After several months using a pre-production Topcon GLS-2000 laser scanner, we now have a full production model and have used it on a couple of medium-sized projects already, as well as some interesting tests. As the hardware for collecting large clouds of point data become more and more similar, the focus (pardon the pun) is…
Cardiff Bay is a great place to capture a wide variety of historic and modern buildings. We’ve used this as a test for all our scanning hardware, so started off with the Pierhead Building. This was built in 1897 as the headquarters for the Bute Dock Company and remains one of the most spectacular structures in…
Laser scanning involves the collection of millions of accurate points from a single scan position. By ‘conventional surveying’ we refer to total station (TS) or GPS surveys where typically one or two operators are required to record individual points. Some of the advantages – from our point of view – of the scanning technique (also…

The Topcon GLS-1000 scanner has the facility to undertake “detailed” scan. In this mode, it repeats the data acquisition within the specified scan area two or three times. The final dataset will contain only…
