Underground Utility Mapping


Frequently Asked Questions:

Q: Why do I need an underground utility detection (UUD) survey ?
A: It allows you to find out whats buried without any digging. This non-invasive method of detection is crucial in avoiding costly damages to assets or injuries/loss of life during 'blind' excavations.

Q: Is it really necessary ?
A: Local authority of certain high-density areas (e.g. Kuala Lumpur, Penang and Johor Bahru) may require UUD data to be submitted as part of the as-built survey in the application for a Development Order (DO). A recent customer inquiry involving a factory development in Subang shows that other municipal councils are imposing similar requirements.

Q: Can Jurukur Perunding do a UUD survey ?
A: Several JUPEM guidelines are evident of such work being undertaken by land surveyors. Work undertaken by our company can be endorsed by one of our licensed land surveyors.

Q: What can you detect ?
A: We can typically propose suitable methods of acquiring non-intrusive information on buried structures (up to a depth of about 10 feet) using a combination of equipment such as electromagnetic locators and ground penetrating radar. Things we can detect include:-
  • Metal objects ( e.g., pipes, tanks )
  • Asphalt thickness ( layer of road surface material )
  • Water body ( e.g., leaks and water table )
  • Non-metallic objects ( suitable cables using flexi-trace )
The timing of survey is crucial (for example, high water content during the monsoon season will affect the results).

IFSAR/NEXTMap Malaysia Data Set covering Peninsular Malaysia and Sabah

As mentioned in the earlier postings, JPSurveys is the appointed reseller to promote the IFSAR data captured by Intermap under the NEXTMap@ Malaysia project. It is our pleasure to introduce the different core products to the Malaysian market.

Year of acquisiton: 2008-2009
The country-wide data set consists of the following three core products:

Orthorectified R
adar Images (ORI)

ORIs look somewhat like monochromatic aerial photos. They are radar images acquired by the IFSAR sensor. Pixel size of 0.625m (Peninsular Malaysia) and 1.25m (Sabah)



Digital Surface Model (DSM)


Elevation Model that displays the elevation of the first surface on the ground that the radar signal strikes. Elevation at 5m posting and accuracy of 1m r.m.s.e.




Digital Terrain Model (DTM)

DSMs are used to create DTMs by digitally removing the elevations of cultural features and tree areas. DTMs are useful for application where an accurate sense of the underlying terrain is required. Suitable for generation of 5m contour lines.


The data set is very
suitable for the following applications: -
  • Contour/terrain map, profile generation, volume calculation
  • Slope map, line of sights study, hydrology study
  • 3D visualization, fly through, flight simulation
  • Feature extraction, base mapping, topographical, land use analysis
  • Image orthorectification, satellite image map
  • Flood risk map, watershed analysis
  • Geological map, precision farming, forestry
  • Many more....

Gogopal M38 Personal Navigation Device

Stress-free Driving with Gogopal ...
To recap, Jurukur Perunding Services Sdn Bhd is appointed as a reseller for the Gogopal M38 Personal Navigation Device (PND) since 2005.


People on the move (e.g., real estate agents, insurers and loss adjustors) in new unfamiliar places may find this PND quite useful. Some of our project managers managed even to locate hard-to-find outstation sites using this device whose plus points include:-
  • Accurate navigational road maps done by a Malaysian company (MapIT) - the people who knows the road best (provider of Google Maps map data)
  • 'Wah good' coverage - more than 75,000 km of Malaysian roads for almost all major (and minor) towns in West Malaysia, Singapore (and soon, Brunei Darussalem)
  • Reliable voice prompt
  • Turn-by-turn navigation capability
  • Quick recomputation (of alternative routes)
Its other capabilities also include video player, MP3 and photo viewer. Inquires should be directed to our sales personnel.

ISO 9001:2000 Certification


Jurukur Perunding Services Sdn Bhd (and Jurukur Perunding World Service Sdn Bhd) received their ISO 9001:2000 certificate on 1st August 2003 from SIRIM QAS Sdn Bhd. The scope of services includes:- 1) provision of land, hydrographic surveying and aerial mapping services; and 2) provision of geographical information system (GIS), remote sensing (RS) and geomatic services.

We are the first Malaysian land survey company to have achieved multi-site certifications (i.e. separately for our headquarters in Selangor and branches in Penang, Kedah and Melaka, respectively). Reciprocal certification from the Swiss-based IQNet Association was also obtained. Management wishes to express its appreciation to its advisor, Dr Loo Koi Sang, for his continual support and guidance.

Feedback regarding quality issues can be directed to our Quality Management Unit (QMU). Efforts in upgrading to the ISO 9001:2008 Standard is in progress. (JC/E)

Product Sales & Technical Training: IFSAR/NEXTMap Malaysia

We are appointed as an authorised reseller of IFSAR products in Malaysia. A Sales and Technical Training was conducted on 5 March 2009 at JPSurveys' Head Office in Puchong, Selangor by technical experts (Mr. Jan Schoderer and Mr. Ian Seeton) from InterMap Technologies . InterMap Technologies is a US-based company that serves a growing Digital Elevation Model (DEM), Geographic Information Systems (GIS) and Geospatial marketplace. More than 20 of our employees (ranging from top management to production staff) attended the event. The Vice-President of Credent Technologies, Mr. Lee Sze Keong, was also present.

The objective of this training is to enhance our technical knowledge on IFSAR (NEXTMap) data products availability for Malaysia. The country-wide data set consists of Orthorectified Radar Image (ORI), 5-m posting Digital Surface Model (DSM) and 5-m posting Digital Terrain Model (DTM). This was held in conjunction with the expected release of NEXTMap Malaysia product (tentatively scheduled for May 2009). An array of possible value-added products that JPSurveys can create specifically for the Malaysian user community (primarily comprising engineers, planners, and local government departments) using this data set was explored.

For more information on IFSAR products, please feel free to contact our Mapping Division. (E/W/J)

RTK Just Want to Have Fun



There have been reports that we are confining our lady surveyors to the office. This is not entirely true! To show that we are not gender-biased in our company, the all-girl teams are being sent to some outstation sites located around West Malaysia ( re: CCI ) and Brunei Darussalem for their field assignments.


Do feel free to contact us in the Engineering Surveys Division if you need more information on RTK or GPS work. (jc)

Aerial Photographic Products



This is our proven cost-effective method of acquiring reliable 2-dimension and 3-dimension spatial information. We take photographs from airplanes or helicopters. Such photos provide a visual evidence of the existing features at a particular point in time.

Other related products that can be derived include digital line maps, digital terrain models (DTM) and orthophoto mosaics. The maps can be produced within the scales of 1:2,000 to 1:10,000 depending on the flying height of the plane or helicopter. Some uses of the products are:-
  • Preliminary route planning and design
  • Asset management
  • Computations (e.g., slope analysis, cut-n-fill and volumetric calculation)
  • Map updating and GIS applications
There are also the options to buy existing (archived) photographs or acquire new ones from other sources. Contact us if you are interested in this service.

3D Terrain Visualisation



We are able to generate perspective views and virtual fly-thru to give you an unparallel insight of your project site. This data is especially useful for:-

  • Infrastructure development (e.g., highway selection and planning purposes)
  • Town and country planning
  • Real estate (or township) development
  • Other Geographical Information System (GIS) usage
Value-aided information may include overlays of land parcel information, administrative boundaries, computer-rendered building blocks and photo-realistic rendering.
