Poll

Are you considering working with an UAV for surveying?

I already use UAVs (please share your experience in the comments)

I'm orienting to invest in UAVs

I'm not sure yet

No, I will not use UAVs (why not? Please comment)

High-end Total Stations

25/01/2006

Compared to the 2004 product survey on total stations, this new survey includes some newly introduced and some upgraded and/or restyled existent models. The expected total station integrated with GPS or digital camera has not yet arrived.

Henk Key, contributing editor, GIM International

In 2004 FOIF and South were introduced as new manufacturers. Then they seemed to represent the frontrunners of Asian and Russian companies entering the market for High-end Total Stations. However, up to now no additional newcomers have joined the club. South and FOIF have both extended their range of instruments.

Integration
The integration of GPS technology and total station has not yet made the expected breakthrough. Leica’s solution with top-mounted GPS receiver is a software match but the true integrated GPS Total Station still has to make its entry. The same is true for the integrated digital camera. Topcon is the only firm offering such a device; one that would seem to have much potential, both photogrammetric applications and to support the processing operator in the office by providing pictures of the survey site.

Miniaturisation
Trimble has successfully restyled its instruments; they look good and are easy to handle. Although so many technological developments are associated with the keyword ‘miniaturisation’ (look at cellular phones), surveyors are still struggling with giant instruments. Miniaturisation would also enable the use of lighter tripods, which further reduces weight, making the life of the land surveyor a whole lot easier. Does miniaturisation somehow lie below the challenge horizon of designers of surveying equipment?

3D Scanning of Historic Sugar Factories

The Alliance for Integrated Spatial Technologies at the University of South Florida, USA, recently worked with the Florida Park Service on a project to document the remains of several historic sugar-mill sites in the State Parks to create as-builts to be used in preservation and conservation of these resources. The FARO LS 880, along with GPS and total station georeferencing and colour imaging, was used on these projects.
