Project:
Cronalaght demonstration - Energy calculation
Description:
Licensed user:
This project primarily illustrates how to calculate energy production, based on
either EU-Wind Atlas data, or on local measurements. Also ATLAS contra WASP is
illustrated, and the powerfull VISUAL module for excact positioning of the WTGs,
measuremasts etc. And the Auto optimization of the camera propertied - try the
Air View photo, this would be impossible to find the exact photo point without
this feature.
The data is fully renewed in WindPRO 2.8 - it turned out the coordinate system
was NOT Irish Grid, but Irish Transverse Mercator. And the turbine positions
thereby also some wrong - they was found exact on Google map. These
modifications brought many "not too well fitting" photomontages to an exact fit.
Lesson learned: If things do not fit fully, something is wrong with your data!
Also the ned 2.8 elevation grid object is demonstrated.

Project:
Cronalaght demonstration - Energy calculation
Description:
Licensed user:
This project primarily illustrates how to calculate energy production, based on
either EU-Wind Atlas data, or on local measurements. Also ATLAS contra WASP is
illustrated, and the powerfull VISUAL module for excact positioning of the WTGs,
measuremasts etc. And the Auto optimization of the camera propertied - try the
Air View photo, this would be impossible to find the exact photo point without
this feature.
The data is fully renewed in WindPRO 2.8 - it turned out the coordinate system
was NOT Irish Grid, but Irish Transverse Mercator. And the turbine positions
thereby also some wrong - they was found exact on Google map. These
modifications brought many "not too well fitting" photomontages to an exact fit.
Lesson learned: If things do not fit fully, something is wrong with your data!
Also the ned 2.8 elevation grid object is demonstrated.

was NOT Irish Grid, but Irish Transverse Mercator. And the turbine positions
thereby also some wrong - they was found exact on Google map. These
modifications brought many "not too well fitting" photomontages to an exact fit.
Lesson learned: If things do not fit fully, something is wrong with your data!
Also the ned 2.8 elevation grid object is demonstrated.
