Topcon AP-L1A Robotic Total Station

The Total Station, which consolidates precise angular and distance measurement into a single compact instrument, has been the industry standard since the late 1980's. The next step in the evolution of survey instruments is the Robotic Total Station, which allows for remote control of all instrument functions through a radio link. Measurement data is transmitted to the data collector (see below) via the radio for storage.

 

With robotic capabilities, one man can match, or exceed the productivity of a conventional two or even three man survey crew. Conventionally, the least trained crew member often manned the "rod", collecting the survey data. In Bristol, Sweet & Associates' one-man field crew with the robotic instrument, all information is gathered by a licensed land surveyor. We were one of the first in the state to utilize this new technology, having been the first in New Hampshire to purchase a Topcon AP-L1A Robotic Total Station in March of 1999.  

 
TDS Ranger Electronic Data Collector

This is a small, rugged, handheld computer (running on a DOS platform) containing software that electronically records all measurement data, thereby eliminating transcription errors, and increasing the efficiency of the field crew. The data is downloaded directly into the office computers, saving still more time. The software allows  complex mathematical processing to be performed in the field, and provides many routines to aid in operations such as setting lot corners, staking out roads and establishing horizontal and vertical survey control points. Control of the Robotic Total Station is integrated with all these functions. 

 
AutoCAD, Version 14 & Softdesk, Version 8

AutoCAD is a  computer aided drawing/drafting program. Softdesk is a surveying, and civil engineering program running within AutoCAD. These programs are the industry standard. We began running AutoCAD in 1985 and have customized AutoCAD & Softdesk, writing programs to run them more efficiently for us. Softdesk allows for the electronically stored  field notebooks to be downloaded from the data collector directly to AutoCAD, thus eliminating transcription errors, and increasing efficiency.
