Improved Self-levelling Lasers

Pentax (Japan) has introduced improved self-levelling lasers. The PLP-700 Series replaces the existing PLP-600 Series and comes with some technical improvements as well as a major move forward in design. The PLP-700 Series improves the height accuracy of the detector from ± 1mm (LS-6) to ± 0.7mm (LS-7) and increases the measuring range from 0.5m-200m to 1m-200m (PLP-600). Identical to the PLP-600 Series, the PLP-700 Series comprises 4 models: PLP-701, PLP-701R, PLP-702 and PLP-702R. The new design of the PLP-700 Series is part of the recently launched new product strategy where a new, identifying product colour scheme has been set.... (read more)

Levelling the GI Playing Field

ISO/TC 211 Geographic Information Standards
For the past ten years, the International Organization for Standardization (ISO) Technical Committee 211, Geographic information/Geomatics has been working on standards development. It is now completing an initial set of twenty integrated standards and has already begun work on a second set, to include standards for imagery and location-based services. Unlike previous ISO technical committees, ISO/TC 211 has the unique distinction of beginning and continuing a programme of work focused on the concurrent development of integrated sets of standards for geographic information. The ISO/TC 211 website provides listings of approved standards, an overview of each, and current work items. While... (read more)

Total Station for Aircraft Levelling

One of the world’s most successful military training aircraft, the PZL-130 TC Orlik manufactured by EADS PZL Warszawa-Okecie S.A., Poland, is now being levelled with the aid of a Nikon Nivo 5M total station. Aircraft levelling, both longitudinally (forward and aft) and laterally (left to right), is performed in the final stages of assembly. Accurate levelling of the aircraft on the ground is required before precise alignment and symmetry checks can be performed to confirm that the geometry of the aircraft is to specification. Prior to using the Nikon Nivo total station, levelling was accomplished with a theodolite and precision... (read more)

Re-surveying Firms for Levelling after Earthquake

Following a competitive tender process, Land Information New Zealand (LINZ) has appointed Opus, Beca, and CPG to carry out critical re-surveying work in post-quake Canterbury. The three firms will share the significant task of restoring the region\'svertical control network - the system of about 400 survey markers that enable the accurate determination of heights. The work is expected to be completed by June 2011. Government recently gave LINZ an additional NZD850,000 towards this and other earthquake-related surveys in order to discover how the position of the land has changed - information that is critical as the region's infrastructure is re-established."We...

Land Subsidence in Urban Areas of Indonesia

Suitability of Levelling, GPS and INSAR for Monitoring
Excessive groundwater extraction is probably the main factor causing land subsidence in urban areas of Indonesia. Decreases in groundwater level may reach 15 metres a year. Monitoring of land subsidence in suspected cities is required for groundwater extraction regulation, effective flood control and seawater intrusion, conservation of environment, construction of infrastructure, and spatial development planning in general. The author treats the capabilities and constraints of levelling, GPS and INSAR for monitoring land subsidence in Jakarta, Bandung and Semarang. The relatively large urban areas of Indonesia usually have dense housing, building and/or vegetation (Figure 1). Land subsidence in urban areas may... (read more)

Leica Sprinter 50, 150/150M and 250M

Leica Geosystems (Switzerland) has introduced the Leica Sprinter 50, the one-button electronic level, and the Leica Sprinter 150/150M and 250M for advanced leveling. The Leica Sprinter 50 is a levelling tool for daily tasks and basic work on the construction site. The user aims, focuses, and measures by pressing one single button. The data is displayed almost instantly. Misreadings are eliminated, and error reducing functions, such as the tilt sensor, prevent the system from measuring if the user operates outside the compensator range. The accuracy is 2.0 mm deviation per 1 km double run.   For more complex construction tasks,... (read more)

Sokkia LP310 Leveling Laser

Sokkia (Japan) has extended its construction laser range with the introduction of the LP310 Leveling Laser. The LP310 is a self-levelling construction laser designed for long-range tasks, up to 600m in diameter, with an accuracy of 10 arc seconds. The laser class is Class 1 invisible laser. The LP310 is conforming to the IP55 environment protection standard (IEC60529) and offers resistance to dust and water-resistance sufficient to withstand a sudden downpour. LP310’s self-levelling range is a remarkable +/-4 degrees making for smoother, more efficient setup. The 'H.I. Alert' function makes the laser beam shut off when the instrument is tilted...

Sokkia Releases Triax LT40 Cross Line Laser

Sokkia BV (The Netherlands) has introduced the LT40, a compact cross line laser for inside and outside jobs. The LT40 is a new and versatile tool and replaces the former Triax LT50. With just one ‘line’ button users can cycle their operation. The LT40 users can use a horizontal line, vertical line or laser cross, plumb up and down. The LT40 is a suitable tool for the smaller companies especially for finishing specific construction jobs, for example to level and plumb decks, framing and partition walls, plumb window and door frames. Other applications like levelling and setting cabinets and counter... (read more)
