Resource Calculation Service
============================

The service CalcResourceService gives you access to generate resource maps in windPRO
The service itself if relatively simple with the ``CalcResourceService.GetResourceCalc`` and ``CalcResourceService.SetResourceCalc`` for getting and setting calculations.

Generating a resource map from scratch involves the main part of the flow modelling in windPRO.
The steps that are needed are the following:

- Add or download terrain and roughness data
- Make a statgen object for statistical wind resource calculations
- Do a Statgen calculation to get the wind statistics
- Add a statgen object for resource map calculation and link the wind statistics
- Make a WTG area to decide the limits of your calculation
- Make a resource calculation linking the statgen for resource object and the WTG area object

It is more informative to understand this form an example.
The code below illustrates how to make a resource map from scratch.
it is the same code use to illustrate :ref:`calculations_statgen`.
