Elevation This method calculates coordinates of each of taken points from a known point, called P1. In addition, other calculations methods can be used:.

### Topometric calculations – Géopixel : Géopixel

With ou without scaling, this method results in changing a coordinates system to a set of selected topoetriques points. The plan is then projected in 2D. This method involves describing an opened traverse from a known station in coordinates.

Calculation is done by difference of vertical angles on the vertical straight line passing through the P1 point. As your movings progress, our software calculates your different positions.

## Topometric calculations

This method involves positioning a serie of aligned stations on a known base. Calculation of targeted points This method allows to calculate coordinates of all the targeted points from a 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.

The use of a topometric calculation is therefore, in some cases, necessary to compensate for the entire topographical survey. Interactivity on the drawing. Retouching a station This method involves setting up again a previously existing station.

In addition, other calculations methods can be used: This known station should be positioned or previously calculated. This method calculates coordinates of each of taken points from a known point, called P1. Features natively included into our software.

A step by step assistance. Geodetic projection This method changes the geodetic projection system of any topographical survey. Thus, our software can calculate the coordinates of all stations by compensating distances. Aligned stations This method involves positioning a serie of aligned stations on a known base. Opened traverse This method involves describing an opened traverse from a known station toplmetriques coordinates.

Helmert transformation With ou without scaling, this method results in changing a coordinates system to a set of selected targeted points. Topometric calculations From the field to the office! Calculated points by intersection This method involves targeting the same point in angles from several stations.

There is no overall compensation in real time on the topographical survey. It is an all-in-one solution: 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.
