We strive to be pioneers and thus leaders, in our spatial science profession. Our team consists of skilled and qualified professionals with many years of experience.
We utilise the latest technology to service all projects large or small and continually research new solutions to achieve the highest quality results.
Land Surveys conventional survey instruments consist of either Leica TS15 series or Leica TS16 total stations. All total stations are equipped with automatic target recognition; this ensures accuracy and elimination of human error in pointing.
Total stations are calibrated on a regular basis using the calibration software installed on all Leica total stations. This includes calibrations for horizontal collimation, vertical index error, ATR (automatic target recognition) alignment.
Land Surveys uses Leica DNA or Sprinter digital bar code reading levels for accuracy, and elimination of human error in staff reading. Digital automatic levels are regularly checked and adjusted for collimation error prior to any level traverse undertaken on a weekly basis if used regularly.
At the start and end of each day, the GNSS Rover is to be checked onto a fixed control point to determine positional difference in easting, northing, and RL.
We use Liscad and/or 12D Model surveying and engineering software for computations, transformations, uploading and downloading information from total stations, GNSS and digital level, least squares adjustments of observations, importing and exporting digital information to and from other packages, modelling 3D surfaces and calculating volumes.
Briscad and Autocad are used for drafting and interrogations of DWG or DXF data received from clients.
ASCII point files can be extracted from all of Land Surveys Software programs on request.
We focus on capturing accurate, high precision, 360-degree imaging with the use of our iSTAR Pulsar technology. This device enables our team to capture high resolution, georeferenced, spherical imagery; to provide clients with an unbiased record of their project’s condition at a fraction of the time.
This georeferenced, spherical imagery can be captured at traffic and walking speed, at various intervals along the road corridor. Therefore, traffic management and road closures are not required.
3D laser scanning is rapidly becoming the preferred survey method for measuring complex objects or structures. Scanning provides our clients with a fast, safe and cost-effective alternative to traditional survey methods.
This technology is particularly beneficial when plans of an object or structure are not reliable or unavailable; the 3D laser scanning provides are a rapid, accurate way to measure any object ranging in size from a few centimetres to hundreds of metres in size. We utilise the latest high resolution terrestrial 3D laser scanners run by experienced field staff.
For mining projects, we use a Riegl laser scanner; it has exceptionally long range allowing Surveyors to remain a safe distance from potentially hazardous areas such as pit walls. For smaller scale projects, we use a Faro Focus 3D scanner. It is fast, very portable and produces full colour 3D scans.
In industry best rail-service monitoring and analysis Land Surveys is deploying the use of track-mounted “clever” trolleys on a range of transport networks. While manual labour is still needed, detailed computer based automated data capture and analysis flowing from trolley computer monitoring is consistently emerging as faster, labour-saving and more economical.
The use and standard of trolleys must be – and for Land Surveys has been – approved by TfNSW and Sydney Trains. Australian Engineering Organisation Framework status under the aegis of TfNSW is also required to undertake the trolley surveying works in the State. For safety purposes, all surveying takes place on closed sections of track.
Our custom-built RC hydro boat is the perfect way to acquire a complete surface model of water & land-based assets.
Our custom-built RC hydro boat (Bathymetric) capabilities include reading depths from 0.4m up to 180m and a run time of 4 hours before changing batteries. Our RC boat runs a twin jet propulsion system which enables 360° pivot on the boats axis unlike propeller systems that require the skipper to steer in a circle to change direction. The jet propulsion is also a safer solution as there are no external moving parts like propellers and it is less likely to be caught on any submerged objects.
