Topography


Topography and Cadastre solution it's a powerful and complete tool for survey processing, simple in its tabular interface and quick in its graphic managing. This solution is made for tri-dimensional elaboration and for bi-dimensional cadastral surveys handling; it allows to manage several surveys and topographic points group in the same drawing, so that it is possible to follow the developments of a building site.

Brief description

It’s used by technicians who are interested in topographic surveys for civil engineering planning and constructing, for cadastral insertions and monographs...

Features:

  • no limits on the number of points
  • automatic labelling of a points group by code, description
  • computation of any kind of survey (celerimetric, GPS, levelling, cadastral...)
  • managing of more point groups
  • calculation of profiles and cross sections
  • import/export from any data collector
  • automatic creation of breaklines (gradings, roads..) and cadastral units

Topographic instrument handling

It's provided, with related distance and angle errors. It is also possible to associate to each station a different instrument with different instrumental errors. The following functions are included: re-calculation of Azimuth angle subsequent to changes of station orientation;
Observations input handles indifferently details, restriction points, orientations, traverse points, without inserting particular codes for calculation.
The drawing can be handled as a 3D or a 2D drawing keeping unaltered elevations information, essential to model elaborating.

Field-book handling

Field-book can be acquired from files directly downloaded from data collectors or stations (through the Transfer software, freeware available on this site in the Download area) and it is then handled through simple and intuitive dialog-boxes which allow insertion and change of stations, observations, linings and surveyor crosses.
Data are automatically re-calculated in order to be handled both as vertical angles and slope distances and as elevation differences and reduced/horizontal distances.

Computation

The adopted computation algorithm is flexible and powerful. With the aggregate solution method the survey is processed considering multiple stations, ground openings and closures, orientations to points from different stations, simple and multiple frontward and backward intersections, distances intersections; all this without inserting particular codes to distinguish orientations, traverses, and so forth…
With disaggregated calculation traverses hierarchy is respected.
Elevations elaboration can be excluded or integrated with trigonometric or geometric levelling. Computation can be performed with or without compensation, which can be intrinsic or extrinsic, empirical or rigorous to the least squares: with rigorous compensation it is possible to establish required precision and the maximum number of interactions.
Any rough mistake can be detected by adjustment deviation.

Field-book updating

Insertion in cartographic plan or in known points scheme can be made through the use of constraint, through rigid rototranslation on the points of higher reliability, with further reduction of errors to the least squares without change of scale or with anisotropic or isotropic change of scale.
Corrections for refraction, globe curvature and cartographic projection can be applied. Coordinates can be expressed on a local sphere (the radius is calculated by the program, once the ellipsoid has been selected) or in a 3D reference with x,y plane tangent to a provided point.
The program allows to obtain a complete account of the computation performed: approximate coordinates and adjusted coordinates with the indication of root mean square deviations and of co-variants, the root mean square deviation, differences and distances between deviations between known points of the survey.
It is possible to edit attributes of computed points, add new points (indicating also the station from which they have been surveyed) and obtain field-book updating.
Automatic generation of a new field-book, useful in case of mark-out, can be obtained starting from coordinates and individuating one or more traverse vertices.
