Field

Field

Field is an add-on module included in the base module, for connection to certain instruments, total stations, and GPS instrument directly into the drawing. The Field module makes it possible to follow the position directly in the drawing and mark points for survey and stake out.  

Instrument

Select instrument under Settings in Topocad.ini. Choose between total stations Topcon AP-L1 and Geodimeter ATS series. For more information regarding settings for each instrument please contact Adtollo AB. The settings are different for different instruments.

Road line

Usage of road line as reference. Section and offset are displayed continuously.  

GPS

When having a GPS instrument, TopGPS is used as a software system between the GPS instrument and Topocad. This software system can transform co-ordinates interactive and Topocad reads the data directly. No more instrument connection is necessary. Please contact Adtollo AB for further information regarding TopGPS.

Standard (GGA)

Standard (GGA) sets the position in geodetical co-ordinates (latitude, longitude and ellipsoid height). Get the geocentric co-ordinates by transformation via Gtrans to an appropriate co-ordinate system.
