Jones, Simon (2010) Stop-go mobile mapping. [USQ Project]
[Abstract]: The surveying profession has seen many advances in the way that data is captured in the field. Recent years have seen the development of Terrestrial Laser Scanners (TLS) that have offered an alternative to traditional survey techniques. TLS are an automated high speed data capturing device, which can have a reflectance range of upwards of 1000m, making them especially useful for locating terrain in often inaccessible areas.
Within a mine site, TLS have been used for large scale DTM’s (pit shells). In these circumstances, surveyors have often put themselves at risk to obtain the best vantage point. Tops of bund, edge of high-walls, edge of low-walls and even pit ramps have been used. For this reason, this dissertation examines a TLS, whilst mounted to a Caterpillar all-terrain loader. This combination (TLS and CAT loader) was designed to enable a safer and more efficient way of capturing data.
To enable all of the field work to be performed within the cabin of the machine, stop-go mobile mapping uses an advanced method of registration. A simple, short backsight location (mounted to the machine) is all that is required in the field.
The registration process requires the use of a Multi-Station Adjustment (MSA) and it is these parameters that are determined from the results of this project. Finally, the accuracies of the data will also be tested and this will determine whether the MSA has worked effectively.
