Free station This method makes possible obtaining coordinates of a free station based on targeted points from this station towards other stations or towards known points in coordinates. A step by step assistance. Features natively included into our software. This method calculates coordinates of each of taken points from a known point, called P1. Interactivity on the drawing.
This known station should be positioned or previously calculated. This method involves positioning a serie of aligned stations on a known base.
There is no overall compensation in real time on the topographical survey. Thus, our software can calculate the coordinates of all stations by compensating distances.
The use of a topometric calculation is therefore, in some cases, necessary to compensate for the entire topographical survey. Calculation of targeted points This method allows to calculate coordinates of all the targeted points from a station.
Elevation This method calculates coordinates of each of taken points from a known point, called P1. The plan is then projected in 2D. In addition, other calculations methods can be used: Calculated points by intersection This method involves targeting the same point in angles from several stations.

Opened traverse This method involves describing an opened traverse from a known station in coordinates. It is an all-in-one solution: Geodetic projection This method changes the geodetic projection system of any topographical survey. Helmert transformation With ou without scaling, this method results topometriqufs changing a coordinates system to a set of selected targeted points.
Topometric calculations From the field to the office! This method makes possible obtaining coordinates of a free station based on targeted points from this station towards other stations or towards known points in coordinates.

Aligned stations This method involves positioning a calcups of aligned stations on a known base. This method involves describing an opened traverse from a known station in coordinates. In addition, other calculations methods can be used:. As your movings progress, our software calculates your different positions. With ou without scaling, this method results in changing a coordinates system to a set calckls selected targeted points.
Retouching a station This method involves setting up again a previously existing station. Calculation is done by difference of vertical angles on the vertical straight line passing through the P1 point.
