Geodetic projection This method changes the geodetic projection system of any topographical survey.

This method involves describing an opened traverse from a known station in coordinates. Topometric calculations From the field to the claculs It is an all-in-one solution: This method involves positioning a serie of aligned stations on a known base.

Topometric calculations

Helmert transformation With ou without scaling, this method results in changing a coordinates system to a set of selected targeted points. Interactivity on the drawing. A step by step assistance.

In addition, other calculations methods can be used: Aligned stations This method involves positioning a serie of aligned stations on a known base. In addition, other calculations methods can be used:.

This known station should be positioned or previously calculated. Retouching a station This method involves setting up again a previously existing station.

Calculation of targeted points This method allows to calculate coordinates of all the targeted points from a station. 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.

Features natively included into our software. Calculated points by intersection This method involves targeting the same point in angles from several stations.

The use of a topometric calculation is therefore, in some cases, necessary to compensate for the entire topographical survey. There is no overall compensation in real time on the topographical survey.

Opened traverse This method involves describing an opened traverse from a known station in coordinates. This method calculates coordinates of each of taken points from a known point, called P1.

With ou without scaling, this method results in changing a coordinates system to a set of selected targeted points. The plan is then projected in 2D.

Thus, our software can calculate the coordinates of all stations by compensating distances. Elevation This method calculates coordinates of each of taken points from a known point, called P1. Calculation is done by difference of vertical angles on the vertical straight line passing through the P1 point.

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. As your movings progress, our software calculates your different positions.
