Greetings,

This is our first post.

We are looking to use GRASS as part of our Wind Turbine Site Analysis.

Is there a module available that has been written to calculate Shadow Flicker? We will be using OS DTM data and correseponding Map Overlays.

Many Thanks

Regards,

Neil Woodhouse

Do you want to analyse the *ground* affected by flicker or reflections?

Here an addon which may be of interest:

Hi Markus,

We are interested in the ground effect. Specifically over distances
nominally 10 times the blade diameter of the various turbines we survey for,
and 130 deg either side of north.

This module looks very, very useful for our requirements.

Can I get back to you with other questions when I have had a chance to have
a look at this please

Thank you for pointing this out.

Kind Regards

Neil
