Laser Scanning has opened up a new dimension within data capturing that enables accurate and efficient surveying. Though still a rather new technique, laser scanners are now being used more widely in the process of surveying due to the accuracy of the results they provide Shivam Surveying System have recently launched the additional service of carrying out Laser Scanning Surveys using the laser scanning instrument. The company is now able to carry out High Definition Surveying, using this very fast pulsed laser system.
With the inclusion of this new technology we try to produce the best possible drawings & data to our clients.Our surveyors have considerable experience of surveying detailed ornamental building façades, and complex internal structures; particularly of historic buildings.The company has taken advantage of the latest Laser Scanning technology, which is of considerable help when carrying out architectural surveys. However in addition to this, this equipment has numerous other possible applications where 3D position / points need to be recorded, for example; archaeological surveys, complex mechanical installations, GIS / Asset Management, and general site topography.
The Leica Scan Station 2, can produce a 360° three dimensional “point-cloud” of survey information, which is of particular assistance when capturing data in areas of intricate detail. The system also incorporates a high resolution digital camera. Using specialist “Cyclone” software, the data can be used to produce rendered 3D “models”, and areas can be selected as required for detailed drawing production. One advantage of using this equipment is that the area to be surveyed can be comprehensively scanned whilst on-site, and the data can then be stored in an “Asset Database”; with only the immediate requirements being developed into finished drawings. Further areas can be processed into drawings as and when required, at a later date without the need for a further site visit, (assuming the area in question remains unchanged on site; otherwise a site update would be required).
This could be of particular interest to clients with a large portfolio of sites, where a database of assets is required. But, rather than surveying all the sites in detail at once, (which would be time consuming and costly), the initial task of scanning the sites could be undertaken; with specific elements developed into drawings as and when required.Similarly, if for example, an historic building was being restored / renovated, the whole building could be scanned, and the “point cloud” stored in a database for later use. Then as specific areas of interest were identified, these areas could be developed into floor plans, elevation, or section drawings, as required. This could be helpful with regard to project costings and budget.Typically, traditional linework drawings in AutoCAD DWG or DXF format are provided, although other export options are also available.The equipment is also useful in capturing a large amount of data quickly, (up to 50,000 pts/sec). This is of benefit where a geospatial record is required, but where available site access time is limited. One recent example, was the laser scanning of sea defences; which was carried out in the time available between tides.
