according to his length of his foot.
  6. Then set the tripod on the approximate point. The head of the tripod must as flat as possible. The approximate point can be marked with wood or any marker. This temporary point is the place where we need to dig and plant the boundary mark.
  7. Tread all three legs into the grass, bitumen, concrete or etc.
  8. One of the Tripod's leg must facing to theodolite. The purpose is to adjust the distance either backward or frontward.
  9. The other two leg are to adjust left & right.
  10. Look through the optical plummet and using the thumbscrews put the cross hairs back over the temporary point as mentioned on statement 6.
  11. Adjust the level of the tribrach by slackening the tripod screws and sliding the legs.
  12. Re-center the cross hairs using the thumb screws then fine tune the level using the the tripod legs.
  13. Once the tribrach is nearly centered over the temporary point, level the tribrach by using the thumbscrews.
  14. Slacken the tribrach from the tripod head and slide it the last 4-5mm so that it is centred over the approximate point and level.
  15. If the distance is within 10mm then we just adjust the tribrach. Else we need to adjust the tripod length. Distance more than 0.1 meter then you need to adjust back the temporary point as mentioned on statement 6. This is because the thumbscrews can not adjust up to 0.1meter.
  16. Always used leg lengths for centering and attempt minimum use of thumbscrews.

Cadastral survey is a not difficult task if you understand the concept behide of this survey. Even through lecturer in university or kolej tough this subject but most of the students can not merely understand how to apply in field work. JUPEM circular regarding cadastral is available but no many people can totally understand the content.

Academic is vital but cadastral surveyor can be trained if the person is wiling to learn especially those involved in cadastral survey. Yesterday, I read an encyclopedia regarding brain. There is no brainless human in this world. Some people can not afford to further their study due to many factors such as opportunity, financial, environment and etc. According to this encyclopedia, brain can be an useful weapon if we know how to utilize it with condition we need to polish it. It will be a “sharp weapon” if we polish it frequently. So, how to “polish” our brain? The answer is KNOWLEDGE.

When we are equipped with knowledge and explore to the real job, then subsequently we are gaining experience in field. Experience is the main “Guru” in any subject. There is no great/perfect “Guru” in cadastral survey. You need to master the cadastral survey start with how to set tripod. There is an art of setting tripod. Look simple but many young surveyors can not able to plant mark with tripod even in flat area. It is a nitty-gritty in presently. Once you have master the basic skill in land survey and understand concept of cadastral survey. By the time, you should able to know what is datum, baseline, refixation and relevant issue regarding cadastral survey. Cadastral survey will be a rice bowl for you and forever.

Common seal

This post is regarding the application of state land under “Jadual 1- Kanun Tanah Negara”. Even through the application have modern company seal and witnessed by commission of oat. It still do not fulfill the application requirement. Land office still requested the common seal. What is common seal?

Common seal also known as corporate seal or company seal. According to wikipedia,

“Traditionally, the common seal was of some legal significance because the affixing of the seal signified that the document was the act and deed of the company, whereas when a document was merely signed by a director, then that deemed to be an act carried out on behalf of the company by its agents, which was subject to applicable restrictions and limitation under the ordinary law of agency.

Common seal are generally only used for 2 (two) purposes by corporations today:-
  • Documents which need to to be executed as deeds (as opposed to simple contracts), may be executed under the company's common seal
  • Certain corporate documents, for example share certificates are often issued under the company seal (and some countries required that share certificates be issued under the common seal)”

The application was rejected and I immediately took action to solve it on the same day. Our client asked me to get the common seal from his company secretary. Initially, I wonder why the lady brought big staple for me. She just passed the common seal to me and I did not how to use it. Finally, the lady helped me. There is a handle for this common seal, we just press and the seal will leave impression on the paper. Usually, a red wafer is used to imitate old red seals, and to make the sealing show up better on photocopies which I can see in my license certificate.

The implementation of common seal on apply on company and no to personal application. Basically, we need below details to fill the form “Jadual 1”:-

  1. Company details
  2. Application plan
  3. Purpose of application
  4. Details of land, example : Mukim, location, area and etc

    Please take note that we need to attach with Form 24 & 49 and Company resolution which can be obtained from company secretary during submission.
