LTOP

LTOP allows pre-analysis and compensation of polygon networks, triangulation networks, combinations of GNSS observations and terrestrial measurements as well as levelling networks. 

Pre-analysis and adjustment software for geodetic networks

LTOP offers several computing facilities and indicators in order to optimise the compensation and detect errors or inaccuracies. The observations can be adjusted by the smallest squares or the robust method.

A new graphical interface has been integrated into GeoSuite, which significantly simplifies the input of parameters for an LTOP calculation.

Possibilities and properties

• Horizontal and vertical adjustments are processed separately (2D+1D)
• Free adjustment, coordinates of the connection points as observations or constraint adjustment
• Calculations based on projected or ellipsoidal coordinates
• For directions, azimuths and distances, up to 80 groups can be defined with individual unknowns of orientation, scale or offset: a-z A-Z 0-9 ! # $ % & * : ; < = > ? @ _ | ~ + -
• Several possible parameter calculations for the integration of GNSS observations
• Strict treatment of accuracy and reliability parameters and required tests for use in the Swiss cadastral survey
