In Xirio, the user can perform radioelectric calculations at high resolution, thus obtaining a result of high quality and precision. To do this, it is necessary to select the option "High resolution calculation" from the action window.

When the user performs high-resolution radioelectric calculations, Xirio informs about the price in euros that entails the operation in progress. Once the calculation is finished, these euros will be deducted from your account.

The user can consult always the euros balance in his account and carry out the purchase of new credit as well.

This total cost is obtained as the sum of:

•Cost of study. Calculated depending on the pixels number involved in the calculation,ie the larger the calculation area or the distance between transmitter and receiver, the higher the cost. Therefore, it is important to select only area where results are required. In case the transmitter is outside the calculation area, it will be computed in this cost all the pixels that should be taken into account from the transmitter to the calculation area.

•Cost increase for cartography. Obtained as a percentage increase on the study cost. The increase depends on the provider of cartography and the quality of this.

In addition to obtaining a high quality result, when performing a payment calculation on Xirio, the user is also entitled to:

•Results storage of this calculation for one month on the platform Xirio. This period of time is extendable through an increase in cost by selecting the option extend hosting of the results.

•Download results to the user's computer. The available download formats are KMZ (Google Earth format) or GeoTIFF format (standard cartographic format valid for most of commercial GIS).

•Share the result of this calculation with a maximum of 10 users, through its publication.

COST OF CALCULATIONS

The calculations price is obtained according to pixels involved in this, so this cost is directly related to the selected resolution. The user can modify the resolution before confirming the calculation. When selecting any other element on the dialog the cost of the study will be updated.

COST OF CARTOGRAPHY

There are available many cartography layers on Xirio that the user can use in their calculations. Depending on the cartography provider and the layer quality, the use of cartography will entail an increase on the calculation cost.

The dialog shows the cartography layers selected by the user. The column "Cost" indicates the cost increase of using each cartography layer. From this dialog it is possible to modify cartography to be used in the calculation, thus updating the cartography cost.

COST OF HOSTING

Xirio keeps the payment results for one month on the user's account. It's possible to extend the storage time for a quarter, half or a full year.

•A quarter: 10% of the calculation cost (excluding the increase due to cartography).

•A half: 20% of the calculation cost (excluding the increase due to cartography).

•A full year: 35% of the calculation cost (excluding the increase due to cartography).

In order to renew a result hosting, Xirio will notify the user, by email, several days before the expiration date. If the renewal does not take place, the expired results will be erased.
