All sorts of free low-resolution calculations can be done using the Planning Tools Application of Xirio Online. The type of calculations are perfect for non profesional results or for adjusting the station parameters before making a pay calculation. These calculations have a number of limitations:

- Limiting of the calculation resolution depending on mapping used.

- Storage of the calculation results in Xirio Online platform for three days, keeping only the last calculation.

To perform a free calculation the user must select the option Free low-resolution calculation from the actions panel.

The window that appears informs about the resolution and the mapping layers to be used in the calculations.

The MFR column (Maximum free resolution) indicates the maximum resolution allowed for the calculation of the free study for each of the mapping layers. In the case of using several mapping layers the greatest of these values will be taken.

As performing payment calculations, the user can modify the cartography to be used from this dialogue, updating by this way the resolution of the study.
