Systra - Geometrical Integration of Heterogenous GIS Data

Systra is an adjustment program for the geometrical integration of heterogeneous GIS data by interconnected transformation and homogenization.

The adjustment algorithm processes beside the coordinates to be transformed also geometrical constraints and geodetic measurements. The calculation kernel Systra which also gives the name to the program system is complemented with different modules with graphical user interface.

SystraShell - Project Administration

  • Input and modification of control parametres

Systra - Adjustment Kernel

  • Adjustment by the least squares method
  • Statistical analysis
  • Homogenization
  • Logging of results

SysPlan - Graphical Analysis

  • Observations
  • Line geometry
  • Translation vectors
  • Normalized residuals
  • Parts of redundancy

SysMatch - Matching

  • Identification of identical objects by matching of points, lines and corners
  • Generation of inentity observations
  • Finding of geometrical constraints amongst others rectangularity, rectlinearity and parallelism
  • Generation of geometrical constraint observations

SysGed - Graphical Editor

  • Graphically interactive data manipulation
  • Display, manipulation or manual acquisition of measured values and geometrical constraints
