Topographic surveys and spatial data capture

A detail survey or feature and level survey can provide information about your site including features, level contours, structures, trees and services.  The cornerstone of quality data lies in a precise survey control network, and our proficiency covers a wide range, from small-scale surveys to large projects that require the coordination of multiple teams over significant distances. Quality survey data is available in various formats, including compliance with the SA Department of Infrastructure and Transport standards, for which we proudly stand as a preferred supplier.

Detail surveys can provide design-ready base map data for roads, rail, bridges, buildings, pipelines and housing or commercial allotments and can provide valuable information about underground services, ground topography and accurate spatial location of all features.  Final survey models comprise 2D or 3D strings, points and symbols in CAD format for import into design software or for production of detail survey plans.

Traditional detail surveys can be further enhanced with 3D scans and modelling, or aerial mapping for stunning background orthophoto imagery.

3D laser scanning is a revolutionary technology that allows for fast and accurate capture of complex environments and objects. With its ability to quickly and efficiently gather millions of data points, 3D laser scanning is becoming increasingly popular in a variety of industries, including engineering, architecture, construction, and manufacturing.

One of the biggest advantages of 3D laser scanning is its speed. Traditional surveying methods can be time-consuming and labor-intensive, but 3D laser scanning allows for the capture of large amounts of data in a fraction of the time. This makes it an ideal solution for projects where time is of the essence, such as in construction, where delays can be costly.

Our Trimble SX12 Scanning Total Station has an 800m range, and an accuracy of 2.5mm at 100m and produces beautifully clear data sets.  We also utilize the  amazing Riegl VZ-600i 3D scanner which records up to a million points per second for rapid data acquisition and mobile mapping applications.

After detailed 3D point cloud capture we are then able to create detailed 3D models for a number of different uses.  Some of the advantages of modelling a point cloud are:

• Much smaller files: point clouds are generally very large data sets, but once modelled the size reduces dramatically allowing greater portability and collaborative usage;

• Enhanced visualization: 3D models can be imported into BIM (Building Information Modelling) which enables enhanced visualization of a building or structure. The digital BIM model can be used to create detailed 3D renderings, animations, and virtual tours;

• Flexibility: once 3D models are created they can be easily read into a number of different software platforms and easily integrated with other data;

• Improved collaboration: 3D models allow for improved collaboration between different stakeholders, as the digital model can be accessed and shared by multiple parties involved in the design, construction, and maintenance of a building or structure;

Remotely Piloted Aircraft Systems (RPAS) have the advantage of being able to fly large areas in a short period of time which can save time and money on conventional methods which can take many times longer.  Our drone imagery can be processed to produce ground models and contours to typically 2cm accuracy, as well as beautiful geo-referenced orthophoto mosaics which can be overlaid in applications such as AutoCAD.  With our DJI Matrice 200 v2 we can cover a large area in a single visit (200ha) and can potentially operate in difficult, hazardous or completely inaccessible areas.  Applications can include:

• Digital terrain models

• Stockpile volumes

• Topographic surveys

• Pit volumes

• Environmental monitoring

• Project timeline photos

• 3D models extraction

• Geo-referenced orthomosaic maps

• Point clouds

• Asset management for council and rural applications
